Crankcase sealant

[sehseh1]

I tore down my other mac yesterday for a complete cleaning. dose any body know what type of sealant is best for the crank case and oil tank. it appeared to be a clear silicone on this one. the last one i did had a reddish color silicone. i only opened the oil tank on that one but this one needed to come all apart and i know that the seal must be good on the crankcase.:greenchainsaw:

Permatex makes a Anaerobic Gasket Maker,
Fills gaps to .050" and cures to a solvent-resistant seal that will not tear or decay during service.

I use Permatex Ultra Copper. Have used this stuff on all the motors I have built since it came out. None of them leak. Including the blown Big Blocks.

I just used yamabond (made by yamaha) for a Mac 130 and it worked outstanding. I had tried like 3 other products and they all leaked from the gas/oil ... I've heard good things about permatex motoseal also, I just couldn't find it in my area.

Yamabond

Yamabond is the best you will find. It does a good job of sealing cases with two or three times the area of a saw CC. The light gray clor is also not to objectionable.

were is the best place to find yamabond

I use Dirko HT and have never had any issues. I have been told by many saw guys though that Yamabond is just as good if not better.

Yamabond 4 is what you want ... there are others but I've only used yamabond 4 (and know it works well) ... this stuff:

But yeah, as mentioned you can get it from a Yamaha dealer ... Same price, around 7 bucks.
