I replaced the countershaft seal after I would find an occasional drip on the floor, I'm now getting more drips.

I used a new Yamaha seal and collar, the shaft has no play side to side and rotates true.

The collar didn't feel super snug against the seal, but it did have contact friction, but very slight.

Is the Yamahe brand the only seal avail, maybe it was a damaged seal, not sure.

Curious to any thoughts on this.

 

Not sure what you mean by countershaft. If it is the seal behind the engine sprocket, I did one a couple of months ago and am fairly sure the leak wasn't the seal itself, but the housing gasket. I replaced both and no drips since then. The collar 90387-251W4-00 that runs against the seal needs to be fairly good, a big groove worn in it could cause a leak, and I'm not altogether sure what stops oil from coming out between collar and shaft.

 

Thanks,

Yes, I should have added that lthe leak is behind the drive sprocket.

I did not replace the housing gasket the first time, but I will this time.

Curious also to what the torque spec is on the drive sprocket nut? I called around and was given a few different responses, the consensus seems to be about 70 foot pounds, but nothing concrete.

 

I probably rattled it up with the air wrench, it won't be all that critical, with the lock washer to keep it from moving. As you slide the seal and housing onto the collar, check that the lip doesn't curl over. Some seals are prone to this and I think that is one of them.
