Crankcase pulley

Hi I am preparing a 300 tdi for a kit and decided to replace the timing belt. This requires the removal of the crankcase pulley which is held on by one big bolt which will not move. after a few enquiries I found out the way to do it and it works but it is a bit dodgy. Ask an assistant to hold a 27mm socket on the bolt with a length of wood and a heavy bar on the socket and press the starter so the bar cracks against the chassis and loosens the bolt! The crank turns clockwise so position the bar appropriately and take care. Radiator and pipes etc were removed. Cheers

been doing that for years, your right it is dodgy though, disable the engine ie cut the fuel off, disconect the fuel injection pump so it does accident start running though. altenatively also if you havnt got ramps put it in gear, get someone to put their foot on the brake. then undo the crankshaft bolt with a breaker bar from above.

Don't forget, when refitting the pulley you need to apply thread lock to the crank nose as well as the bolt. If not done, there is a risk that the pulley can work loose and damage the crank.
