Hydrostatic Pump (Right Drive) Removal
Note: Cleanliness is a key factor in a successful
repair of any hydrostatic system.
Thoroughly clean all exposed surfaces
prior to any type of maintenance. Cleaning
all parts by using a solvent wash and air
drying is usually adequate. As with any
precision equipment, all parts must be kept
free of foreign material and chemicals.
Protect all exposed sealing areas and open
cavities from damage and foreign material.
Upon removal, all seals, O-rings, and
gaskets should be replaced. During
installation, lightly lubricate all seals, O-
rings and gaskets with clean petroleum
jelly prior to assembly.
