Operator Module Repair

General WARNING The lift truck must be put on blocks for some types of maintenance and repair. The removal of the following assemblies will cause large changes in the center of gravity: mast, drive axle, engine and transmission, and counterweight. When the lift truck is put on blocks, put additional blocks in the following positions to maintain stability: • Before removing the mast and drive axle, put blocks under the counterweight so the lift truck cannot fall backward.

• Before removing the counterweight, put blocks under the mast assembly so the lift truck cannot fall forward.

The surface must be solid, even, and level when the lift truck is put on blocks. Make sure that any blocks used to support the lift truck are solid, one-piece units. See the Operating Manual or Periodic Maintenance 8000 SRM 707.

This section has the description of the frame and some connected parts. See Figure 1. Procedures for the removal and installation of the counterweight, hood, overhead guard, and engine (including the transmission) are found in this section. Checks for the operator restraint system and procedures for the repair of tanks and installation of safety labels are also included.

Description The frame is one weldment and includes the hydraulic tank and the fuel tank for gasoline or diesel fuel.

There is a counterweight for each capacity of lift truck. The counterweights are similar, but are different weights. The muffler is fastened to the frame inside the counterweight.

An operator module is installed on the frame with rubber mounts. The overhead guard, steering controls, instrument panel, hood, and seat are installed on the operator module.

The hood is connected to the operator module with hinges. Two gas-controlled springs give assistance when raising the hood and hold the hood in the open position. The floor plates and side covers can be removed for access to the engine, transmission, and other components.

When cleaning the tank, do not use solutions that make dangerous gases at normal temperatures or when heated. Wear eye and face protection. Protect the body from burns.

When cleaning with steam, use a hose with a minimum diameter of 19 mm (0.75 in.). Control the pressure of the steam by a valve installed at the nozzle of the hose. If a metal nozzle is used, it must be made of a material that does not make sparks. Make an electrical connection between the nozzle and the tank.

Connect a ground wire to the tank to prevent static electricity.

If the tank cannot be cleaned with steam, use the following procedure:

Steam Method of Cleaning Use the following procedure to clean the tank with steam: 1. Remove all the parts from the tank. Install the drain plug.

1. Mix a solution of water and trisodium phosphate or a cleaning compound with an alkaline base.

Follow the instructions given by the manufacturer.

2. Fill the tank with the cleaning solution. Use compressed air to mix the solution in the tank.

3. Drain the tank. Flush the inside of the tank with hot (boiling) water. Make sure all the cleaning compound is removed.

2. Fill the tank 1/4 full with a solution of water and sodium bicarbonate or sodium carbonate. Mix 0.5 kg (1 lb) per 4 liter (1 gal) of water.

4. Make an inspection of the inside of the tank.

If the tank is not clean, repeat Step 1 through Step 3. Make another inspection of the tank.

When making inspections, use a light that is approved for locations with flammable vapors.

3. Mix the solution in the tank using air pressure.

Make sure all the surfaces on the inside of the tank are flushed with the solution. Drain the tank.

5. Check the tank for flammable vapors using special indicator for gas vapors. If the amount of flammable vapors is not below the lower flammable limit, repeat the cleaning procedures.

4. Put steam into the tank until the tank does not have odors and the metal is hot. Steam vapors must come from all the openings.

ADDITIONAL PREPARATIONS FOR REPAIR

5. Flush the inside of the tank with boiling water.

Make sure all the loose material is removed from the inside of the tank.

6. Make an inspection of the inside of the tank. If it is not clean, repeat Step 4 and Step 5 and make another inspection. When making inspections, use a light that is approved for locations with flammable vapors.

Description

General This section has the description and repair procedures for the steering axle. See the following sections for additional information on the parts of the steering system: Steering Housing and Control Unit and Hydraulic System.

