OVERHAUL
If a tool is performing poorly or leaking, a complete overhaul may be necessary.
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 Lubriplate® #630
-
AA (Gage Bilt part no. 402723) or equivalent during reassembly to prevent tearing or distorting of o'rings.
1. Disconnect airline (704311) from manifold handle (744303
-
1).
2. Disconnect hydraulic hose (206119) from manifold handle (744303
-
1) and drain into a container.
3. Push piston rod (568104) rearward until remaining hydraulic oil is drained. Remove button head cap screw (402482) and stat
-
o
seal (S572). Remove retaining ring (400935) and push pin
-
swivel assembly (568122) out.
4.
Unscrew socket head cap screw (401198) from retainer (568119) using a spanner wrench to remove retaining ring.
5.
Pull cap
-
cylinder (568112) from rear of head cylinder (568108). Remove nose assembly.
6.
Push piston rod (568104) rearward until it, spring (568105) and head piston (568109) is out of head cylinder (568108).
7.
Remove all O
’
rings and Back
-
up rings. 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.
8. 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.
Coat hose fitting threads with a non
-
hardening Teflon® thread compound such as Slic
-
tite®. DO NOT USE TEFLON® TAPE.

WARNING
:
Only qualified and trained personnel shall perform overhaul.
WARNING
:
Personnel must read and understand all warnings and cautions.
WARNING
:
Tool must be maintained in a safe working condition at all times and examined on a daily basis for damage or
wear. Any repair must be done by qualified personnel trained on Gage Bilt procedures.
WARNING
:
Disconnect tool from its power source before performing overhaul. Severe personal injury may occur if power
source is not disconnected.
WARNING
:
Excessive contact with hydraulic oil and lubricants should be avoided (See safety data sheet documents for all
applicable materials)
.
WARNING
:
When operating, repairing or overhauling tool, wear approved eye protection. Do not look in front of tool or
rear of tool when installing fastener.
WARNING:
Ensure air hose is securely connected to avoid possible hose whipping (Air Actuated Tools only).
WARNING:
Depress actuator assembly
-
air (704130) and disconnect from air, with the piston in the rear position, before overhaul.
Severe personal injury may occur if air hose is not disconnected.
USE CAUTION
when forcing piston rod assembly
downward with head cylinder removed. Hydraulic oil will eject forcibly from handle assembly.
WARNING:
Use only Gage Bilt hydraulic hoses and couplings, or equivalent, rated for 10,000 psi. (689.5 bar) working pressure.
WARNING:
Ensure air hose is securely connected to avoid possible hose whipping (Air Actuated Tools only).
WARNING:
Do not dry cycle or actuate tool without fastener in place. Damage to the nose assembly could occur.
WARNING:
Incorrect stroke will damage the nose assembly.
Note:
•
Dispose of hydraulic oil in accordance with manufacture safety datasheet.
•
All tool materials are recyclable except rubber o
’
rings, seals and wipers.
•
Use of SERVICE KIT (722568), which contains a complete set of o'rings, back
-
up rings, screws, washers and gasket,
can achieve a complete overhaul.
