I have tried to remove the key from my Petter A1 without success. I have only just acquired the engine so have soaked the lot in penatrating oil and hoping that will ease the problem. Thanx for the great ideas which are most helpful, I think I will manufacture the plate with puller bolts. I'll let you know how it goes.

Hi lads i tried everything to get the key out of the flywheel of a big crossley and couldnt so i went and bought some 29/9 welding rods (very expensive) but worth it. Get a length of 1" threaded bar and weld it to the end of the key using the 29/9 rods then get tubular bar to fit over the shaft and the key then get flat plate and put a hole in the centre then a nut and washer and tighten it up and it came out no problem at all and a quick rub on the grinding stone and the key was perfect..........

Hi Guys, i just welded a piece of threaded rod to the key so it extends over the edge of the shaft, then i slipped a pipe over the shaft and put a plate on the end, and a nut , i then just wound it out with the nut. regards Bob

I used this method the other day to get a broken key out of a Novo that was giving me a lot of grief it works very well.

Default Flywheel Key Removal

If a key has rusted away on the outside or been broken off, I've used a deep reach drill bit and drilled at low speed 50% of the key out. Then I constructed a simple metal cage to fit over the hub and spot welded it together and finally used a heavy hydraulic pullers and pulled the flywheel off the crank.

My crossley flywheel practically fell off, i cant get the other one off as a cast iron pulley has been graunched onto the shaft so am currently beating bits of that away

Default interesting revlation

Hi folks

i've been speaking to some of the guys at work about how we used to make/fit/remove keys, and soemthing interesing has come of it


after the keys were made and flattened, the head was rounded on the face that faces towards the flywheel hub, this allowed a gouge shaped wedge to be fitted in and it can then be brayed out without the taper slipping off, its apparently a very effective way of driving the key out, though i still like the dreadnaught key puller i made from 1/2" steel, works quite well.

i've got no pictures of this type of key in operation, but i will try and make a drawing

Paul
