THREADED FASTENERS

Threaded fasteners, like bolts, nuts, cap screws, and studs, are made to specifications that describe the mechanical strength and hardness of the fastener. A fastener used in a design application is selected according to its specifications. Yale® Company buys parts from many countries. Parts that are purchased must be to Yale® Company standards. There are several standards used by these countries in the manufacture of threaded fasteners. Many of these fasteners are similar, but cannot be used as a direct replacement. To make sure that you have the correct fastener, order fasteners and parts through the Yale® Parts Depot.

Service persons must use replacement fasteners that have the same specifications. Fasteners made to each specification have identification marks for that specification. This specification is commonly called "Grade" for SAE standards and "property class" for metric standards. This section describes the identification of some common fasteners.

The metric system used by Yale® Company is described as SI (Le Systeme d'Unites or the International System of units, also called SI in all languages). The SI System of measurement is described in ISO Standard 1000, 1973. A conversion table of common measurements is shown in Table 7.

NOMENCLATURE, THREADS

The thread design is specified by a series of numbers and letters for inch and metric fasteners. See Figure 1.

The diameter of the shank of the fastener is shown first in the series [M12 = 12 mm, M20 = 20 mm (1/2 = 1/2 in., 3/4 = 3/4 in.)].

The number of threads per inch is normally not shown for inch nomenclature and only the UNC (Unified National Coarse) or UNF (Unified National Fine) is shown. This number of threads per inch is not shown because a UNC or UNF fastener has a standard number of threads per inch for a specific diameter. Metric fasteners show the number of threads per millimeter.

The length of the shank is often indicated as part of the description of a fastener. This length is shown in inches for inch fasteners and in millimeters for metric fasteners.

A cap screw will have the following description:

Metric Inch

M12 × 1.75 × 50 1/2 × 13 UNC × 1-1/2

A B C A B C D

A = Thread Size A = Shank Diameter

B = Pitch

C = Length

B = Number of Threads Per Unit of Length

C = type of Thread

D = Shank Length

STRENGTH IDENTIFICATION

CAUTION

When fasteners must be replaced, the new fasteners must be of the same strength or greater than the original fasteners. The new fasteners must also be the correct size.

NOTE: Identification marks are according to bolt strength. The higher the number or the increase in the number of marks indicates increased bolt strength.

The most common property classes for metric fasteners are 8.8 and 10.9. The property class is marked with a number on the head of the cap screw or on a nut. Property classes less than 8.8 are often not marked. Grades for inch bolts go from 2 to 8. Grade 2 fasteners normally do not have any marks. The following tables show the marks that identify the grades and property classes for different fasteners.

General 8000 YRM 0231 2

COTTER (SPLIT) PINS

Cotter (split) pins are used in many applications on your forklift. They are typically used to retain parts such as pins and nuts. Cotter (split) pins are typically not used as load-bearing members. Service personnel must use new cotter (split) pins. Do not reuse a cotter (split) pin. Replacement cotter (split) pin must be of the correct size. See Table 8.

The legs of a cotter (split) pin are bent for the following reasons:

• To retain the cotter (split) pin in the part

• To provide clearance between the cotter pin legs and other parts or members. One or both cotter (split) pin legs must be bent to provide a minimum 90° angle between the legs. See Figure 2.

Unless otherwise specified, the legs of chain anchor cotter (split) pins are to be bent against the pin. See Figure 3.

SAFETY PRECAUTIONS MAINTENANCE

AND REPAIR

• When lifting parts or assemblies, make sure all slings, chains, or cables are correctly fastened, and that the load being lifted is balanced. Make sure the crane, cables, and chains have the capacity to support the weight of the load.

•Do not lift heavy parts by hand, use a lifting mechanism.

•Wear safety glasses.

• DISCONNECT THE BATTERY CONNECTOR before doing any maintenance or repair on electric lift trucks. Disconnect the battery ground cable on internal combustion lift trucks.

• Always use correct blocks to prevent the unit from rolling or falling. See HOW TO PUT THE LIFT TRUCK ON BLOCKS in the Operating Manual or the Periodic Maintenance section.

