Line Bore Main Pivot Pin Bore.
Repair to main pivot pin bore on a Kinshofer 500lt KM622 clamshell grab bucket.
Line bore back to round, bore weld back to reclaim the bore to 70mm, line bore back out to 75mm and turn a sleeve on the lathe and friction / interference fit into bore.
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 fully guaranteed for 24 months.
