Single Gear Pump 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: mast, drive axle, engine, 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.

1. Put the lift truck on blocks. See the Operating Manual or the Periodic Maintenance Manual for your lift truck for the procedures to put the lift truck on blocks. 2. Place a drain pan under the hydraulic tank, remove drain plug at the bottom of hydraulic oil tank, and drain oil from tank. a. Drain pan capacity approximately ter (8 gal) for lift truck models

Tandem Gear Pump Assembly 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: mast, drive axle, engine, 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 any blocks used to support the lift truck are solid, one-piece units. NOTE: Worn or damaged seals are the most common cause of pump damage. The pump bushings, gears, and shafts also wear. They must be checked during disassembly. DO NOT make any repairs to the parts. To prevent more failures, always replace parts that are worn or damaged. If several main parts need replacing, replace the complete group. 1. Put the lift truck on blocks.

6. Install a new shaft seal in the drive pump flange end housing. Carefully install the flange end housing. DO NOT move the pressure plates. Make sure the seals do not move out of the correct position. 7. Carefully install the adapter plate on the drive pump body using the four socket head screws and lock washers. Make sure the pressure plates do not move and that the seals stay in the correct position. Make sure the marks made during disassembly are aligned. Tighten the capscrews to 123 to 132 N•m (91 to 97 lbf ft). Install new snap ring in front of shaft seal. 8. Assemble tandem gear pump. Place drive pump in vise and install oil seal, adapter, sleeve and Oring to shaft of drive pump. Fit shaft of driven pump into adapter and install two capscrews and washers securing the driven pump to the drive pump. Tighten the capscrews to 42 to 46 N•m (31 to 34 lbf ft).

10. Install two inlet adapters, tighten to 88 to 98 N•m (65 to 72 lbf ft). Remove tandem gear pump from vise.

1. Clean the tandem gear pump flange and transmission charge pump mounting surfaces and put a 3-5 mm (0.118-0.197 in.) bead of Loctite™ 515 (Yale Part No. 520042831) on the pump flange or transmission charge pump mounting surface. Hold the pump in the correct position on the transmission. Install the socket head screws and lockwashers that fasten the pump to the transmission housing. Tighten socket head screws to 108 N•m (80 lbf ft). See Figure 12. 2. Loosen inlet hose clamps and install inlet hoses to inlet hose fittings. Tighten inlet hose clamps. Install outlet hoses to outlet hose fittings. 3. Remove the lift truck from the blocks. See the Operating Manual or the Periodic Maintenance Manual for the procedures to remove lift truck from blocks. 4. Fill the tank using the hydraulic oil shown in the Maintenance Table located in the Operating Manual or the Periodic Maintenance Manual for your lift truck model.

Variable Displacement Pump Repair REMOVE WARNING

Periodic Maintenance 8000YRM1248 for lift truck models •

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: mast, drive axle, engine, 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 any blocks used to support the lift truck are solid, one-piece units. NOTE: Worn or damaged seals and O-rings are the most common cause of pump damage. The pump shaft, plugs, and plates also wear. They must be checked during disassembly. DO NOT make any repairs to the parts. To prevent more failures, always replace parts that are worn or damaged. If several main parts need replacing, replace the with a new pump. 1. Put the lift truck on blocks. See the Operating Manual or one of the following service manuals for the procedures to put the lift truck on blocks:

Variable Displacement Pump Checks and Adjustments

Variable Displacement Pump Checks and Adjustments MARGIN PRESSURE CHECK The margin pressure is the difference between the pressure at the P-port and LS-port. If the margin pressure is not within the range shown in Table 7, the flow of hydraulic oil out of the variable displacement pump (VDP) will be either too low or too high. Table 7. Margin Pressure Lift Truck Model

Margin Pressure