•Keep the unit clean and the working area clean and orderly.

•Use the correct tools for the job.

•Keep the tools clean and in good condition.

• Always use APPROVED parts when making repairs. Replacement parts must meet or exceed the specifications of the original equipment manufacturer.

• Make sure all nuts, bolts, snap rings, and other fastening devices are removed before using force to remove parts.

• Always fasten a DO NOT OPERATE tag to the controls of the unit when making repairs, or if the unit needs repairs.

•Be sure to follow the WARNING and CAUTION notes in the instructions.

• Gasoline, Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), and Diesel fuel are flammable. Be sure to follow the necessary safety precautions when handling these fuels and when working on these fuel systems.

• Batteries generate flammable gas when they are being charged. Keep fire and sparks away from the area. Make sure the area is well ventilated.

NOTE: The following symbols and words indicate safety information in this manual:

WARNING

Indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION

Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury and property damage.

THREADED FASTENERS

Threaded fasteners, like bolts, nuts, capscrews, and studs, are made to specifications that describe the mechanical strength and hardness of the fastener. A fastener used in a design application is selected according to its specifications. Yale® Company buys parts from many countries. Parts that are purchased must be to Yale® Company standards. There are several standards used by these countries in the manufacture of threaded fasteners. Many of these fasteners are similar, but cannot be used as a direct replacement. To make sure that you have the correct fastener, order fasteners and parts through the Yale® Parts Depot.

Service persons must use replacement fasteners that have the same specifications. Fasteners made to each specification have identification marks for that specification. This specification is commonly called "Grade" for SAE standards and "property class" for metric standards. This section describes the identification of some common fasteners.

The metric system used by Yale® Company is described as SI (Le Systeme d'Unites or the International System of units, also called SI in all languages). The SI System of measurement is described in ISO Standard 1000, 1973. A conversion table of common measurements is shown in Table 7.

NOMENCLATURE, THREADS

The thread design is specified by a series of numbers and letters for inch and metric fasteners. See Figure 1.

The diameter of the shank of the fastener is shown first in the series [M12 = 12 mm, M20 = 20 mm (1/2 = 1/2 in., 3/4 = 3/4 in.)].

The number of threads per inch is normally not shown for inch nomenclature and only the UNC (Unified National Coarse) or UNF (Unified National Fine) is shown. This number of threads per inch is not shown because a UNC or UNF fastener has a standard number of threads per inch for a specific diameter. Metric fasteners show the number of threads per millimeter.

The length of the shank is often indicated as part of the description of a fastener. This length is shown in inches for inch fasteners and in millimeters for metric fasteners.

A capscrew will have the following description:

Metric Inch

M12 × 1.75 × 50 1/2 × 13 UNC × 1-1/2

A B C

A B C D

A = Thread Size A = Shank Diameter

B = Pitch

C = Length

B = Number of Threads Per Unit of Length

C = type of Thread

D = Shank Length

8000 YRM 0231 General 1
Figure 1. Thread Design

STRENGTH IDENTIFICATION

CAUTION

When fasteners must be replaced, the new fasteners must be of the same strength or greater than the original fasteners. The new fasteners must also be the correct size.

NOTE: Identification marks are according to bolt strength. The higher the number or the increase in the number of marks indicates increased bolt strength.

The most common property classes for metric fasteners are 8.8 and 10.9. The property class is marked with a number on the head of the capscrew or on a nut. Property classes less than 8.8 are often not marked. Grades for inch bolts go from 2 to 8. Grade 2 fasteners normally do not have any marks. The following tables show the marks that identify the grades and property classes for different fasteners.

COTTER (SPLIT) PINS

Cotter (split) pins are used in many applications on your forklift. They are typically used to retain parts such as pins and nuts. Cotter (split) pins are typically not used as load-bearing members. Service personnel must use new cotter (split) pins. Do not reuse a cotter (split) pin. Replacement cotter (split) pin must be of the correct size. See Table 8.

