Crank Pulley removal TD

Hi all..

I really need to remove one later and dont have a puller...

I just wondered if I got a peice of steel and drilled two holes, and screwed it to the pulley via 2 ?M6 bolts, after putting a bolt and a nut between it and the crankshaft end..

If i tried to unscrew the nut from the bolt, it would force the steel plate outwards, and therefore the pulley off ?

What does everyone else use? a 'special' tool, or a legged puller?

Pulley is new style rubber cushioned type, there does not seem much room behind it, with the lower timing belt cover in the way etc

thanks
John

Can't speak for the soupburners, but the ones on the petrols I've struck have all just pulled off with the fingers.
They are held by a woodruff key.
I'm a big believer in using the large breaker bar with an extension and sitting it on the concrete floor and just hit the key to remove the bolt that holds it in and which is usually very tight.

hi alan, got the bolt off ok.. axle stand under a socket extension bar, as support, then i utililised part of my HD engine crane as a 1 meter 10 kg extension on the handle.. in the end i pushed with >? my little finger, and it undid

yes have tried the starter motor method before, very satisfying

can even feel the pulley moving from side to side a tiny bit so it's not on tight.. makes it even more frustrating...

Only once have I come across a pulley that did not want to come off with my fingers. In that instance, I used a two-legged bearing puller (very thin jaws) to get behind the pulley. It only needed a lttle persusation then. It was just like yours, it would waggle a bit under finger pressure but would not slide.

In that instance, there was a little corrosion on the crank nose. This could be a problem with the rubber harmonic balancer type pulleys as the inner part (that slides on the crank nose) is aluminium and therefor subject to dissimilar metal corrosion.
