I'm working on a 76 340 Jag thats been sitting a long time. First off, I got it to run but it had no compression on the PTO side. It also clicked like hell from the bottom end. I pulled off the PTO cylinder and the rings were stuck in the piston.

I also noticed the clicking is coming from the aluminum collar (Labyrinth Seal) that goes between the 2 center crank bearings. I can look down a small 1/4" oil hole and see the collar sliding side to side. I'd assume this isn't normal because it makes a terrible noise. Now the question is, whats the fix for it? Will equal compression from both cylinders stop it from slapping side to side?

Any help is appreciated.

Thanks.

Yes mine is a Suzuki but it is the same set up as the Kawasaki's. Mine is also RPM related, speeds up with RPM. If I roll my engine over to a certain spot and then grab the clutch and keep rotating the clutch back and forth it'll just keep clicking away.

I guess I just don't understand how it could get loose in the case all of a sudden. Its not a wear item on that surface.

I don't think mine has an o-ring around the outside of it though. Thats the problem.

You could try packing it with grease? Maybe use a needle fitting on a grease gun to get down in there and use a grease that won't break down quick, like maybe a synthetic? This is just a bandaid suggestion, the real cure would be a tear down and rebuild. The grease might get you a season or two of riding.

Well the engine is all back together and "tick free"! I put on some new crank seals and new rings with a fresh hone and it runs like a champ! It'll sit there and idle all day and not skip a beat.

That center seal fit pretty loose into the case but everything else about it looked fine. All I did was get a 3/16" diameter by 1/2" long hardened dowel pin and drilled the top half of the case a 1/4" deep and the center seal a 1/4" deep and put the pin in. Problem solved!