The legs of a cotter (split) pin are bent for the following reasons:

• To retain the cotter (split) pin in the part

• To provide clearance between the cotter pin legs and other parts or members. One or both cotter (split) pin legs must be bent to provide a minimum 90° angle between the legs. See Figure 2.

Unless otherwise specified, the legs of chain anchor cotter (split) pins are to be bent against the pin. See Figure 3.

SAFETY PRECAUTIONS MAINTENANCE

AND REPAIR

• When lifting parts or assemblies, make sure all slings, chains, or cables are correctly fastened, and that the load being lifted is balanced. Make sure the crane, cables, and chains have the capacity to support the weight of the load.

•Do not lift heavy parts by hand, use a lifting mechanism.

•Wear safety glasses.

• DISCONNECT THE BATTERY CONNECTOR before doing any maintenance or repair on electric lift trucks. Disconnect the battery ground cable on internal combustion lift trucks.

• Always use correct blocks to prevent the unit from rolling or falling. See HOW TO PUT THE LIFT TRUCK ON BLOCKS in the Operating Manual or the Periodic Maintenance section.

•Keep the unit clean and the working area clean and orderly.

•Use the correct tools for the job.

•Keep the tools clean and in good condition.

• Always use APPROVED parts when making repairs. Replacement parts must meet or exceed the specifications of the original equipment manufacturer.

• Make sure all nuts, bolts, snap rings, and other fastening devices are removed before using force to remove parts.

• Always fasten a DO NOT OPERATE tag to the controls of the unit when making repairs, or if the unit needs repairs.

•Be sure to follow the WARNING and CAUTION notes in the instructions.

• Gasoline, Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), and Diesel fuel are flammable. Be sure to follow the necessary safety precautions when handling these fuels and when working on these fuel systems.

• Batteries generate flammable gas when they are being charged. Keep fire and sparks away from the area. Make sure the area is well ventilated.

NOTE: The following symbols and words indicate safety information in this manual:

WARNING

Description

DISTRIBUTOR IGNITION (DI) SYSTEM

The distributor ignition (DI) system is responsible for producing and controlling a high energy secondary spark. This spark is used to ignite the compressed air/ fuel mixture at precisely the correct time. This provides optimal performance, fuel economy, and control of exhaust emissions. This ignition system consists of a single ignition coil and ignition control module (ICM). Spark energy is delivered via a distributor cap, rotor, and secondary spark plug wires. The driver module within the ICM is commanded to operate the coil by the electronic control module (ECM), that has complete control over spark timing. The DI system consists of a Crankshaft Position (CKP) Sensor, Camshaft Position (CMP) Sensor, Ignition Coil and Ignition Control Module (ICM), and Secondary Ignition Components.

CRANKSHAFT POSITION (CKP) SENSOR

The CKP sensor is a three-wire sensor based on the magneto-resistive principle. A magneto-resistive sensor uses two magnetic pickups between a permanent magnet. As an element such as a reluctor wheel passes the magnets, the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. The ECM supplies a 5volt, low reference and signal circuit to the CKP sensor. The sensor returns a digital ON/OFF pulse 3 times per crankshaft revolution. The CKP sensor reads the crankshaft mounted reluctor wheel to identify pairs of cylinders at top dead center (TDC).

CAMSHAFT POSITION (CMP) SENSOR

The CMP sensor is a hall-effect sensor located in the ignition distributor base, and uses the same type of circuits as the CKP sensor. The CMP sensor signal is a digital ON/OFF pulse, output once per revolution of the camshaft. The CMP sensor information is used by the ECM to determine the position of the valve train relative to the CKP.

IGNITION COIL AND IGNITION CONTROL MODULE (ICM)

The ICM is connected to the ECM by an ignition control (IC) circuit. The ICM also has a ground circuit and shares an ignition 1 voltage supply with the ignition coil. The coil driver in the ICM controls current through the ignition coil based on signal pulses from the ECM. There is no backup or bypass function in the ICM.

SECONDARY IGNITION COMPONENTS

The distributor is only used as a means to operate the CMP sensor and to distribute spark in the correct sequence. Since the distributor has no influence on base timing, the distributor is not adjustable. The spark is distributed through conventional carbon core wires to the spark plugs.

