Flywheel OFF

[vmaxcruzer]

Well my friends I gotta tell ya this is one of the toughest flywheel removals EVER!!
I used everything, engine on its side, (flywheel up) penetrating oil, lots of heat, a 550 inch lb gun, voodoo...Nothing. I broke my dead blow hammer.
I sat back and stared at this thing, fantasizing about finding the guy that installed it and kick his balls up into his stomach.


As I was...I dug out my 20 inch adjustable wrench and a big breaker bar, put the wrench against my hip and pulled HARD, several times till it wouldn't give anymore. Nothing! I even peed a little once on a pull. I figured something was gonna break so I resorted to mind power. As I sat there staring at this damn thing for a good while out of no where it POPPED, jumped up about 5 inches, scared the shit out of me. That was the second time I peed.


So...its off, and the best part is that the teeth on the start gear are perfect, not a scratch or wear mark one. Also the start clutch looks good too, No wear that I could see, three bearings, springs and caps are new looking but the three bolts were about a half turn loose.
I have no problem replacing something (especially this hard to get to) just to be sure but these parts look fine. I see that the factory used a punch to keep the bolts from backing so I'm thinking some red lock tight will do the trick unless someone has a better idea.

Good I'm glad to see it worked. I skyped my bro, Moogly and he said he would hook you up for a fee. umm, so don't be too suprised if you have a little testicular shrinkage in the next few days :rofl_200:

:rofl_200: My first one did the same thing! The bike was on a lift. It ended up bouncing around on the floor... got all beat up and put a big old dent on the flange.

I must get around to putting up a detailed 3d modelled drawing of the puller I made and share with all.
Unless I just had tin a$$ luck and the fly wheels I pulled were never that tight but it has been very easy to get them off so far.
Mine works on a different principle whereby there is no squashing of the central thread which I believe is counter-productive as energy is wasted on the mashing on the face of the crank snout versus the puller's central shaft/boss.

 

[TURBOVMAX]

Their not all like that and usually they come off fairly easy. Just once in a while the fit must be near perfect. I always lay old blanket out now just in case.

 

[vmaxcruzer]

Just making sure, you guys are using the red lock tight not the blue?

 

[TURBOVMAX]

I use the blue... the red is permanent.

 

[vmaxcruzer]

How much is needed to release the blue? More than the heat of the engine?

 

[TURBOVMAX]

Here's the spec LOCTITE 242

 

[TURBOVMAX]

Most people don't use the product properly. You should spray the fastener and female threads down with a solvent like brakleen to remove the oil. If they did that with the red they would be sorry they used it when they went to disassemble the next time.

 

[vmaxcruzer]

Blue it is.:biglaugh:

I cant absolutly agree with using anaerobic glue to lock the flywheel bolt.

One, Yama do not use it becouse trully, bolt is not most important element with holding the flywheel.

Second, that next time when you want to remove the flywheel its give you a hell to remove it and dryed glue chips will goes to your lubrication system.

Three, its not nessecery, completly unecessery.

They are not talking about that. They are referring to the 3 x starter clutch bolts which Mr Yamaha stupidly peened over the ends of the threads, which just happen to come loose :bang head:
Using Loctite will hopefully prevent this from reoccurring .

Yup....if applied properly red locktite = forever

300-400'C and it will let go(checked) but what will be damaged by this i dunno :confused2:
