Hi All,
We have a set of bearing assembly's from an IRD balancing machine that we are stripping down and replacing the bearings etc. We have hit a snag, We need to remove the collar in the picture.
as you can see we have had a good go, this disc should spin up the threads and free the plate below. which then gives us access to the bearings in this picture below.
the idea is that the bottom collar can spin and raise the height of the bearing assembly to allow for variations in the journals on a shaft. The two collars are connected with sellock pins. . and by some stroke of genius the threaded "Pin" in the middle of all this is welded in place at the bottom. Nothing to tragic but I would rather not do too much damage as a new assembly is a few grand.
Here is what i have tried up to now
Knocking the top collar round with a drift and a small hammer, then a big hammer.
using heat and the above method
trying to spin the bottom collar with a pin punch and scaffold bar (due to the Sellock Pins this should move the top collar)
I soaked it in Plus gas for the weekend and tried all the above this morning.
when I knock the Sellock Pins though the bottom collar will spin quite freely so It is defo the top of that is stuck, and properly stuck..
Ideas on a post card and in the best way to can describe (was on a stag do over the weekend).