Spark Plugs and Wires

SPARK PLUG WIRE INSPECTION

Spark plug wire integrity is vital for proper engine operation. A thorough inspection will be necessary to accurately identify conditions that may affect engine operation. Inspect for the following conditions:

1. Correct routing of the spark plug wires. Incorrect routing may cause cross-firing.

2. Any signs of cracks or splits in the wires.

3. Inspect each boot for the following conditions:

• Tearing

• Piercing

• Arcing

• Carbon tracking

• Corroded terminal

If corrosion, carbon tracking, or arcing are indicated on a spark plug wire boot or on a terminal, replace the wire and the component connected to the wire.

SPARK PLUG WIRE REPLACEMENT

Remove

1. Disconnect the spark plug wire at each spark plug. See Figure 1.

a. Twist the boots 1/2 turn before removing the boots.

b. Pull only on the boot or use a tool designed for this purpose in order to remove the wire from each spark plug.

1.SPARK PLUG WIRES

Figure 1. Spark Plug Wire Removal/Installation

2. Disconnect the spark plug wire from the distributor.

a. Twist each spark plug boot 1/2 turn.

b. Pull only on the boot or use a tool designed for this purpose in order to remove the wires from the distributor.

2200 YRM 1097 Spark Plugs and Wires 3

Install

NOTE: If the boot-to-wire movement has occurred, the boot will give a false visual impression of being fully seated. Ensure that the boots have been properly assembled by pushing sideways on the installed boots. Failure to properly seat the terminal onto the spark plug will lead to wire core erosion and result in an engine misfire or crossfire condition and possible internal damage to the engine.

1. Install the spark plug wires at the distributor.

2. Install the spark plug wire to each spark plug. See Figure 1.

3. Inspect the wires for proper installation:

a. Push sideways on each boot in order to inspect the seating.

b. Reinstall any loose boot.

c. Wire routing must be kept intact during service and followed exactly when wires have been disconnected or when replacement of the wires is necessary. Failure to route the wires properly can lead to radio ignition noise and cross firing of the plugs or shorting of the leads to the ground.

d. Any time the spark plug wires or boots are installed on the spark plugs, new dielectric grease needs to be applied inside the boot.

SPARK PLUG INSPECTION

Usage

1. Ensure that the correct spark plug is installed. An incorrect spark plug causes driveability conditions. Refer to Table 1 for the correct spark plug.

2. Ensure that the spark plug has the correct heat range. An incorrect heat range causes the following conditions:

• Spark plug fouling - Colder plug

• Pre-ignition causing spark plug and/or engine damage - Hotter plug

Inspection

1. Inspect the terminal post for damage. See Figure 2.

a. Inspect for a bent or broken terminal post.

1.TERMINAL POST 2.INSULATOR 3.ELECTRODE 4.ELECTRODE

Figure 2. Spark Plug

b. Test for a loose terminal post by twisting and pulling the post. The terminal post should NOT move.

Spark Plugs and Wires 2200 YRM 1097 4

2. Inspect the insulator for flashover or carbon tracking, soot. See Figure 3. This is caused by the electrical charge traveling across the insulator between the terminal post and ground. Inspect for the following conditions:

1.TERMINAL POST 2.INSULATOR 3.ELECTRODE 4.ELECTRODE

Figure 3. Spark Plug With Flashover or Carbon Tracking

a. Inspect the spark plug boot for damage.

b. Inspect the spark plug recess area of the cylinder head for moisture, such as oil, coolant, or water. A spark plug boot that is saturated causes arcing to ground.

3. Inspect the insulator for cracks. All or part of the electrical charge may arc through the crack instead of the electrodes. See Figure 4.

4. Inspect for evidence of improper arcing. See Figure 5.

a. Measure the gap between the center electrode (4) and the side electrode (3) terminals. An excessively wide electrode gap can prevent correct spark plug operation.

b. Inspect for the correct spark plug torque. Refer to Table 1. Insufficient torque can prevent correct spark plug operation. An over-torqued spark plug causes the insulator to crack.