Description The steering axle assembly includes an axle frame, steering cylinder, and two spindle and hub assemblies. See Figure 1. The steering axle is connected to the frame with center pivot mounts. The center pivot mounts on the axle frame are fastened to the lift truck frame with rubber mounts. The steering axle can make an articulated motion and gives the lift truck a smoother travel over rough surfaces.

The end caps of the steering cylinder are also the mounts for the cylinder and are held to the shell by the mount capscrews. O-rings, seals, and wipers in the end caps are used to keep the oil inside the

steering cylinder. The ends of the piston rod extend from both ends of the cylinder. A single piston and the seal are at the center of the rod. Oil pressure on one side of the piston moves the piston in the bore. When the piston moves in the bore, it pushes an equal amount of oil from the opposite end of the cylinder. This oil returns to the steering control unit.

When the piston reaches the end of the stroke, a relief valve controls the oil pressure so the components are not damaged. Tie rods connect the spindle arms to the cylinder.

Steering Axle Assembly Repair Each spindle turns on two tapered roller bearings.

The spindle and bearings are held in the axle frame by a kingpin. The preload on the bearings is controlled by a threaded nut on the bottom of the kingpin.

1600 SRM 316 The wheel or hub rotates on two tapered roller bearings and is held on the spindle by a castle nut. The preload on the bearings in the hub is adjusted by the castle nut. A grease seal in the inner hub and a hub cap protect the bearings from dirt and water. A wear sleeve in the inner hub protects the hub from wear by the seal.

Steering Axle Assembly Repair REMOVE WARNING PUTTING THE LIFT TRUCK ON BLOCKS The lift truck must be put on blocks for some types of maintenance and repair. The removal of the following assemblies will cause large changes in the center of gravity: drive axle, battery, or counterweight. When the lift truck is put on blocks, put additional blocks in the following positions: 1. If the mast and drive axle are removed, put blocks under the counterweight so the lift truck cannot fall backward.

2. If the battery (electric lift trucks) or counterweight is removed, put blocks under the mast so the lift truck cannot fall forward.

Put the lift truck on blocks on a solid, even, and level surface. Make sure the blocks of stands have enough capacity to hold the lift truck. Use additional blocks next to the tires as necessary to prevent movement of the lift truck. Make sure the lifting devices used during repairs can lift the weight of the parts and assemblies.

NOTE: The steering axle assembly without the wheels weighs approximately 115 kg (250 lb).

The steering axle can be removed without removing the counterweight. If necessary, remove counterweight as described in the Frame section.

1. Make sure wheels are set for straight travel. Put lift truck on blocks so steering axle can be removed. The top of the axle frame must have clearance under the counterweight so the steering axle can be removed. See Figure 1.

2. Disconnect hydraulic lines at steering cylinder.

Install caps on cylinder and put plugs in hydraulic lines. The caps will prevent spindles from turning when axle is removed from under lift truck.

3. Slide a floor jack or forks of another lift truck under steering axle. Raise lifting device until it holds the weight of the axle assembly. Remove four capscrews and nuts that fasten two brackets under rubber mounts. Remove brackets and slowly lower axle assembly onto wheels. Carefully roll axle assembly from under lift truck.

INSTALL 1. Install rubber mounts on axle as follows (see Figure 1): a. E1.25-1.75XL (E25-35XL), J2.00-3.00XL (J40-60XL), H2.00-3.20XM (H40-65XM), J2.00-3.20XM (J40-60XM, J40-60XM 2) (A216), and J2.00-3.20XM (J40-65Z) (A416/B416): Make sure PART NO. on the mounts is right side up and facing away from axle frame. b. J1.25-1.75XL (Europe only): Make sure PART NO. on mounts is upside down and facing away from axle frame.

2. Apply a lubricant that is approved for use with rubber to rubber mount. The lubricant is used where the rubber mount fits into the frame brackets.

3. Use a floor jack or another lift truck to put steering axle into position in frame. Make sure rubber mounts fit inside frame brackets for mounts.
