case sealer

what kind of sealer can i get at a auto parts store for the case halves ?
the starter clutch shortcut dosen't seem to work if the clutch is in three pieces

 

I'm gonna say go out and buy the Yama-bond stuff, I used it on my quad and never had a problem with it, not worth the risk of having to split the cases again to reseal :cry:

 

"the right stuff" is another good choice, it can be used for everything but head gaskets!

 

It used to be that YamaBond was the sole recommended sealant. Now, there's at least a half-dozen good ones.

"Indian Head" (Old School) or Permatex Spray (High-tech). Indian Head comes with a dabber-on brush ... the small bottle it comes in is a lifetime supply. You coat ... wait ... after it tacks-up nice, you push the halves together. It seals and holds.

I did my Virago starter so many times ... that I started sealing the cover with Permatex Copper Spray-A-Gasket. Only, I didn't spray it. I sprayed a whole lot of it into a Tuna-fish can, and used an artist-style brush to paint it on. Both mating surfaces got two coats. It never leaked.

 

Permatex is now producing the grey sealant that is similar to Yamabond. If in doubt, get the Yamabond, it is the right stuff for the job.

 

Are these products used in place of gaskets?

I just used the grey Permatex stuff. It's runny, but does a good job. There are no gaskets between the case halves. Yu have to put sealant on them. There is a warning in the manual to put sealant on the main bearing bolt bosses to help seal in oil pressure as well.

 

I just ordered a tube of Yamabond. Does this mean that your cases are back together Mac? How's the progress? I should have all the parts to get mine together this week. Can't wait!

The bike is back together and running. Took it for a short ride around the neighbourhood, need to charge the battery. I guess I timed the cams ok after all :lol: . Yet to see how it goes at full chat. No more starter grinding, thank God. Really had my fingers crossed that everything was back together ok. Had some marathon wrenching nights (I'd never make money as a bike tech). It helps if you put things back together in order, that way, you don't have to pull the battery box and airbox and surge tank out several times. I swear it shifts a LOT better. I think it had something to do with putting the steel clutch plates back in a certain way, but I might be out to lunch. Each steel plate has a very tiny "nib" on the inner circumference, which I tried to line up with the hole in the clutch basket. Don't know if it helped or not. Gave everything a good drink of oil before buttoning it up. The buzz at 3000 rpm is gone. Nice to know there's new rings in there, and all the crud is off of the piston crown and combustion chamber. I might even get a ride in before the snow falls! I even broke down and bought a torque wrench. It's a bit nerve-wracking putting on those last few lb/ft when it feels like it's already tight enough, but no bolts were stripped during the entire job. Overall, a bit of a nightmare without a shop to work in, but a job well done if I do say so myself.

 

C-O-N-G-R-A-T-U-L-A-T-I-O-N-S !!!

I know the midnight-oil and hot stove routine ... been there many times.

Do a nice running-in and be very, very proud of yourself !!

You deserve a standing ovation!

That's great Mac. I'm really happy for you. I hope things work out as well for me. I'm havign trouble with the shims on the shaft on the bottom part of the case. They stick out a little and keep the case from closing all the way. I can't decide how to keep them in place without letting them get folded over. Did you run into this problem?

Greg

 

Yes. You must remove the shims, assemble the case, then slide the shims and middle gear assembly in through the side (there's plenty of clearance). Otherwise, it will be an exercise in frustration, and your shims will end up more like wave washers.

 

Cool. Thanks for the info. I will try that.

Yamabond 4 is dead long live hondabond 4
after cleaning off all the old sealer, i just knew some chunks went in the upper case and the lower case had some dust and a few dead bugs, so what the heck....out came the garden hose a light squirt and some spray thru all the oil passages the blow it all out with 15lbs of air and it aint been so clean since it was in Japan
now the question does anyone use lubriplate assembly grease on the mains
or just oil ?

 

Oil does the trick. Just remember to PRIME the engine with oil before you kick it over. Leave the plugs out ... run the starter for 3 ... 10 second intervals -- to get the oil in the sump circulated a little bit, and into the top end, before exposing the engine to a thousand revs or so.

 

Congrats MAC!!! I'll echo Rick here, "You deserve a standing ovation!". I was able to reinstall with the shims in place, but it was a deal with the devil to do it and took for bloody ever!! I'd pull them in hindsight and install them later, saves time!

 

Thanks for the kind words.

Priming the engine is not a problem on the Turbo, as it cranks a lot before ever firing up. Nature of the beast as far as I can tell. I have a small oil leak to take care of, but I can report that my bike is running well enough to get me in trouble, as cresting a hill on a backroad last weekend presented me with a steep incline that turned almost immediately into a dirt road. Brown trousers time for a few seconds, as pulling it down from 180 km/h on dirt was a bit of an experience.
