Hey all, I have a question for a 2006 Electra X 500. Should the magneto rotor be a bit of an animal to pull off? I have tried this already with a set of universal pullers with a couple of high tensile bolts through the holes in the rotor. The first attempt resulted in a HT bolt breaking off (?!?) and the second time I applied a heat gun to the rotor to expand it, cranked up the pullers and grew more and more apprehensive as I pulled and pulled. I eventually gave up... and yes, I have removed the locknut first. I was about to go off and buy the rotor puller tool 98035 from our hosts but am concerned there might be something funny going on as the tapered shaft means this should pop off quite easily no? Any help or advice would be much appreciated. Cheers.

If it is on a taper then I might just wind the the thing up real tight and whack the hex end of the bolt with an appropriate weight of thumping tool. Worked for me in non enfield applications

They are tight and as you say it is on a taper. When you have it under tension with the puller, give the center of the puller a hit with a hammer and it should pop off

Hmmm, 'hit it with a hammer' seems to be the advice for the day. This all sounds very scientific and professional... Still, they say the beauty of the bullet is you can fix anything with a swift kick so a hammer seems the next logical step

. I think I'll be buying the pullers then, might even treat myself to a new hammer...

Cheers all.

the hammer trick does not only belong to Enfields, pretty much anything on a taper shaft benefits from a tap on the end of the puller when it is under load to pop it free

Same reason an impact driver will free things you have no hope of getting loose any other way

I would use the proper puller. I've found it pops off easy enough with it.

Must admit Frank I have never had a problem getting them off with the puller I made

Just re-read - "and the second time I applied a heat gun to the rotor to expand it," ........ Heat & magnets are not really compatible are they?

Norm, that's as may be but I'm not sure what type of puller Knock's tried, whatever it doesn't sound too successful. By the sound of it it may be trying to pull it at an angle. The proper tool is threaded to fit the centre of the rotor and screwed in to apply force on the end of the crankshaft and will pull it straight. I must say though I found the T handle not man enough, or me not strong enough, to tighten it enough to pull it free so a spanner may be required to get enough force to release the rotor. I agree with Beezabryan, heating it is not a good idea for the reasons he states.
