    I think I might even have a can of that! That won’t hurt circuit boards or resisters or solder and such? I was just going to wet a Q tip and gently wipe clean.

    Nope. Works good on circuit boards. You could just spray it on and wash the oil off the board.

    Cool thanks! :thumbsup:

    Just don't spray the board while it's hot...

    (Thermal stressing of the component's encapsulating plastics.)

    Roger that! I’ll be careful. :thumbsup:

  6. Hi, about sealing the oil leak around the counter sprocket.
    Once the sprocket is removed, does that spacer, or can that spacer also slide out?

    Did you put any Hylomar or Yamabond on either end of the spacer?
    Like this pic A?

    And you mentioned you put it on the sprocket. Directly on the back side of the counter sprocket?
    Like this pic B?

    Been ponderin' this. Spacer has a rubber seal on the outside, but nothing on the inside. Oil leak pathway seems to be between the inside face of the spacer and the outside face of the shaft bearings inner race. From there out to the sprocket and nut... which ain't gonna stop oil. The threads are just a spiral oil passageway. Mines not leaking, but if it starts, I'll put some sealant between the bearing inner race and the spacer.

    Another idea I have is to cut a slight bevel on the inside of the spacer with my lathe and put an o-ring between the inner bearing race and the spacer... Reason being is because I think it's also possible for oil to get past the shaft and inner bearing race. o-ring would squeeze down tight on the shaft and prevent that.

    I’m

    Well guys, it’s funny you bring this up again. I still have the leak, and I have been thinking about how I want to address it. As it is now, as soon as I get back from a ride. I get busy with a rag wiping off the underside.

    What I did was apply Yamabond on the back side of the sprocket and tighten the heck out of it.

    That sleeve spacer does come out. I probably need to pull it out and check to make sure all the mating surfaces are clean with no nicks. I will look into some of Jim’s ideas. Right now it’s on the back burner while I get my ‘77 going.

    I know I should try harder, but I tend to be a bit philosophical about tiny leaks. Most elderly folks have a bit of incontinence from time to time.

    It’s more than a little , unfortunately. If I don’t stay on top of it , it trashes my bike pretty quick.


    Jim , you were saying that you thought that spacer had a rubber face on the exterior. Here is my spacer from a few different angles. Mine is all metal.

    No, I meant that the spacer rides inside the case seal. Sorry for the confusion. The spacer is all metal.

    Oh, ok. Well when I get back to it, I’ll post up some photos and see what’s what.

    I like Jim's o-ring mod.
    Here's a pic of a countershaft, showing the span of smooth OD between the shoulder and sprocket splines. Some of that span would be occupied by the output bearing inner race. I would hope that there's sufficient remaining span for the o-ring, not wanting it to set atop the spline reliefs...

    Edit: This manual excerpt depiction shows the extent to which the splines pass thru the spacer. If that were to be believed, then the o-ring may be atop the spline reliefs...

    My thought is to have the o-ring just fat enough to fill the cavity made by the bevel.... letting the spacer "still" make hard contact against the bearing inner race, with the o-ring sandwiched in between. The bevel would compress it in against the shaft.
    Edit: OK... I see where you're going there Steve. I'll pull the spacer off a spare motor tomorrow and see what we have as far as smooth shaft past the inner race.

    Kawasaki uses a very thin oring behind the spacer to seal the shaft. You probably would not need a chamfer because the output shaft bearing should have a slight chamfer to it. The o-ring would push into that. Check out item 31. This is from a z1900 Should be able to find a VERY thin oring at a good ACE. Just try it

    Well, that’s an interesting approach. Cra-Z1 , did you have any trouble leaking at that point?
