Re: Think I found it - Oil leak at push rod

I've got the stainless springs in the clutch too - I barely think I could compress teh spring a millimeter with my bare hands, so I can imagine there's a lot of force at play.

It's such a simple explanation - but I definetly had a "Well duh" moment there. At first the notion that that large seal with all its bolts would fail seemed a bit out there. But after this and thinking about how many thousand times that area has to take the strain of the slave pulling on it, it's kind of a wonder that it held up for 8 years.

yeah a couple 8mm back there probably would have been a good design revision... a few years back oh well.

And I'll be damned, but at the seam between the cover and the case just in front of the center line of the output shaft - I could see something moving. Yep, it was almost as if the pressure from the slave pulling on the cover was pulling it away from the case just a tiny bit.

So it's looking like she needs a re-gooping. Guess I should get my to-do list ready for the shop.

you know, that's amazingly obvious, but i never even considered it. that's why they leak there over time - the intermittant high load applied by the slave. it's a lot of load too - try getting the clutch to release by pushing the rod yourself.

maybe they need an 8mm bolt behind the slave there with it's higher torque loading, not a 6mm.

i love learning new stuff.

Forget the goop, get a gasket from Ca-Cycleworks. Much cleaner install

It definetly showed signs that it had spinning at some point.

Was your old pushrod spinning in its bore before this one?

I had the push rod out. It's not been turning, from the slave side I can spin it in the pressure plate with just my thumb and middle finger pretty easily.

The rod had oil down the whole lenght from the slave side until it widened out again.

Sound like the case seal?

I don't think that leak would cause a low pressure problem.

Guess I gotta clean it all up and see what I can see.

IF it's a leak from the cover to the case - think that would cause a loss in oil pressure? I've been having an issue with the bike not making pressure while at idle when it's hot.

Re: Think I found it - Oil leak at push rod

they leak thru the join between the alt cover and cases above the pushrod tube into the pushrod tube and then out. i have no doubt that it's coming out along the pushrod, but it's probably the alt cover sealant gone bad. at a guess it'd be a 19 times out of 20 thing ime.

if you remove the slave and turn the pushrod you'd know if the pressure plate bearing is seized.
