CLEAN WARNING Cleaning solvents can be flammable and toxic and can cause skin irritation. When using cleaning solvents, always follow the solvent manufacturers recommended safety precautions.
WARNING
1900 YRM 1136 move and that the seals stay in the correct position. Make sure the marks made during disassembly are aligned. Tighten the capscrews to 88 to 98 N•m (65 to 72 lbf ft).
INSTALL 1. Install pump outlet fitting and tighten to: a. 88 to 98 N•m (65 to 72 lbf ft) for lift truck models below
Compressed air can move particles so that they cause injury to the user or to other personnel. Make sure that the path of the compressed air is away from all personnel. Wear protective goggles or a face shield to prevent injury to the eyes.

INSPECT Check parts for wear and damage. If any parts are worn or damaged, replace the damaged parts. If the pump housing is damaged, replace the pump.
ASSEMBLE 1. Coat all pump components with hydraulic oil. Use hydraulic oil meeting specification ISO VG 46 hydraulic oil −15°C (5°F) and above. 2. Use new plate and backup seals and install the pressure plates and gears. Make sure to install the pressure plates as removed during disassembly. See the notes made during disassembly. Make sure all seals are complete and in the correct positions. See Figure 7. 3. Install a new shaft seal in the 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. See Figure 7. 4. Carefully install the valve end housing on the pump body using the four capscrews and lockwashers. Make sure the pressure plates do not
