Cankshaft removal help needed (Poorboy Conversion.)

Post by patbrandon1 »



Anyone that has done a Poorboy conversion on a 1200, could you please tell me how the %$#&* you got the crank shaft bolt out? :?: :?: :?:

I am stumped, tired, and a bit frustrated. :(

Any ideas could be worth a dozen cookies. :D

Thanks for your time.

Bike in 3rd or 4th, or even 5th gear, a big stick through wheel spoke under mufflers, socket on bolt, 1/2" breaker bar, back it out CC. Rear wheel will turn backwards until stick is stopped by mufflers, bike in higher gear = engine output shaft has low torque multiplication.

Thanks Crystal Pistol. Just to be sure. I back it out counter clockwise, is that correct? I was not sure after it was not breaking loose. I had read that they are standard righty tighty, lefty losey, bolts, but didn't want to break that bolt.

Is it pretty hard to snap that crank bolt?
I just am a bit nervous.

I might go out and try it again tonight.

Was on my '85 GL1200. Yeah, it's tight … use a torque wrench putting it back, I forget torque value.

Thanks for getting back so quick.
Torque spec is 55 ft. pounds.
So you don't think I'll break that bolt?

Not as long as your pulling it C C … or to your left facing the bolt head. 55 ft lbs is "gootentight" territory. It has to be tight though because of engine rotation.

I used an impact gun for removing the bolt. Put bike in gear and had a friend step on the rear brake. The bolt came out with out a problem. Use blue loctite and a torque wrench when re installing the bolt.

Yeah, :D Excellent way to do it … if you have a friend and an impact gun handy. I didn't know if he had them handy. I think the impact gun alone would do it … even without the friend.

Yeah!!! :D

I got it off without breaking the bolt at 11:37 p.m. last night. :D

I used Crystal Pistol's idea of the board between the spokes, and a half inch breaker bar with a 2 foot cheater bar. It actually came off easier than expected with no dents to the mufflers once the wheel stopped turning. :!:

My brother has a high impact cordless that he said would surely do it. But he lives 38 miles away and I thought I would give it one more go before I went and borrowed his Dewalt.

Thanks everyone, especially CP for all your help. Cookies for everyone. I gotta see if my girl will cook them for you because if I did, they would suck.

Peace, and ride safe.

Yeah, the DeWalt would have done it with good battery charge.

Glad you got it resolved. :) I knew the mufflers would stop the board unless they were about rusted away. :roll:

Please, enjoy the cookies … I get too many now anyway, but Thanks. ;)
