I finally, finally got that f!@#$%g rotor off!
« on: May 14, 2005, 04:01:48 AM »
Woohoo! As you're all no doubt aware, I've had the mother of all pains in the butt trying to remove the alternator rotor offa my beautiful CB750F2, to the point where Mike Rieck (the patron saint of all CB750 addicts) sent me a brand spanking new Honda rotor remover, only for it to remove the internal thread from the rotor, but the rotor was happy to stay put. Bastard!

Well I woke up this morning (just as well too!) and rang a buddy who owns a tool store to see if he had any decent quality 2 or 3 claw flywheel pullers in stock, he invited me to come take a look (but I had to supply the donuts) and eventually I settled on an evil looking US made 6 inch puller, which he loaned me for the weekend.

I got home and went straight out to the garage and attached the puller. I'd previously "centre drilled" the roror bolt for the tapered end of the centre bolt of the puller, so I greased the bolt a tad, and tightened it up, but the rotor was playing it's old games again, so I took out my "Gas Axe" (oxy/acetylen torch) and heated the centre of the rotors hub while it was under tension, and still nothing!

F*ck it, I turned up the gas and heated that rotor up until it was almost glowing red, then gave it a few wacks with my plastic mallet, and "BANG"! After several weeks and as many failed attempts, it was finally off! Oh happy day!

The rotor was too hot to touch for half an hour or so, in the meantime I ratted thru a box of spares and found an immaculate rotor and bolt, so I stripped and cleaned the starter clutch and replaced the three OEM screws with new high tensile items, then wiped a little anti-sieze compund ito the rotors internal taper, and refitted it onto the crank. I re-assembled the alternator cover/transmision cover, gear pedal, foot peg etc, gave it a kick in the guts, and it ran, with no starter clutch squeal like it had previously.

While I hope that I never experience this situation again, if I do, long before I get to the stage where I tear out the internal threads in the rotor I'll bin the Honda tool and use a monster 2 or 3 claw puller and a lot of heat. Job done. Cheers, Terry. ;D 
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Fire. The answer always involes fire.  You credit the puller, I know in my heart it was the " Fire Wrench"
These wonderful little birds are great flyers, delicious eating, excellent for training your hunting dog, and just fun to shoot,or stuff and keep around the house.  Bobwhites can be put with other types of Quail and have very large penis's.  Quail are very popular with the babes.

No Ben, there's no crank seal on that side (oil bathed alternator) but surprisingly, I touched the end of the crank once I removed the rotor, and although warm, it certainly wasn't hot. I'll bet it gets a lot hotter in normal operation.

Fire. The answer always involes fire. You credit the puller, I know in my heart it was the " Fire Wrench"

I take my hat off to your fire gods Terry, if it wasn't for them I'd be cursing the manaufacturers of that beautiful, evil looking 2 claw puller! Cheers, Terry. (the victor, enjoying the spoils of war)  ;D
