Hi Everyone
As soon as the two studs show up I plan on putting my motor back together and shortly after that it will be going back on the frame. I would like some advice on the best practice for sealing the mating surface of the upper and lower cases. When I separated them yesterday there was only a very thin membrane of any sealer remaining. There were several goof ups by whoever put this motor together last so I don't want to just go by what I found when I took it apart.
I would like to know is which type of sealer is recommended and which areas of the mating surfaces need it, for example the mating surface behind the wet clutch doesn't need sealer because there is motor oil on both sides. I know this is pretty basic stuff to some of you but I don't mind asking because I want to do it right.
Thanks
Steve
Sealing up the case Question
Re: Sealing up the case QuestionHonda Bond 4 or Yamaha Bond 4 are what you want to use.
I apply it to ALL contact surfaces as you may find a area that a stud passes through and may need sealant. Like the area of the 2 studs you are replacing. Keep it thin but even. BTW Do Not Use RTV !. ..................lm
Make sure the mating surfaces are free of oil and there are no burrs that would prevent good contact all around. I use a small flux brush to dab as thin a layer as possible on both the top and bottom case surfaces everywhere they contact. Even the clutch side. Don't forget the two points in the interior where the two studs penetrate the top case. If you happen to slop any in an oil passage, just wipe it out. There's a tightening pattern in the shop manual that probably should be followed.
What is that?. ....lm
Hondabond HT, does the picture not show up? "For use in applications not requiring solid gaskets"
