GENERAL INFORMATION Cleaning

Gears

Clean all metal parts except bearings, in mineral spirits or by steam cleaning. Do not use caustic soda for steam cleaning. After cleaning dry and put oil on all parts. Clean oil passages with compressed air. Clean bearings in kerosene, dry the bearings completely and put oil on the bearings.

Check all gears for wear and damage. Replace gears that have wear or damage.

Inspection Check all parts when the parts are disassembled. Replace all parts that have wear or damage. Small scoring or grooves can be removed with a hone or crocus cloth. Complete visual inspection for indications of wear, pitting and the replacement of parts necessary will prevent early failures.

Bearings Check bearings for easy action. If bearings have a loose fit or rough action replace the bearing. Wash bearings with a good solvent or kerosene and permit to air dry. DO NOT DRY BEARINGS WITH COMPRESSED AIR.

Needle Bearings Before you press needle bearings in a bore always remove any metal protrusions in the bore or edge of the bore. Before you press bearings into position put petroleum jelly on the inside and outside diameter of the bearings.

SM 8-10080

Oil Seals, O-Rings And Gaskets Always install new oil seals, o-rings and gaskets. Put petroleum jelly on seals and o-rings.

Shafts Check all shafts that have wear or damage. Check the bearing and oil seal surfaces of the shafts for damage.

Service Parts Always install genuine McCormick service parts, when ordering refer to the Parts Catalog for the correct part number of the genuine McCormick replacement items. Failures due to the use of other than genuine McCormick replacement parts are not covered by warranty.

Lubrication Only use the oils and lubricants specified in the Operators or Service Manual. Failures due to the use of non specified oils and lubricants are not covered by warranty.

General information Introduction This Workshop Manual has been written to provide assistance in the service and overhaul of 1000 Series engines. For overhaul procedures the assumption is made that the engine is removed from the application. The engine conforms with USA (EPA/CARB) stage 1 and EEC stage 1 emissions legislation for agricultural and industrial applications.

Most of the general information which is included in the relevant User's Handbook has not been repeated in this workshop manual and the two publications should be used together. Where the information applies only to certain engine types, this is indicated in the text. When reference is made to the “left” or “right” side of the engine, this is as seen from the flywheel end of the engine. Special tools have been made available, for a list of these, see Chapter 15, Special tools . Reference to the relevant special tools is also made at the beginning of each operation, where relevant. Data and dimensions are included in Chapter 2, Specifications . Read and remember the "Safety precautions" on page 15. They are given for your protection and must be used at all times. Danger is indicated in the text by two methods: Warning! This indicates that there is a possible danger to the person. Caution: This indicates that there is a possible danger to the engine. Note: Is used where the information is important, but there is not a danger.

Engine identification The New 1000 Series engines have been designed for industrial and agricultural applications. There are both four and six cylinder engines, each of which will have three basic engine types, naturally aspirated, turbocharged and turbocharged with an intercooler. In this workshop manual, the different engine types are indicated by their code letters. These are the first two letters of the engine number as indicated below: AQ

Four cylinder, turbocharged, belt driven coolant pump

AS

Four cylinder, naturally aspirated, belt driven coolant pump, 103 mm cylinder bore

AT

Four cylinder, turbocharged, belt driven coolant pump, air to air

YG

Six cylinder, naturally aspirated

YH

Six cylinder, turbocharged

YJ

Six cylinder, charge cooled, air to air

YK

Six cylinder, turbocharged and intercooled

The correct identification of the engine is by the full engine number. The engine number is stamped on a label which is fastened to the left side (A2) of the cylinder block. An example of an engine number is: AS50665*U510256B* The components of the engine number are as follows: AS50665*U510256B* AS

Model code number 50665

Build list number U

Built in the UK 510256

Date letters for engines start from the 1st of January each year. To comply with the new emissions legislation that engines built before 1st April 1999 can be clearly identified from those built after this date, a new letter has been used from the 1st of April 1999. The date letters used are as follows: From the 1st of January 1999 to the 31st of March 1999 the date letter is E. From the 1st of April 1999 to the 31st of January 1999 the date letter is F. If you need parts, service or information for your engine, you must give the complete engine number to your McCormick dealer. If there is a number in the area of the label marked TPL No, then this number must also be given to your McCormick dealer. Other identification labels fitted to the engine include: An emissions legislation label (A3) fitted to the side of the cylinder block. A label (A1) with the fuel injection pump part numbers. If a short engine has been fitted in service two engine serial numbers and a TPL number are stamped on the engine serial number pad (B3). Examples of the serial numbers are shown in (B). If parts for the short engine are needed in service, use the serial number (B4). If parts which were moved from the original engine to the short engine are needed, use the serial number (B1) and the TPL number (B2).

