15. Install the idler spring onto the tab on the chassis

Note: Cleanliness is a key factor in a successful

repair of any hydraulic system. Thoroughly

clean all exposed surfaces prior to any type

of maintenance. Cleaning all parts by using

a solvent wash and air drying is usually

adequate. As with any precision equipment,

all parts must be kept free of foreign material

and chemicals. Protect all exposed sealing

areas and open cavities from damage and

foreign material.

Upon removal, all seals, O-rings, and gaskets

should be replaced. During installation, lightly

lubricate all seals, O-rings, and gaskets with

clean petroleum jelly prior to assembly.

For wheel motor service information, refer

to Parker/Ross Wheel Motor Service Manual

Note: The following procedures can be followed for

both the right and the left wheel motor.
