Something Failed, let’s find it! Transmission Analysis.

Semi stuck:

They didn’t have the second tool, the one you hold the flywheel in place with. Any ideas?


It’s pressed onto a taper using 120nm during installation. I’m hesitant to lever anything against the cases as they’re thin cast aluminum and $4,500 if you break them...

USUALLY a simply sprag plate will be ample. Or you could get a "beefy" mate to simply stop it rotating. And of course there is the tweak/light tap method.

I use 2 large pins that normally lock the legs of my engine crane in place. You'll see the wheel has 2 different bore sizes so you should find something that'll fit. Stick the pins in adjacent holes then i wedge a pry bar or *** off big screw driver between the 2 pins. Hold your mouth right and press go on your rattle gun

P.s. i assumed you were using a rattle gun....good luck if you're trying with a breaker bar or similar!

P.p.s. getting back on is actually the fun part...you may lose a finger or 2 if your not careful

If you do end up tapping on the center bolt, use caution, as you can shock the magnets and weaken them.

B-King!!!!!!!!!!!!!!!!!!!
YES!!!!!!!!!!!!!!!!!!!!!!

I love this forum...always learning...I didn’t realize Burger King made bikes...

Yep Hold the fly wheel and tighten the bolt as much as you can. The other tool is just a pin spanner that goes in the holes on the end so you do not damage the OD. You can whip something up quick. After snugging the bolt as much as you can give the head of the bolt a good rap with a 32 oz hammer or better (it's the shock that releases it from the taper). Much like releasing taper drive tools in the machinist field. (Morse, , Jarno, and Brown & Sharpe) Otherwise I bet you'll destroy the female threads just trying to use the two tools. There is a Woodruff key in the shaft: * keep track of it *. Also most people miss the bolt hidden by the oil pressure pump. Pull it before you spilt her open then you'll see the bolt.

Your 120 nm is enough just give her a shock with the hammer. She will jump off the shaft quicker then stink on crap. You'll be laughing when its over.

That my friend is why we have redundency ! Although I don't understand the reason we have (1) old fellow, and (2) bollocks. 16 of the latter are off no consequence without the former

Thanks all.

Will hit it later on (it’s 5 am).

I tapped gently last night on the bolt but on previous motors I’ve done I was told explicitly not to tap on the crank pulley very hard, something about side load on a bearing or whatever.

I’m sure it was vehicle specific, so I’ll get this done yaay.

PS: I only use hand tools, no electric or air.
