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 (21) into its
top position.
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 (17
and 16 in Cart Assembly parts list) that attach the motor/pump
assembly to the cart.
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.
