Why tap it on, when a bolt that is 20mm longer than the crank bolt is all that is needed to start it and avoid stripping out crank threads, or doing some other damage??? Is that how they do them at Holden?
The guide I use states to torque the original bolt to 240ftlb, then break it free and insert the new bolt, which is torqued to 37ftlb, then tightened a further 140 degrees, to stretch it into the correct torque. I've only done around 15 of them but nothing has come loose yet.
cheers
i have no idea how holden does it!
an old techie from there showed me how to do it though
i dont like chasing bolts all day to fit one balancer if i got another ten cars to do i need to move my arse!~!
so ive worked out ways to do things on experience i have not either had these mess up or as a come back to the shop
i will note that a friend of mine has a different technique thats way quicker than mine
he oils the end of crank with air tool oil
heats inside of balancer with his gas torch so its warm too touch
smashes it on then puts old bolt in
ratlle gun till its lined up with other pulleys
then removes bolt and tourque sets new one
he does them in like 6 or 7 minutes depending on how lazy hes feeling
my way takes normally about 10 to 15 minutes
but i ananly line up the pulleys with a laser aligner
too me that seems rough just rattling it up instead of winding it in smoothly but
he hasnt had any come nack either WAIT LIES
he had one come back cause he pinched the crank seal into the pump housing
but on pulling it apart we found some metal wedged behind the balancer later proved to be
some chunks of spring washers off the becnch!~ that jackarse
anyway the settings i gave are the specification from a manual for this model car
the ve v8s use old bolt to push balancer on then new one too hold it in as you describe
but yeah you will need to be careful if using a hammer to TAP IT ON as stated be as gentle as possible to start it evenly
with the bolt
