OVERHAUL

If a tool is performing poorly or leaking badly, a complete overhaul may be necessary. Service Kit

585001 Contains a complete set of o'rings, back-up rings and screws.

Perform overhaul in a clean, well lit area using care not to scratch or nick any smooth surface that

comes in contact with an o'ring. Use of Lubriplate® (Gage Bilt part no. 402723) or other lubricant

is recommended during reassembly to prevent tearing or distorting of o'rings.

Disconnect hydraulic hoses and electrical cord from powerunit. Remove couplers (585037) from

hoses (505034) and drain. Remove retaining sleeve (505024) and split ring set (585002) and

remove nose assembly. Push piston (585123) back into cylinder (585204) to empty all fluid from

tool.

Unscrew button head cap screw (400047) from cylinder cap (585226). Using cylinder cap wrench

(585001) remove cylinder cap (585226). Push piston (585123) out rear of tool remove relief valve

(585023). Remove retaining ring (401521) push adapter (585105) out the rear of cylinder. Using

ejector gland wrench (750033) unscrew ejector gland assembly (762006) from piston and remove

pintail ejector (505022). Using a small blunt object, remove o'rings, back-up rings and quad ring

from components.

Remove socket head cap screw (404128 & 401218) from handle (480127) and unscrew hydraulic

hoses from cylinder.

Clean parts in mineral spirits or other o'ring compatible solvent being sure to clean o'ring grooves.

Inspect components for scoring, excessive wear or damage.

Reassembly sequence is opposite of disassembly. Be sure relative positions of o'rings and back-up

rings are as shown in exploded view and part list. Relief valve must be installed with four flats

towards the rear of the cylinder. When installing cylinder cap (585226) make sure flats on cylinder

cap (585226) and flats on cylinder (585204) line up flush so locator (586124) will sit level between

cap and cylinder. Coat hose fitting threads with a non-hardening Teflon thread compound such as

Slic-tite® (Gage Bilt part no. 403237).

DO NOT USE TEFLON TAPE.
