Hydraulic System: Service and Repairs
A case drain exists in the piston pump/hydrostat and a suction port
is near the input shaft of the gear pump
gear pump is installed to the piston pump, make sure that the plugs
placed in either of these ports are removed. Failure to remove plugs
will cause excessive pressure in the piston pump and damage seals.
Also, before installing gear pump to piston pump, fill piston pump
housing with clean hydraulic fluid through case drain hole.
4. Remove the plugs that were placed in piston pump case drain and gear
pump suction port. Fill piston pump housing with clean hydraulic fluid through
case drain hole.
The gear pump suction fitting must be on the same side as the
trunnion of the piston pump.
5. Align gear teeth and slide gear pump input shaft into piston pump coupler.
Secure gear pump to piston pump with two (2) cap screws and flat washers.
6. Remove the caps and plugs from gear pump fittings and hoses. Using
labels placed during gear pump removal, properly connect hydraulic lines
to pump (see Installing Hydraulic Hoses and Tubes (O-Ring Face Seal
Fittings) (page 5–6)).
