nissbird: DISASTER! (Montag 6. Oktober 2014, 20:16)

Oh no shitty news, my bulldog will not shed it's flywheel!
Having tried removing it myself and failing I gave it to a really good garage to remove the offending article, only for them to contact me later and tell me they could not get it off either. They put it back together and replaced the oil without any charge, the guy at D & R Motorcycles Hereford was quite "put out" that he couldn't remove it.
Now the only way to get it off without destroying the end of the crankshaft is to cut it out.
I can still ride it until the starter clutch finally gives way but I am gutted.

Hey Phil,
bad news ...
We got a similar case lately in this board:
Demontage Polrad

It's an entry in german, but maybe you like to get the 7th topic (by TR1.Maschinfahrer) translated.
I'm sorry I don't know anything about working on motors ... but maybe the description is sufficient to help you / your mechanic ...

Thanks Wulldee,

The items mentioned in that post have all been tried to the point of destroying the end of the crankshaft.

Do you know anyone who might have a flywheel for sale? I could have the old one cut off?

Regards
Philip

WullDee: Re: DISASTER! (Montag 6. Oktober 2014, 21:37)

Hi Phil,
are these the desired parts?
Flywheel 129€
Flywheel 200€
Unfortunately I don't know whether a member of the board has one to sell ...

nissbird: Re: DISASTER! (Montag 6. Oktober 2014, 21:57)

Yes they are the right items, I shall discuss with the garage about cutting the old one off and then buy a second hand flywheel, if you could ask some of our friends in Germany I would be very grateful.
Regards
Philip

Philip

Sorry to hear about your woes, the dog's engine is generally pretty well bullet proof and mine has sat at 6,800rpm for miles trying not to lose sight an FJ1300, 1200 Bandit and BMW 1200 when we went to Italy.

You know of course that thr Bulldog shares its motor with the Dragstar so it might be worth doing a trawl to see if there is a Dragstar bottom end on the cheap.

See you for Treffen 12? The Wales jaunt didn't happen and the weather is moving against us now so looking like 2015 for a long run.

Good luck with the motor.

Cheers

Ade

Now the only way to get it off without destroying the end of the crankshaft is to cut it out.
Did they already try to heat the flywheel in the immediate vicinity of the fitting with a acetylene-oxygen torch while applying force with the puller (and of course tap on the central bolt of the puller with a hammer)?
Making use of a strong thermal gradient is often a solution for "difficult" situations.
Most of the time applying a small (but intense) amount of heat is enough (without burning something).

A Mini-Ductor is flameless, does most of the time not belong to the "standard" equipment, and would heat the crankshaft instead of the flywheel. But probably the videos will show what (intense) heat can do...

Almost given.

..and it´s too small to fit over the flywheel..

In the German part we have another suggestion : use "Ice-Spray" on the end of the crank...then give it - the flywheel.. - a healthy whack with a copper-hammer and it should pop off...it should..

Keep us posted
