Pulley Bolt Not Long Enough For Crankshaft Pulley

[Kwyjibo]

Hey,

In the process of removing the crankshaft pulley but I'm having an issue with my harmonic balancer puller. Even with the puller flush against the balancer the bolt is not long enough. The only thing that is the right size to put in there is the crankshaft pulley bolt itself. Is it safe to thread this halfway in as I imagine once the crankshaft pulley has moved it will be much easier to get off. I'm just worried that the threads may be damaged if I do this.

Cheers,

Adrian

not sure i am 100% clear what you mean....but you need to have the crank bolt in but threaded about halfway off when you use the balancer puller so the puller's bolt has somethin to push against. make sure you have at least 3cm of thread still it the crank

Yeah sorry thats exactly what I mean't. I was worried about leaving it in though as I imagine its quite a bit of force pushing it and I didn't want to destroy the thread on the crankshaft bolt or what it screws into.

yeah it is fine, threads are amazingly strong even though they dont look that tough. it can literally hold tonnes of force.

as a rule of thumb always keep thread depth of at least the diameter of the bolt, this one is a big bolt so like I said keep in in 2-3 cms.

Cool, thanks for the help
