Primary chain engine sprocket puller

Hi both Johns...... I was hoping someone would point me to a brand of puller that worked for them and recommend the size to buy. Have tried my local bike shop but he was unwilling to lend out and suggested contacting Mike Hemmings but he's miles away in Northampton. Two mates have loaned me various pullers of theirs but neither will fit. One 2 legged would only fit if I ground down the tips and sides and the 3 legged one is 150mm wide and just too big!! Willing to buy quality tool but which one!!!! Any advice !! Someone must have had a stuck on engine sprocket and found a solution without busting the alloy alternator basket!!

Norton made a 2legged puller specifically for this job,try Russel motors for one, I had the same problem, nothing worked, heavy pullers broke ,blowlamps,big hammers,a waste of time. I borrowed the norton tool which looks too small and simple to impress, however it worked like magic. Someone has a crate full of them i was told,try all the Norton suppliers but dont buy a commando tool. I did buy my own but can't remember where. Where do you live?.

Hi Robert

After checking out 4 sizes of gear pullers which my buddies had I opted to buy the Sealey 75 to 100mm one I previously mentioned. I had to grind down the ends and just use it as a two legged puller so that they would fit round the back of the sprocket without damaging the alternator housing and yipee one or two turns and the engine sprocket came out no bother. Now to drop the engine and gearbox out and break them down.

cheers
