Introduction

This Manual provides service information for Eaton Heavy Series 2 Variable Displacement Pumps, Models 33, 39, 46, 54 and

64.   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 disconnect the hydraulic lines.

•

Plug the pump ports and cover the open hydraulic lines immediately after they’re disconnected.

•

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.  Dot not wipe them dry with paper towels or cloth: lint in a hydraulic system

 will cause damage.

•

The compressed air should be filtered and moisture free.

•

Always use new seals when reassembling hydraulic pumps.

•

Lubricate the new rubber seals with a petroleum jelly like 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.
