Important: Cleanliness is extremely important when repairing a hydrostatic pump or motor. Before disconnecting the lines, clean foreign material
from exterior of unit. Work in a clean area. Clean all metal parts in clean solvent. Blow parts dry with air. Don’t wipe parts with cloth or paper towel,
because lint or other matter could cause damage. Check all mating surfaces. Replace any parts that have scratches or burrs that could cause leakage.
Don’t use coarse grit paper, files or grinders on parts.
Note: All torque specifications are for lubricated threads. Bolts for gasketed surfaces should be checked for proper torque.
A good service policy is to replace all old seals with new seals whenever unit is disassembled. Lubricate seals (except metal sealing surfaces of shaft
seal assembly) with petroleum jelly. Use only clean, recommended oil when assembling unit. See Hydrostatic Fluid Recommendations on page 28-29 or
publication 03-401 and 03-405.
Refer to specific motor assembly
part listings for your Eaton motor
when ordering replacement parts.
