The main crank shaft nut, is it normal thread or left hand thread ? :headvswal

Normal thread (turn anti clockwise to undo) You do mean the one to get the pully off at the front of the engine?

Put car in 5th gear otherwise you'll just be turning the engine over manually.

was easy with my air gun :p

 

but yes, normal thread.

I take it your is an Auto :(

If it's really stuck, put a socket and strong bar on and wind the motor over until the bar is reasting on something solid such as the chassis or a piece of wood on the ground. Give the starter a quick flick and the bolt will undo. MAKE SURE THE ENGINE DOESN'T START. If you have a turbo timer, turn it off !!!

Engine is out of the car and on a engine stand, i thinks i might go buy an air gun, have allways wanted a good excuse to get one ?

or lock the flywheel up with a prybar or the like

try putting a oil filter removing belt around the pulley and use a brake bar and socket ion the pulley bolt, this worked for me on a auto with the engine in place :)

you forgot "don't come crying to me when it goes horribly, horribly wrong!!"

 

air gun all the way!

You have to have a level of "skill". I'd like to see you get your air gun in there with the radiator in place :)

think i'd rather spend the 5 minutes and a few quid on coolant to remove it than go the cowboy route ;)

Have you tried 'shocking it off' ? Hit the wreach with a lump hammer.

I know not really sensible but I'd have a go.

Do you think this will be ok ?

No mate these air rarchets arnt all that good to be honeset they tend to turn the hole handle around with really tight nuts and bolts and have been known to break and trap hands.You need a proper air gun mate.

this is what you want, as said - air ratchets are not suitable for this sort of thing. are bloody good for dissasembly work once the bolts been cracked off. but you tend to crack the nut/bolt undone 1st.

 

depending on how much you want to spend you may want to pay out for a more heavy duty one than above, Clarke aint that great TBH, but prob ok for the occasional home use :)

I will pop into the shop tomorrow and get one of them and the air ratchet as i can see that beign very handy.

Thanks Guys

another trick to get the pulley off when the engine is on a stand and you don't have an airgun:

 

remove 1 sparkplug and set the cylinder at it's lowest point.

Now fill the cylinder with a long piece of thick nylon rope (through the sparkplug hole) until the cylinderbore is full/filled with the rope.

 

The engine is now "seized" and you should now be able to loosen the crankpulley bolt

 

when done pull out the rope and put the sparkplug back.

It's not a cowboy route. I've seen it done (by more than 10 mechanics) / done it 1000's of times with out a problem. It always works even when the rattle guns fail.

Mine came off fairly easily using the belt wrapping technique described on ttzd. Get the old AC belt and do this with it.

 

it will destroy the belt, and probably the water pump too lol, bolt came out easily with only a 12" ratchet though.

Now that is a good plan ... :bow:

as long as the piston is on its compression stroke & not the exhaust!! LOL!
