PUMP CARTRIDGE TEST PROCEDURE
If the pumping element (pump cartridge) is suspected to be faulty, it may be desirable to
test the cartridge without running the hammer.
TOOLS REQUIRED:
6 mm Hex Key Wrench
Electric or air powered drill
Drive Shaft – NPK Part Number G025-5075
PROCEDURE:
1. Remove hydraulic motor (a58) from the
pump assembly (FZ).
2. Install a grease cartridge. (Make sure
flat seal is in place.)
3. Install driveshaft (t77) into drill motor
(t76). Couple opposite end of driveshaft
with the worm shaft (a55) of the pump
unit.
4. Turn worm shaft counterclockwise. If
grease is pumped out of grease delivery
port, pump cartridge is good. If grease
does not appear, replace the cartridge
(see “REPLACEMENT OF THE PUMP
CARTRIDGE”, next page.)
