Thread: Crankshaft bolt

Just a hint, tightening a crank bolt is best done in 4th gear, reduces loading on the hand brake and gearbox.

Hmm, someone in Melbourne will have the right tool that bolts to the harmonic balancer to do that crank bolt up.
It might cost a beer or three for the use

You don't want that bolt coming loose and wrecking the nose of the crank, then it gets exxy.

The 80Nm + 90* is bloody tight, you need a 3/4" drive socket and bar to do it, I sheared a 1/2" Snap On breaker bar attempting it.
(Ok, it had a 5' length of water pipe on it, but that's what is needed to get it to the right tension )

I wouldnt use a breaker bar... T bar for the win

I just put them in 4th and do them as tight as I can holding against the brakes. I put loctite 243 on the bolt and on the shaft as well to lock the balancer. Done dads car 3 times now, and its never come loose. It's up around 300k on the clock.

I use one of these...
