Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement. Lubricate all parts with clean hydraulic oil during assembly.1. Be sure all of the parts of the hoist and brake pump are clean and free of dirt and foreign material.2. Check the condition of all O-ring seals used in the hoist and brake pump. If any of the seals are worn or damaged, use new parts for replacement. 3. Inspect all of the parts for the rear section of the pump. Check the bores in the body for wear. Measure the depth of the groove in each bore. If the groove is deeper than 0.38 mm (0.015 inch), a replacement of the rear section and gears must be made. 4. Inspect all of the parts for the front section of the pump. Check the bores in the body for wear. Measure the depth of the grooves in each bore. If the groove is deeper than 0.38 mm (0.015 inch), a replacement of the front section and gears must be made.
The isolation plate that is installed in the bottom of the pump body must have a radius along its outer edge which must be facing toward the bottom when installed.
5. Install splined coupling (1) and O-ring seal (2) in the housing.6. Put the body in position on the housing. 7. Put clean hydraulic oil on the bores of the body. Install isolation plate (4) with the radius on the plate toward the bottom. The plate must be installed on the inlet side of the pump.8. Install back-up ring (3), seal (6) and ring retainer (5). The radius along the edge of the ring retainer must be toward the bottom of the body.
Do NOT use force to install the pressure plates. Hold the plates as level as possible and slide them into position.
9. Install pressure plate (7) in the pump. The bronze side of the pressure plate must be toward the gears and the machined notch (trap slot) toward the outlet side of the pump. 10. Install driver gear (12) and idler gear (8) in the pump body.11. Install the pressure plate on the gears. The bronze side of the pressure plate must be toward the gears and the machined notch (trap slot) toward the outlet side of the pump.12. Install isolation plate (11) on the inlet side of the pump.13. Install back-up ring (13), seal (9) and ring retainer (10). 14. Install inner lip seal (14) in the flange with Tooling (A). Install the seal
