Hydraulic Section Rebuild
The hydraulic section can be removed from the pump and rebuilt without
removing the pump from its mounting. Disassemble and assemble the
hydraulic section on a bench using a rubber mallet, arbor press, and
soft-jawed vise.
Preparation
1. Flush the hydraulic section with a compatible solvent.
2. Shut off and lock out the compressed air supply to the pump and relieve
the system fluid pressure.
3. Remove the coupling as described on page C 2-2.
4. Disconnect the siphon and high-pressure fluid hoses, and the air supply
hose from the air motor. Remove the circulation valve kit, if installed.
Removal
1. See Figure C 2-2. Remove the fasteners securing the upper housing (3)
to the pump mounting surface.
2. Have someone support the hydraulic section while you remove the three
hex nuts (16) from the air motor studs (15).
3. Lower the hydraulic section off the studs (15).
