  • Thread Insert Repair
  • I need to repair some of the holes on the centre housing; mainly where the running boards were attached. I think the bolts loosened and the movement mounting and dismounting the tractor over the years wore the threads down. I repaired the first one today; first time I have ever done a thread repair with an insert. Is it OK to leave the thread insert long like it is in the photo?

  • Think about that Den. The effective "grip" is the length of the threads engaged with the housing. The exposed portion of the insert is not adding anything to that equation. It's just a heli-coil - all you have to do is nick the helix at the base of the exposed portion and it will fall off. A good pair of diagonal cutters will probably do the job.

  • It isn't going to hurt anything but I would cut it off. I'd also use a thread locker on the insert.

  • I used some red loctite I had on hand but it is old; does loctite go bad? I was wondering if I should get some new.

    How do I go about cutting it off?

  • If it was liquid the Loctite should be fine. If you have room I would attack with a 4" angle grinder and cutoff wheel.
