"Rope trick" for crankshaft pulleys. Any horror stories?

JD79 · Mar 29th, 2010, 13:16

Hi again all,

I'm setting up to replace my timing belt. Taking the crank pulley off should not be a hassle - I'm going to use a big breaker and the starter motor. Torquing the thing back on is what is giving me pause for thought.

The "rope trick" seems like it's worth a try. Almost everything I have read about it is positive. Has anyone on here had any bad experiences using it?

Hi

When I change the belt on mine, I take the starter motor out and use a length of angle which engages in the teeth. This is good for removal and refit.

many years back i was assisting a fitter to undo the nut on a fork lift truck crankshaft (large diesel engine )now this nut was about three inches across the flats.two of us and a bar could not budge it.we put a large socket on it and a through bar (1" drive socket set ) and cranked the engine over with the starter motor while,st holding the diesel pump stopper closed so she could not start.the sheer power of the starter onto the engine turned the nut off as soon as the through bar jammed against the rear of the truck.

you dont say which engine you have but if its the 2.9 6 cylinder then you dont have to take the pulley off at all

I would really recommend getting a crank locking tool from Volvo, thats if it is a redblock engine you have.
It makes things so easy and there is no danger of damaging anything.
Mine cost about £20 I think although it was a few years back now.

A good cordless impact driver will do the trick, on & off. More expensive than the Volvo locking tool, but then more usefull too.

You can borrow this tool from the club but I don't know whether you have to pay anything on top of the deposit.

It would be great to borrow the appropriate tool... unfortunately I'm halfway around the world in Australia. And as everyone knows, Australia is entirely peopled with criminals. So even if I did borrow the tool, it would get stolen pretty sharpish.

I have considered using an impact wrench, but it looks like it would be very hard to get the wrench lined up. Not much room between the crank pulley and the radiator fan. Has anyone else been able to fit one in there?

The removal should not be too hard. I've got a breaker bar (leverage socket/long wrench thingy) and a 4 foot length of steel pipe, so I can use the starter motor to remove it. I think I can kludge some way of tightening it up again, perhaps using some heavy duty luggage ratchet straps and a G-clamp. I'll let everyone know how I go
