    Why won't my Tulsa Winches hold the load?
    • J
      Jennifer CastroAug 6, 2025
      If your Tulsa Winches won't hold a load, there are several potential causes. It could be due to excessive back pressure in the system; if this is the case, check the system for restrictions and reduce the backpressure. Alternatively, the brake discs may be worn out, requiring replacement. Lastly, the winch clutch might be slipping, so inspect the clutch and driver for wear and replace any worn parts.

    What to do if my Tulsa Winches will not raise the load it should?
    • N
      Nicholas HillAug 11, 2025
      If your Tulsa Winches won't raise the load it should, the relief valve setting may be too low to allow proper lifting; increase the relief valve pressure setting, but do not exceed recommended system pressures. It's also possible that the load being lifted is more than the winch’s rating; reduce the load or re-rig to increase mechanical advantage.

    Why do Tulsa RUFNEK 130 run too slow?
    • M
      matthew90Aug 17, 2025
      If your Tulsa Winches run too slow, it could be due to a low flow rate. Check the flow rate and increase it if necessary. Another possibility is that the hydraulic motor is worn out, requiring replacement.

    What to do if Tulsa RUFNEK 130 have oil leaks from the vent on top of the gearbox?
    • M
      melissa78Aug 23, 2025
      If oil leaks from the vent located on the top of the gearbox of your Tulsa Winches, the motor shaft seal may have failed; replace this seal and reduce backpressure if that caused the shaft seal to fail. Another potential cause is that the brake piston seals may have failed; in this case, service the brake section and replace worn parts.

    How to fix a Tulsa Winches cable drum that won’t free spool?
    • E
      Erica WoodAug 29, 2025
      If the cable drum on your Tulsa Winches won’t free spool, it could be because the winch is not mounted squarely. Check the mounting and confirm that the winch is mounted on a level surface. Alternatively, the clutch may not be disengaged; disengage the clutch.
