UC MK2* front idler pin extrication

[RichardT10829]

I finally got time to do my own carrier, first time in maybe two or so years.. I have started stripping down the drivers side running gear, all going well up to the point I went to remove my front idler wheel from the axle.

I struggled to get the castellated nut off, heat applied and it let go, only thing is it has taken the threads with it….I cannot underestimate the horror I was filled with when I saw what had happened… I have concluded that the nut has either dragged remains of the cotter pin into the threads (although I did check the hole was clear) or for some reason, maybe 70+ years in the weather has caused the threads to let go.

I can have the pin machined it isn’t a deal breaker, but my question is this, has anyone extricated a pin from the cast housing before ? If so what was the method ?

I can’t risk damaging the casting, that would be horrific.

Any advice or tales involving the process would be appreciated.

I presume they are shrink fitted and it’s a case of gentle heat on the cast to release the pin, but I want to check with you guys first.


Cheers
