Disassembly

(Item 24) mounting the pump to the pump mount and
remove the pump.

Put plugs in the pump ports. Put covers on the fittings.
Reassembly
IMPORTANT: When disassembling hydraulic lines
make sure hydraulic plugs are placed in the open
end of the hydraulic line to prevent debris from
contaminating hydraulic fluid. It is also a good idea
to tag hydraulic lines when disassembling so that
they can be properly reassembled. Keep all hydrau-
lic and suction lines clean and free from debris.
During replacement avoid overtightening fittings
(see the Hydraulic Hose and Fitting Information
section of this chapter). Check hydraulic lines for
breaks or cracks. Check the hydraulic reservoir for
proper fluid level after replacement of any large
component.
1. Fill pump with clean hydraulic fluid and cap fittings.
2. Assemble the pump to the engine in reverse of the
disassembly procedures. Check all lines for clearance
from the frame and other components.
3. Start machine and check for proper performance.
