Stuck Pulley

How do I get the pulley off my BnS 11hp engine?

I have made a jig to bolt into the 3 bolt holes and run a smaller bolt with a trapped nut (like a hub puller) but that hasn't worked.

Don't want to heat it because it damages the oil seal.

Any ideas?

If youre not willing to use heat youll need to cut it. A puller should have taken it off. Heat is your number one friend.

You can also try PBlaster by soaking the top and bottom of the pulley in it for a few days on end, then trying your puller again.

But really you want to use some torches and a puller.

The trick is to heat the pulley by itself. Avoid heating the shaft.

Is the pulley a dual stacked pulley, upper on drives the gearbox, lower pulley drives the cutting deck?

I just took the nut out from the centre, sprayed a load of WD40 on shaft and pulley, i then just ran the engine for a couple of minute and drove it up and down the road. I just took the belt off and the pulley dropped right out along with key.
