Pully removal
« on: July 10, 2007, 21:27:26 »
I have just fitted a 200 disco engine to my 90. I need to change the cam belt as I don't know the history.

I have been trying for three hours to get the bottom pulley off (crank shaft)
It just wont come off. Am I missing something or do you just take off the big bolt and then pull it off.

I have tried using a puller, heat and lots of penetrating oil.

Any ideas?

Should be just the big bolt in the center.
Have you tried the puller and heat at the same time. Someone might have put a bit of locktite on !!!!

heat on the end of the crank??? is that advisable considering how well heat travels?

if the bolts off and it wont budge with a puller then its been loctited on
when i take them off i apply pressure with the puller
warm it up rapidly with the bottle and give it a sharp belt with a bar and lump hammer
usualy sorts the job out

Leave the puller on over night under load.

Recon someone used loctite on the shaft instead of just the thread!

Mine fell off once i got the bolt out, but that took hours over 3 days!!

Good luck, but pressure over night seems a good idea as opposed to heat, as it might just crack it open if left over night.

buy your self a new pulley, and cut the old one off.
not worth knackering the crank with too much heat.

bad idea  :roll: i wouldnt do that....dry or locktight is best
the aux belts are only run off half a woodruf key, thats why locktight is put on
i personaly locktight mine as i dont want another broken crank again and spend all weekend repairing my engine  :roll:
its alot of pressure over a very small key
