The following recommendations should be followed to insure successful repairs.
Remove the pump from the application.
Cleanliness is extremely important.
Clean the port areas thoroughly before disconnecting the hydraulic lines.

Drain the oil and clean the exterior of the pump before making repairs.
Wash all metal parts in clean solvent.
Use compressed air to dry the parts. Do not wipe them dry with paper towels or cloth.
The compressed air should be filtered and moisture free.
Always use new seals when reassembling hydraulic pumps.
For replacement parts and ordering information refer to parts list 6-634.
Lubricate the new rubber seals with a petroleum jelly (vaseline) before installation.