Safety precautions These safety precautions are important. You must refer also to the local regulations in the country of use. Some items only refer to specific applications. * Only use these engines in the type of application for which they have been designed. * Do not change the specification of the engine. * Do not smoke when you put fuel in the tank. * Clean away fuel which has been spilt. Material which has been contaminated by fuel must be moved to a safe place. * Do not put fuel in the tank while the engine runs (unless it is absolutely necessary). * Do not clean, add lubricating oil, or adjust the engine while it runs (unless you have had the correct training; even then extreme care must be used to prevent injury). * Do not make adjustments that you do not understand. * Ensure that the engine does not run in a location where it can cause a concentration of toxic emissions. * Other persons must be kept at a safe distance while the engine or auxiliary equipment is in operation. * Do not permit loose clothing or long hair near moving parts. * Keep away from moving parts during engine operation. Warning! Some moving parts cannot be seen clearly while the engine runs. * Do not operate the engine if a safety guard has been removed. * Do not remove the filler cap or any component of the cooling system while the engine is hot and while the coolant is under pressure, because dangerous hot coolant can be discharged. * Do not allow sparks or fire near the batteries (especially when the batteries are on charge) because the gases from the electrolyte are highly flammable. The battery fluid is dangerous to the skin and especially to the eyes. * Disconnect the battery terminals before a repair is made to the electrical system. * Only one person must control the engine. * Ensure that the engine is operated only from the control panel or from the operators position. * If your skin comes into contact with high-pressure fuel, obtain medical assistance immediately. * Diesel fuel and lubricating oil (especially used lubricating oil) can damage the skin of certain persons. Protect your hands with gloves or a special solution to protect the skin. * Do not wear clothing which is contaminated by lubricating oil. Do not put material which is contaminated with oil into the pockets of clothing. * Discard used lubricating oil in a safe place to prevent contamination. * Ensure that the control lever of the transmission drive is in the “out-of-drive� position before the engine is started. * Use extreme care if emergency repairs must be made in adverse conditions. * The combustible material of some components of the engine (for example certain seals) can become extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or with the eyes, see "Viton seals" on page 16 for safety precautions. * Read and use the instructions relevant to lift equipment, see "Engine lift equipment" on page 17.

Section 1 - General Information

* Always use a safety cage to protect the operator when a component is to be pressure tested in a container of water. Fit safety wires to secure the plugs which seal the hose connections of a component which is to be pressure tested. * Do not allow compressed air to contact your skin. If compressed air enters your skin, obtain medical help immediately. * Turbochargers operate at high speed and at high temperatures. Keep fingers, tools and items away from the inlet and outlet ports of the turbocharger and prevent contact with hot surfaces. * Do not clean an engine while it runs. If cold cleaning fluids are applied to a hot engine, certain components on the engine may be damaged. * Fit only genuine McCormick parts.

Viton seals Some seals used in engines and in components fitted to engines are made of Viton. Viton is used by many manufacturers and is a safe material under normal conditions of operation. If Viton is burned, a product of this burnt material is an acid which is extremely dangerous. Never allow this burnt material to come into contact with the skin or with the eyes. If it is necessary to come into contact with components which have been burnt, ensure that the precautions which follow are used: * Ensure that the components have cooled * Use neoprene gloves and discard the gloves safely after use * Wash the area with calcium hydroxide solution and then with clean water * Disposal of components and gloves which are contaminated must be in accordance with local regulations. If there is contamination of the skin or eyes, wash the affected area with a continuous supply of clean water or with calcium hydroxide solution for 15-60 minutes. Obtain immediate medical attention.

Engine lift equipment The maximum weight of the engine without coolant, lubricant or a gearbox fitted will vary for different applications. It is recommended that lift equipment of the minimum capacity listed below is used: Four cylinder engines

500 kg (1100 lbs)

Six cylinder engines

600 kg (1320 lbs)

Before the engine is lifted: * Always use lift equipment of the approved type and of the correct capacity to lift the engine. It is recommended that lift equipment of the type shown in (A) is used, to provide a vertical lift directly above the engine lift brackets (A1). Never use a single lift bracket to raise an engine * Check the engine lift brackets for damage and that they are secure before the engine is lifted. The torque for the setscrews for the engine lift brackets is 44 Nm (33 lbf ft) 4,5 kgf m * To prevent damage to the rocker cover, ensure that there is clearance between the hooks and the rocker cover * Use lift equipment or obtain assistance to lift heavy engine components such as the cylinder block, cylinder head, balancer unit, flywheel housing, crankshaft and flywheel.
