How do i remove the crankshaft pulley!

(1/3) > >>

Yoshi:
Simple one really, undone the 4 bolts securing the pully to the engine but cant get the actual pulley off, cant stop the engine turning either, it says in the haynes manual to put handbrake on, diff lock low box, and first gear but its still going.

Am trying to replace a snapped timing belt you see

mickelson:
what vehicle / engine is it. Auto/ manual?

Les Henson:
Easiest way to to make a suitable puller. Just a thick bar with two 9mm holes in - 75mm apart, centre to centre. Screw the crank bolt in about half way and use two hi-tensile M8 coarse thread bolts through the holes and into two opposing holes that secured the pulley in place. The bar will press against the crank bolt and as you progressively tighten the two bolts they will draw the pulley body off the crank nose.

Yoshi:
Ok, we dont have the ability/funds/knowhow/materials to fabricate tools lol

Its a 200tdi manual

muck_truck:
what are you removing it for ?  to do a cam belt?

Doh, just read your post properly  :roll:

You should only need to take the center bolt out to remove the pulley when doing a cambelt.

if you cant stop the engine turning you can try undo the bolt another way.  Put the socket on a decent length breaker bar, make sure socket is well on the crank bolt and rest the breaker bar on the underside of the chassis rail (steering box side) then flick the starter motor, it should come undone and you can then remove it by hand.

i held onto the breaker bar when i did mine, but it may be recomended once the breaker bar is in place, close the bonnet before you flick the key incase the bar snaps.
