Crankshaft Holder

Put the car in gear and the handbrake on should hold it. Failing that, you can remove one of the timing belt covers and put a spanner on one of the timng belt pulleys on the camshaft.

I've heard of people sticking a socket & handle on the crankshaft pulley bolt, bracing the handle against the chassis rail and giving the starter a quick flick but it's NOT recommended (and you MUST be sure that this will undo the bolt rather than doing it up tighter!)

Good luck, they can be stuck hard sometimes!

Hi,
an alternative method is locking the crank with a stout screw driver blade inserted into the ring gear and against the bell housing after either the starter motor or the lower flywheel cover is removed.

assuming you can get the crankshaft bolt undone, the pulley maybe one that is keyed and comes off by hand. Not knowing the engine specifically, a lot of japanese cambelt engines and i think is an isuzu engine, have a hand push fit between the pulley and the crank nose allowing it to come away relatively easily.
hope this helps.

michael.

Thanks guys several different ideas there I 'll see how it goes.

Another question though

How does one remove the Serpentine belt tensioner assy ?

Is it with an allen key at the pivot point or just the bolt holding the rolller?

thanks

Roger, perhaps a little late since it sounds like you were trying to do this job on the weekend just been, but here is some helpful information:
appears to be instructions from Isuzu workshop manual
and
a very detailed description (with photos) by someone with first-hand experience
