Refer to specific part
listings for your Eaton
pump when ordering
replacement parts.

from Eaton. Sample tag

When ordering replace-
ment parts, you must
include the following
information:
This Manual provides parts and service information for Eaton®Heavy Series 2
Hydrostatic Piston Pumps, Models 3322, 3922, 4622, 5422 and 6422. Step by step
instructions for complete disassembly, inspection and reassembly of the pump are
given.
The following recommendations should be followed to insure successful repairs.
• Most repairs require the removal of the pump from the vehicle.
• Cleanliness is extremely important.
• Clean the port areas thoroughly before disconnecting the hydraulic lines.
• Plug the pump ports and cover open hydraulic lines immediately after they have
been disconnected.
• Drain the oil and clean the exterior of the pump before making repairs.
• Wash all metal parts in clean solvent.
• Use filtered, moisture-free compressed air to dry the parts. Dot not wipe them
dry with paper towels or cloth – lint in a hydraulic system will cause damage.
• Always use new seals when reassembling hydraulic pumps.
• Lubricate new rubber seals with a petroleum jelly (Vaseline®) before installation.
• Torque all bolts over gasketed joints, then repeat the torquing sequence to make
up for gasket compression.
After all repairs are complete it is essential to verify the accuracy of pump repairs
on an authorized test stand.
