For crankshaft on a 71 triumph 650. I want to run a belt drive with no cover do i use the same seal as earlier years? Thanks .

Yes, all you need the 1969 and before crank seal, but don't forget to plug the 3 little level holes to the right of the seal, those holes go right into the crank case.
One easy way to plug those holes is to use the same 3 little rivets that hold the Triumph patent badge on the cam cover.

Thanks once again Tony...

But you still have to vent the engine, the original idea was a one end threaded 90 degree fitting with a barb on the other and a hose threaded out through the vent on the back of the cases

Would that be from the plug behind the cylinders?

 

[Tony the torch]

MAP cycle has a real neat vent kit for the crank pin timing plug behind the cylinders that comes with the thread in fitting all the hose and a PCV valve that allows presure out and keeps vacuum in, it really makes the engine a lot more leak resistant.

Hey Tony- I was researching this earlier today using the search function on here and came across another thread where you mentioned the kit from MAP. I checked out their on line catalog, but couldn't find anything. Happen to know a part number? THANKS!
