Introduction and Part Names
Introduction
This manual provides service information for Eaton Models 33 thru 64 Variable Motors. It’s divided into two main
sections: the first covers minor repairs and the second gives instructions for the complete disassembly, inspection
and reassembly of the motor.
The following recommendations apply to both minor and major repairs:
•
Most repairs require the removal of the motor from the vehicle.
•
Cleanliness is extremely important.
•
Clean the port areas thoroughly before disconnecting the hydraulic lines.
•
Plug the motor ports and cover the open end of the hydraulic line immediately after they’re disconnected.
•
Drain the oil and clean the exterior of the motor 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; Lint in a hydraulic system
will cause damage.
•
The compressed air should be filtered and moisture free.
•
Always use new seals when reassembling hydraulic motors.
•
For replacement parts and ordering information refer to parts list 6-132.
•
Lubricate the new 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.
•
Verifying the accuracy of motor repairs on an authorized test stand is essential.
