Troubleshooting

Prior to testing hydraulic torque wrenches. A visual inspection should be done. The visual inspection should include.

Cracked, bent, or damaged couplers.
Swivel Assembly
- Cracked swivel block
- Loose swivel assembly
- Swivel post retaining ring is attached
Loose end cap
Cracked or damaged housing

When testing hydraulic torque wrenches. Make sure the pump functions correctly, and is set to 10,000 PSI before the tool is connected. Connect the tool to the hose, and test the tool using the pump remote. ADVANCE and RETRACT the tool several times. Make sure the tool functions properly and the pump pressure builds 10,000 PSI / 700 BAR in the ADVANCE position.

Tool does not ADVANCE or RETRACT. Check the following.

Couplers are loose or damaged.
- Tighten and/or replace couplers.
Ratchet
- Replace ratchet if the teeth are stripped, missing or damaged.
Drive pawl Assembly
- Check drive pawl springs for damage.
- Inspect drive pawl for damage.

Tool does not build 10,000 PSI in the ADVANCE position, and there are no external leaks. The tool has an internal leak. Internal leaks are located in two areas, the swivel assembly and the cylinder.

Swivel Assembly – Tool will not build over 2000 PSI
- Replace damaged swivel seals.
- Inspect swivel post for wear and/or damage.
- Inspect swivel block for damage.
Cylinder – Tool will not build over 6000 to 7000 PSI
- Check the piston and cylinder O-ring for wear and/or damage.
- Inspect the piston assembly for wear and /or damage.
- Inspect cylinder wall for excessive wear.

Tool has an external leak.

Swivel Assembly
- Bent or broken couplers.
- Worn and/or damaged seals.
- Cracked or damaged swivel block.
- Damaged swivel post.
Cylinder
- Worn and/or damaged seals.
- Loose end cap.
- Worn and /or damaged piston assembly.
- Damaged housing assembly.

The tool’s square drive rocks back and forth. Check the following.

Lever Assembly
- Lever mounting screws are too tight.
- Levers cracked and/or damaged.
Reaction Pawl Assembly
- Damaged reaction pawl spring.
- Damaged reaction pawl.
Ratchet
- Replace the ratchet if the teeth are stripped, missing or damaged.
