Although hydraulic clutches require minimal adjustment, performance issues like slipping or harsh engagement may require inspection.

1. Measure clutch engagement pressure with a hydraulic pressure gauge. You’ll need to tee into the pressure test port.
2. Normal engagement pressure should be within factory specifications—typically around 250–300 PSI.
3. If pressure is low, inspect the regulator valve and pump gear.
4. Disassemble the clutch pack if symptoms of slipping or shuddering persist.
5. Inspect the clutch discs and steel plates for glazing, wear, or warping.
6. Replace all worn or heat-damaged parts with a clutch rebuild kit.
