Troubleshooting

Damper feels stiff or difficult to move

Check for debris or corrosion around the eyelets. Ensure mounting bolts are not over-tightened, restricting movement. If stiffness persists, the damper may require replacement.

Trailer brakes not engaging smoothly

Inspect the damper's connection to the hitch and the brake rod. Ensure there is no binding or misalignment. The damper may be worn out and need replacement if internal failure is suspected.

Damper is leaking fluid

A leaking damper indicates internal seal failure. The damper must be replaced immediately as its effectiveness and safety are compromised.

Setup, Compatibility & Care Instructions

Compatibility:

This damper is specifically designed as a replacement for the ALKO 251S Trailer Coupling/Hitch. It is suitable for ALKO trailers utilizing the longer hitch variant, with a maximum towing weight of 2600 Kgs. Always verify that your existing hitch is an ALKO 251S model and check the trailer's maximum gross vehicle weight (GVW) before purchase.

Setup and Installation:

  1. Ensure the trailer is securely braked and chocked.
  2. Disconnect the trailer from the towing vehicle.
  3. Carefully remove the old damper by unfastening it from its mounting points (typically eyelets).
  4. Align the new damper's eyelets with the corresponding mounting points on the hitch.
  5. Secure the new damper using appropriate bolts and locking nuts (not supplied).
  6. Reconnect the trailer to the towing vehicle and test the brake system thoroughly in a safe, controlled environment.

Care:

  • Regularly inspect the damper for any signs of damage, leaks, or wear.
  • Keep the damper clean; remove dirt and debris that could impede its movement or cause corrosion.
  • Periodically check that mounting bolts are secure.
  • While the damper is sealed, avoid high-pressure washing directly at the unit.
