The spindle has had its drive dogs smashed off, it has been re-engineered and new drive dogs to specification have been produced.
When drive dogs have been worn they can be hard face welded to 62 Rockwell and re-machined as seen.
Worn drive dogs have been welded and ceramic bush replaced.
PSG are fortunate to be able to weld within the factory as we have our own in-house welding facility.
