Line Boring a worn bore on a  Kinshofer KM602 Clamshell Grab bucket

Repair to main pivot pin bore on a Kinshofer 500lt KM602 clamshell grab bucket.

Build up extensive bore damage / wear via welding, counter bore back to round and line bore to 80mm to accept a friction / interference fit sleeve we turned on the lathe.

This method ultimately means we can still retain the recessed V-ring dust seal seat / location to further enhance the longevity of the repair.

We have been repairing worn bores on Kinshofer grab buckets to this exact method for over 10 years and we have never had one back for repair post this method of bore repair.

All bore repairs on Kinshofer KM602 and KM622 grab buckets are guaranteed for 24 months.
