To replace the seals you have to completely disassemble the engine and split the case......Be sure you mark the position of your magneto befor removing it and when you reassemble the case make sure the mating surfaces are spotless and use either case cement or Loctite 415. I personally prefer the loctite.
Help With Crankcase Seals
Hello, I own a little Yamaha Bravo 250cc and the crankcase seals need to be replaced. I plan to replace the seals with a friend, but this will be my first time doing this, and I would appreciate some pointers on the best way to go about the repairs. If anyone can give me some brief steps on replacing the seals i would greatly appreciate it! Thanks!

You probably already know this but just incase... You will need several special tools . clutch puller, ring compresser, torque wrench and torque spec's , magneto puller and an impact gun come to mind. Make sure you have new gaskets for everything. Tip. If you can find a engine rebuild gasket kit for your sled it should have everything you need including the crank seals. They are ALOT cheaper than buying all individual gaskets.
One more thing, cleanliness is next to godliness. cant be to clean.

Thanks for the tips they should be helpful! I think I will be able to get ahold of all the tools needed, but I don't have the specs for the engine. Does anyone know if and where I can get these on the net? Thanks
