Long time lurker in need of some help please - I've managed to make a pigs ear of a SC pulley change and need to somehow recover the situation.
Long story short - I'm in the middle of doing various jobs in the engine bay (replacing gaskets, SC service, water pump, thermostat etc) on my R53. All was going swimmingly until I tried to use a recently bought pulley puller tool that was really tight - it said it was for the R53 but it required some hammering (!) to get over the pulley, either it was a badly made tool or wrong size.
Sadly, I hadn't read that it is recommended to screw a bolt (the same as the ground wire bolt in the engine bay) into the shaft first .. I now have a portion of the shaft gouged out in the middle and the thread is messed up so I can't screw it in to retry.
I'm now looking to re-tap the thread, get a bolt in and use another tool - however I don't know what the bolt size/thread is.
Anybody able to tell me what bolt size/thread the ground strap bolt is please?
Any help much appreciated!
