Getting a trunion off.
Posted: Sun Mar 15, 2015 7:30 pm
Late last year I tried to get my left trunnion off to change it, but I found that the bolt that connects to the two lower wishbone swinging arms has siezed in its bush and won't come out, so I put it all back together for the time being.
I tried heavy persuasion with a big hammer on a drift onto the bolt shaft with a nut positioned flush with the end and I tried plus-gas all to no avail.
I can't see how heating would work as the siezed bit is in the centre of a rubber bush.
Not sure if I can get the lower arms off the chassis; though that looks the best possibility from my armchair. I think I can get the nut off so I possibly only need to undo from the chassis the wishbone that is held to the trunnion by the head of the bolt. Hopefully I will then be able to srew the trunion down until it coms off the vertical link.
Once 'on the bench' I will be able try try other creative methods of getting the bolt out.
Anybody else got any suggestions.. Other than make sure to put copperslip in there next time?
