How it works

  1. Bore the worn bosse out over sized
  2. Build the bosse up with a specialist rotary welder.
  3. Re-bore the bosse to suit the pin or bush to tolerances meeting or exceeding O.E.M standards.

We can carry out the complete job from strip down to rebuild, including press fitting new bushes with our portable presses.

We can also supply new hardened pins and a range of bushes including brass, bronze, hardened steel or specialist nylon to suit all your needs.
