case sealer

[Raoul]

Just wondering if Hi-Temp (Red) RTV silicone gasket maker is ok to use when putting the case halves back together?

I wouldnt do it... Mine was put together with it before and it was a leaky mo-fo. I would use Yamabond just to be safe.

Good luck finding Yamabond. Every dealer I went to was out. you might have to use 3 bond. Do not use any auto parts store silicone. They aren't made for the tight fighting surface and can keep the case half's from sealing totally. If that happens you can get crank bearing failure.

use the red gel seal or threebond or you will be sorry.

The red hi-temp oil-resistant silicone works good. Been using it on every engine I've done for the last 5 years and never had a single one leak anywhere. I also use it on gasket surfaces if I don't have a good gasket. Put a small bead on both surfaces (clean) and when it dries, peel off the excess. If your cases are clean and you let it dry for 24hrs and set up good it will work fine.

Hondabond and yamabond is the same shit.. I'm not sure if they aren't making it either but it is the same if it's still arround

Yeah, I saw some Hondabond at the Honda shop today. I might go get some of that, because I hate my Yamaha dealer. I've already put my case halves together with the red stuff, but y'all got me worried, so I think I'm going to split them apart and use the right shit.

Thanks

Red stuff meaning gel seal or rtv? Cause gel seal is ok.

RTV sealant. I'm getting mixed reviews on this.

I would split it while you have it out and put the right stuff in it. Better to do it right then have to do it again from not using the right stuff the first time.

Same here. It works fine if you use it right. Of course yamaha is going to recommend that you use yamabond, they want to make money.

I would NEVER use RTV to seal a set of cases. That is not what it is designed for.

 

I would use threebond 1104:

 

 

Case Sealant Liquid Gasket TB1104

 

A synthetic rubber, that is a semi-drying, visco-elastic sealer which is resistant to oil, water, gasoline, and chemicals. Application areas include sealing transmission case covers, motorcycle cases, timing chain cases, side covers, 2-piece cylinders, clutch housing bolts and oil filter mounting

 

Or permatex Anerobic flange sealer:

Good choice. It would suck to have some type of leak (being oil or vacuum) to occur while your out on a trail.
