Gentlemen, I am about to change my camshaft and have removed the top of the engine - now, in order to remove the timing cover I want to loosen the crankshaft pulley bolt. How do I do that so the crank does not turn. - Awaiting your answer with oily fingers... chris varming
 
can you not just put the car in gear so yhat you are working abainst the weight of the car and get a spanner on the nut pull as far as you can and then persuade with a lump persuader , cover the rad with cardboard if its still in so you dont accidentally tap into it.or am i just a philistine,rich
 
Hi Rover100rich - I am working against a torque of about 140 lb/ft - I thought of slipping a spanner in between the lobes of the old camshaft, but thought better of it as the cylinder block is made of aluminium.... there must be another way... chris
 
I think Rich has the right idea with the car in gear but you probably need a very long bar (ie a couple of feet) to overcome that sort of torque.

If you haven't dismantled too much of the engine, one method is to use a socket and decent length power bar. Brace the power bar against the ground or chassis and flick the starter.
A more 'correct' method is to remove the lower bellhousing cover and secure the flexplate to the bellhousing using a metal strap from one of the torque converter bolts, then you can use your power bar on the crank pulley.
However, I have found that most of the V8s I've worked on aren't actually that tight and the bolt can be undone by using a smaller (12") power bar and smacking it with a mallet.
Access shouldn't be a problem because the radiator has to come out to change the camshaft anyway. I presume you don't have access to an impact gun?
 
Well the idea about setting the car in gear is not an option, I have an automtic BW 65 gearbox and I do not have an impact gun. I guess that in order to secure the crankshaft I have to take off the sump and use a bar as a jammer? any other ideas?? Chris

As above but leave a space between the bar and the chassis/floor and when you flick the starter the sudden stop undoes them every time.
 
is it possible to wrap rope or webbing strap around the pulley then secure the end so as you pull against it it tightens up , then thump it, good luck rich
 
mine came undone with the breaker bar when i forgot it was still attached and then tried to start the engine... :roll:
 
I finally managed to get the bugger off, applying the "correct"method suggested by KiwiRover - thanks for your participation in my pulley-problem. Chris+++
