1984 FJ1100 - Leak on lower left-side?

[IronBuddha]

Hi folks,
I've got a pesky oil leak somewhere down near the shifter area. Oil is getting all over my chain (it likes that) and on my back tire (not so good). I tightened a few things, but after a ride I get the leak again. Also, I was pulling out some oily fiberous material. Is there a seal down there somewhere I'm not seeing? I'm used to the Seca 900 and the Seca Turbo...on those there's nothing in that area to leak. Please HELP!!
Thanks,
IB

Sounds like the clutch slave cylinder.

If it's oil (not brake fluid) and it's oiling the chain, then it's the output shaft seal and/or O ring. See #25 and 26 below:

Actually 24 & 25, with the emphasis being 25.

You also have to look at the shift shaft and clutch push rod seals which are both in the same area. The pushrod seal will blow back to the chain and the shift shaft seal could blow up to the chain.

I have all three seals in stock, I have never replaced 25 in the 16+ years of working on an FJ.

Thanks Randy, I misread the parts list, #24 and 25 it is.....If it were those, would he have to split the cases to install them?

You do not have to split the cases to replace the main shaft seal. Pry the old one out and press the new one in... According to Randy, no oil loss either...

Thanks Mark, good to know.

First things first, make sure it's not just the results from enthusiastic chain oiling   If it's definitely oil, and not dirty brake fluid (clutch system fluid, that is), I'd guess the pushrod seal myself.  There's a good bit o` pressure behind that thing, as everyone who has started the bike with the clutch slave off will tell you...

Easy enough to find though.  Odds are it's made a huge mess of that area of the motor.  Get some simple green or other handy degreasifying solution, take the clutch slave and countershaft covers off, clean until you're sick to the teeth of doing so, ride a little bit, and see what's what.  You're sure it's not just a nick in the oil filter housing-to-cases oring?

Guys,
THANK YOU for all the info!! I was talking with my "Harley" buddy today before I read your responses, and he basically told me the same things. Gosh, I didn't know those guys in Milwaukee knew anything about "wet clutches" (LOL).
Seriously, I really appreciated the maintenance tech tips. Now the oil is that "dirty, brake fluid (clutch system fluid, that is)" as andyb stated. I thought it looked/smelled different from regular engine oil. Plus I didn't see my oil level in the window look any lower. I also thought I smelled that "Hypoid gear oil" smelling oil that you use in the shaft.
I think you guys hit the nail on the head when you said its probably #24 or #25. I haven't pulled anything apart yet, but if #24 is the "fiberous" seal, that must be what I was pulling out yesterday.
Randy, I'm going to e-mail you again to try and buy these 3 seals from you. Not sure why mine had to go, and you never had to replace one in 16+ years! I guess I'm just lucky like that (LOL).
Lastly I'm releived that I don't have to split those cases. I wouldn't be looking forward to that. Especially since I'm not a mechanic. I can do a few things, but internal engine work is above my paygrade. Thanks again dudes!!!

Clutch slave cylinder!!!!!!!!!!!!!!!

Didn't you just say it was brake fluid?  Those seals will not stop a brake fluid leak.

What the hell, don't I get any respect?
My first responce hit it on the head.

Oh well, I tried.

Good call Leon,  I was right there with you, ready to respond, until I saw that you had the same idea that I did.

[Pat Conlon]

Kudos...You did good Leon. That was also my first thought but I was diverted when he said oil.......

I did not think about the clutch push rod seal, that's a good one.