1.TERMINAL POST 2.INSULATOR 3.ELECTRODE 4.ELECTRODE

Figure 4. Spark Plug Arcing Through a Crack

1.TERMINAL POST 2.INSULATOR 3.ELECTRODE 4.ELECTRODE

Figure 5. Spark Plug Arcing Improperly

c. Inspect for signs of tracking that occurred near the insulator tip instead of the center electrode (4).

d. Inspect for a broken or worn side electrode (3).

2200 YRM 1097 Spark Plugs and Wires 5

e. Inspect for a broken, worn, or loose center electrode (4) by shaking the spark plug.

(1) A rattling sound indicates internal damage.

(2) A loose center electrode (4) reduces the spark intensity.

f. Inspect for bridged electrodes (3, 4). Deposits on the electrodes (3, 4) reduce or eliminate the gap.

g. Inspect for worn or missing platinum pads on the electrodes (3, 4) if equipped.

h. Inspect for excessive fouling.

5. Inspect the spark plug recess area of the cylinder head for debris. Dirty or damaged threads can cause the spark plug not to seat correctly during installation.

Visual Inspection

1. Normal operation - Brown to grayish-tan with small amounts of white powdery deposits are normal combustion by-products from fuels with additives.

2. Carbon fouled - Dry, fluffy black carbon, or soot caused by the following conditions:

• Rich fuel mixtures

• Leaking fuel injectors

• Excessive fuel pressure

• Restricted air filter element

• Incorrect combustion

• Reduced ignition system voltage output

• Weak coils

• Worn ignition wires

• Incorrect spark plug gap

• Excessive idling or slow speeds under light loads can keep spark plug temperatures so low that normal combustion deposits may not burn off.

3. Deposit Fouling - Oil, coolant, or additives that include substances such as silicone, very white coating, reduces the spark intensity. Most powdery deposits will not effect spark intensity unless they form into a glazing over the electrode.

SPARK PLUG REPLACEMENT

Remove

1. Remove the spark plug wires. Refer to Spark Plug Wire Replacement.

2. Loosen each spark plug 1 or 2 turns.

3. Brush or air blast away any dirt from around the spark plugs.

4. Remove the spark plugs one at a time. Place each plug in a tray marked with the corresponding cylinder numbers. See Figure 6.

Install

1. Properly position each spark plug washer.

2. Inspect each spark plug gap. Adjust each plug as needed. See Table 1.

CAUTION

Late model engines use a combination of standard and metric fasteners. The components affected are the starter motor, engine mounts, and flywheel housing mounting. Other components may also have a combination of fasteners. Always verify that the proper fasteners are used whenever removing or replacing any components.

3. Hand start the spark plugs in the corresponding cylinders. See Figure 6.

4. Tighten the spark plugs.

a. For used heads, tighten the spark plugs to 15 N•m (11 lbf ft).

Figure 6. Spark Plug Removal/Installation
Spark Plugs and Wires 2200 YRM 1097 6

b. For new aluminum heads, tighten the spark plugs to 20 N•m (15 lbf ft).

GENERAL INSTRUCTIONS

1Become familiar with the content, layout, and access provisions of data in this manual. This will improve your efficiency and decrease the time required to resolve the problems.

2Use all sections of the manual for relevant information on the subject system.

3Once you begin a troubleshooting procedure, do not skip steps.

4If you reach the end of a procedure without resolving the problem and you are not directed to another procedure contact Resident Service Engineering through the Contact Management System.

5Do not limit yourself, remember to apply your own experience and knowledge to assist in resolving the problems, but do not compromise safety in doing so.

6Most of the cross-reference data in the manual will be electronically linked for rapid and easy access. Use the links wherever the cursor highlights an item as a linkable option.

As an example of this linking option:

Assume that during a procedure or test, it is necessary to refer to a different section of manual, in this case, the Light Circuit Check in the Operational Checkout part of this manual.

The instruction would read, "refer to, or see" followed by text identifying what the reference is (for hard-copy, paper manual use). When the cursor is placed over the text, it will then indicate that it is active, and left-clicking will direct the system to take you directly to that reference.
