Servicing the hydraulic Motor
Perform this procedure using the necessary parts from Motor
Service Kit — Minor (P/N 235-050). If the hydraulic motor is
operable, start the machine and jog the piston rod (19) into its top
position.
NOTE: Servicing of the hydraulic motor should be
carried out in a clean, dust free area only. any
dust or metallic particles left in the motor or
entering it on reassembly may damage the
critical parts and affect its service life and
warranty. all parts should be inspected for
absolute cleanliness.
Disassembling the hydraulic Motor
1. Disconnect the pressure hose from the elbow (35 and 36 in
Hydraulic System parts list) on the back of the hydraulic
pump.
2. Remove the two mounting screws and two lock washers
(10 and 11 in Main Assembly parts list) that attach the
motor/pump assembly to the cart.
3. Place the motor/pump assembly in a vise, holding it
securely by the motor/pump block (31).
4. Remove cylinder head plug (1).
5. Loosen lock ring (28) with a spanner wrench and unthread
tube retaining nut on tee (24). Loosen tube retaining
nut on elbow (22). Slide the nut down. Push motor tube
(23) into tee (24) far enough to clear elbow (22). Slowly
unthread cylinder head (8) and Iift it just high enough
above the cylinder (29) to reach the valve rod assembly
(18) with vise grip pliers.
6. The piston rod (19) should be near the top of its stroke for
disassembly. It may be necessary to use a wood or nylon
driver to push the piston rod up to its top position.
