Crank pulley (again - sorry!) - Advice needed

You can do this a number of ways. I'd personally leave the crank bolt in to wind the centre bolt of your tool against, not the crank nose itself, just to protect from damage.

 

Or If you leave the crank bolt a bit proud you can clamp your tool down on it with the two thin bolts through the pulley, then from above with a 22mm spanner unwind the crank bolt and this will draw off the pulley.

 

If it spins you should be able to just hold it with your hands, like most jobs if it seems nothing is moving with excessive force just step back in case you are doing something stupid!

Mate, very helpful advice :thumbs:

 

I did the first thing you suggested, put the crank pulley bolt back in and wound the tool against that and it came off sweet as!! You've been a lifesaver, already got the new pulley on now. One final question, my pulley has 2 timing marks, white and yellow, which should I line up with 0?

 

Cheers,

It only goes on in one position ie over the key way, the pulley has a notch/groove on the outer rim that is the timing mark I believe, cams have marks that line up with lumps on the cams back plate.

 

It has two grooves, one white and one yellow. I've got the pulley on the crank over the woodruff key, should I get the cam covers off for setting tdc??

 

I don't know if the white mark needs to be aligned or the yellow

Sorry I didn't think you'd touched the cambelt!

 

I haven't, have I done something wrong here? In the process of the various attempts to get the crank bolt off, the pulley has turned a few times (before I bought the proper SST) so the pulley wasn't aligned to TDC by the time I took it off, is this going to be an issue?

 

Thanks for letting me know which colour to go for Chris!

No issue, it won't matter as the crank pulley itself doesn't effect any timing, when it's been turning the belt and cams have been turning as normal around the little crank pulley behind all the plastic covers.

 

Basically nothing you've done can have put it out of time, by putting the pulley on the key way you will be putting it back exactly as you took it off.
