EDGE
For general maintenance that requires high torque values and repeatable results, the Edge is HYTORC’s workhorse. The straightforward three-moving-part design was created by HYTORC over 30 years ago and has been consistently improved upon resulting in the most tried and tested line of hydraulic torque wrenches in the world.
01. SIMPLE OPERATION
The three-moving part design of the Edge series reduces the number of potential repairs and keeps operating costs to a minimum.


02. MULTI-AXIS SWIVEL
The multi-axis swivel is used on all HYTORC hydraulic torque wrenches (with the exception of the ICE series) for maximum positioning flexibility and safety.
03. PUSH-THROUGH DRIVE
For quick and simple directional changes and maximum durability, the Edge series features a push through square drive.

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
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.
