What to do if Allied Systems Winches has low oil pressure?
- D
  David MeltonAug 22, 2025
  Low oil pressure in Allied Systems Winches can be caused by several factors. Check for leaking pressure hoses and fittings, replacing components as necessary, and ensure hoses aren't rubbing on gears or winch components. Also, check, clean, or replace the suction filter if it's clogged. If the oil brake is leaking internally, indicated by low brake pressure, repair as required. Clean and adjust the oil relief valve, replacing it if defective, especially if there's no pressure. Check its pressure with a gauge. Check the control valve spool travel. Check the pump pressure output after all other checks have been made. Replace the hydraulic pump if it's defective, indicated by pressure variation with engine RPM.

What to do if brake does not release on Allied Systems Winches?
- K
  Kelly JohnsonAug 25, 2025
  If the brake in your Allied Systems Winches does not release or the winch stalls during a low RPM shift, first refer to the 'Low Oil Pressure' troubleshooting section. Then, turn the modulator screw IN to release the brake earlier and increase the sequence differential if the pressure modulator is set too low. Check the accumulator system for correct leakdown time, leaking accumulator valve, leaks in accumulator lines, or damaged accumulators. Inspect the brake piston and piston housing cavity for damage, replacing if scored or broken, and always replace both seals when the brake is repaired. Finally, refer to the 'Low Forward or Reverse Clutch Pressure' troubleshooting section if there is low clutch pressure or low oil pump volume.

Why is oil brake slipping on Allied Systems Winches?
- K
  Kevin McguireAug 26, 2025
  If the oil brake is slipping or the drum is backspinning on a fast shift from neutral to forward on your Allied Systems Winches, check the required pressure to release the brake. If the pressure is too low, replace the friction discs and separator plates. Replace the belleville spring if it is broken.
