OVERHAUL
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 must 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:
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 exceed the maximum relief
-
valve setting stated on the tool and manual.
WARNING:
Relief valve must be installed with four flats towards the rear of the cylinder.
CAUTION:
This tool is to be visually inspected daily for signs of oil / leakage. If oil is noticed, the tool should immediately
be removed from service and be overhauled. Failure could result in bodily injury, damage to tool and voided warranty.
NOTE: Check end cap (762220) to ensure no hydraulic oil is leaking from the threads. If hydraulic oil is present, the tool must be disconnected from
the power supply and evaluated for damaged seals. Failure to evaluate and replace damaged seals may result in oil forcefully ejecting
from the threads of the end cap towards the front of the tool resulting in injury and will void the warranty.
Caution:
When tightening or loosening hydraulic hoses, use a
9/16”
wrench or and adjustable wrench to hold the hydraulic fitting to
prevent the steel tube from twisting. Twisting the steel tube can cause premature failure at welded joint.
If a tool is performing poorly or leaking, a complete overhaul may be necessary.
Wrench (750150) (sold separately) is recommended for complete tool overhaul.
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® #630
-
AA (Gage Bilt part no. 402723) or equivalent during reassembly to prevent tearing or distorting of o'rings.
1. Disconnect control cord assembly (585034) / air line (750154) from power supply.
2. Disconnect hydraulic hose assembly (505034) from power supply.
3. Remove hydraulic coupler
-
male (585047) & hydraulic coupler
-
female (585038) from hydraulic hose assembly (505034) and
drain into a container.
4.
Remove retaining sleeve (505024), split ring set (585002) and nose assembly.
5.
Using wrench (750150), remove adapter (762129).
6.
Remove cap (762220) and push piston assembly (762114) rearward to expose rear piston (762217), remove retaining ring (A
-
1139)
from inside the rear piston (762217). Using a piece of tubing, push the rear piston (762217) down about 1 inch to expose the
retainer
-
piston (762018). Remove the retainer
-
piston (762018).
7.
Push front piston assembly (762114) out front of cylinder assembly (762022). Then remove the rear piston (762217).
8.
To remove hydraulic hose assembly (505034), remove hydraulic coupler
-
male (585047) & hydraulic coupler
-
female (585038), socket
head cap screws (762032), and wedge lock washer (A
-
1536), then slide handle (750255) off.
9.
Remove all O
’
rings, Back
-
up rings, Wipers, Polyseals and Glyd 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.
10. 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.
(
See hydraulic thread preparation pg.10).
Apply hot glue to wire connections of the electric actuator (240122) to ensure wires DO NOT contact each other or handle assembly.
(Electric actuated installation tool GB7624 only).
TOOL DISPOSAL
1.
When tool life is met, drain hydraulic oil from tool and dispose of the hydraulic oil in accordance with the safety datasheet.
2.
Disassemble tool and remove all rubber o
’
rings, seals, wipers and hydraulic hoses. All tool materials are recyclable except rubber
o
’
rings, seals, wipers and hydraulic hoses. Dispose of rubber materials in accordance with the material safety datasheet.
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 (762003), which contains a complete set of o'rings, back
-
up rings and screws, can achieve
a complete overhaul.
