main shaft seal 1986 1100

[jcd]

had a few problems with leaking main output shaft seal .

have put a new seal in but it looks like the collar is tighter on one side of the seal, tryed to measure it and it looks like half to 1 mm difference from one side to another.

mainshaft not sitting center?   it’s a new Suzuki seal taped in as far as it will go and collar is new also ???

Would sort of indicate the bearing behind is fubar'd if shaft not centralised?

[jcd]

bearing seems ok, mechanic thought it was ok. Has a slight movement. but then again why would it be closer to the bottom edge of seal than the top

Slight movement?????  should be no moivement at all, did your "mechanic" take the chain off and give it a good jiggling about?????

if there is a mm differance then somthing is wrong..

Slight movement is measured with a indicator !

yer at the time  I took engine to a bike mechanic shop ,he wriggled the shaft around and thought it was fine and wouldn’t affect the seal at all, in hind sight I wish I had of got a new shaft bearing fitted , don’t want be stripping it down again .

I’ve got some led indicators, are they ok for measuring it haha

Pluck one of your hairs, thats about the right dimension.

Until you work with tight dimensions most dont understand.

Fitting a new bearing is not quite as easy as a new seal!!!!!!!  you have to split the crankcases

And then worry about the cases being proper to accept a new shell. If you check that kind of thing that is.

the output shaft on my old GSXR1100 years ago was very wobbly !!!!  when i stripped the cases the needle roller bearing (at the other end of the shaft) had collapsed and all chewed up, that give the shaft shit loads of play and caused the ball roller behind the sprocket to split the outer race in two !!!!!!  also fecked the shaft

Don't make any sense that, shipmate??????? 

The output shaft  bearing isn't a shell, if that is what you mean.. its a large roller, and what do you mean by cases being "proper"???
