Introduction

This manual provides service information for the Eaton model 26000 single gear pumps. Step by step
instructions for the complete disassembly, inspection, and reassembly of the pumps are included.

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.

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. 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.

Torque all bolts over gasket joints, then repeat the torquing sequence to makeup for gasket

compression.

Verifying the accuracy of pump repairs on an authorized test stand is essential.
