    Why is my Pullmaster H25 Other winch not producing line pull at maximum pressure?
    • R
      richard41Aug 3, 2025
      If your Pullmaster Other winch isn't producing the line pull at maximum pressure as specified, there might be several reasons: * The winch could be mounted on an uneven surface. * The cable sheaves or block purchase isn't turning freely. * There's damage or wear in the hydraulic motor. * There's excessive back pressure in the hydraulic system. * The relief valve may be set too low; check the specifications for maximum operating pressure.

    Why does the Pullmaster Other winch brake vibrate when lowering a load?
    • R
      robert10Aug 26, 2025
      If the brake on your Pullmaster Other winch vibrates when lowering a load, it may be because: * The pump is too slow; maintain normal operating speed when lowering a load. * The brake is running too hot due to a lack of or insufficient circulation flow. * The control valve has poor metering characteristics. * The brake plates or divider plates are damaged. * The over-running clutch connecting the motor shaft with the brake assembly is damaged. * Air is mixed with the hydraulic oil (foamy oil).

    Why does the brake on my Pullmaster H25 Other winch not hold?
    • D
      Donna CookeNov 17, 2025
      If the brake on your Pullmaster Other winch isn't holding, it could be due to: * Contamination in the hydraulic fluid, or lack of circulation flow in the brake housing, potentially damaging the brake plates or divider plates. * Contamination in the hydraulic fluid, causing the brake piston to seize in the brake housing. * Excessive back pressure in the return line, releasing the brake. * An incorrect control valve spool, trapping hydraulic pressure in the brake piston when the control valve handle is in neutral. * The wire rope being fastened to the incorrect cable anchor slot. * Damage to the sprag clutch, or wear/indentations on the surfaces where it engages on the motor drive shaft or connecting shaft. * If equipped with an external brake release option, improper plumbing...
