Leaks suck

[WayneOrwig]

And I thought that crabbing a tonti framed bike was a load of work.


Leaking plug above the flyweel.


And I found this rust / damage:

Is that the swingarm bearing? Most of the ones I've seen still seem to suffer from the famous Mandello Grease Phobia!!!!

Where's the leak from? The flange??

Yes, swingarn bearing. Water got in. There was a slight amount of grease, but the seal failed.

The rear drive splines were greased. The front dry and rusty.

The leak is oddly the plug above the flange. Maybe where they bored for the left cam chain tensioner.
I know about the other leak possibilities in there, but everything else is good.

Besides a couple of "marking" left under the beast, any other symptoms that caused you to, er, dig a little deeper?

Wayne, Pete,

Seeing that rust on the transmission input shaft, do you guys think we should be lubing these shafts as part of scheduled service? BMW has been using single plate clutches forever and to lube the input is a required service.

Wayne, If you decide to grease that input shaft, I've been using Amsoil synthetic on BMW. It sticks well, doesn't sling (if you don't put too much on) and should last for the life of the clutch plate. I have been using https://www.amsoil.com/a/Synthetic-Grease product code GLCCR-EA, but the product codes GPTR2CR-EA and GWRCR-EA look interesting.

That rust is the transmission OUTPUT shaft under the rubber boot. I'm going to recommend that people loosen the boot and spray some goo, like chain lube, on the front splines to keep away the rust. There was zero wear at about 35,000 miles, but I don't like to see hardened metal with rust like that.

I have a mixture that I cook up of moly and chain lube to paint on the clutch splines. There is a huge surface area on that single clutch plate, so it is unlikely to get notched. There was no rust on the input splines. But then the oil leak had everything in there a bit wet.

Not sure what to recommend in the swingarm bearing. It is a lot of work, but I think they should be packed with grease early in life.

Oil was running down the sidestand. It was always covered in oil.
I finished up a leaking rear main seal on the EV last month, and I have been riding it to work (better winter protection anyway). I then played around and welded up a motor lift platform for the Stelvio motor before diving in last week.

Hey Wayne...
Kudos on the attack!! Fingers crossed that I can keep from having to do this....

Having that plug leak was an oddity, and I doubt anyone else will see that.
BUT, the rusted swingarm bearing looks like an issue. If anyone gets a chance, I recommend planning to pack that with grease. It is a bit of work, but not horrible.

Would this be something us Griso owners should lose sleep over?

The plug is as Wayne describes. It covers the bottom mount screw for the LH cam chain tensioner blade. I found this out the hard way on 'Mark III's bike when I bust the tensioner doing the cam recall work! :roll: . The plug is identical to the plugs used to cover the sleeve nut on the inner cylinder stud or the gearbox filler plug on post loop frame pushrod bikes (In the case of the stud plug.) or post Mk III five speed gearboxes. It is sealed with an o-ring. Presumably on Wayne's bike the o-ring got nipped or didn't seat properly for some other reason. No, I really don't think it is something your average owner needs to even give a second thought to.

As Pete and I mentioned, I'm sure this is a one off oddity.

I AM now a bit concerned about the rusted CARC bearing. I recommend that anyone with the time, when they get close, pull the swingarm and pack those bearings.

As for the leak in the flywheel housing, go ride. I haven't heard a single other report of that particular leak.

Thanks, Pete and Wayne.

Saw them the first time around and thought you had arranged a Guzzi event on the Barrel's porch behind the rockers. What dealer is that anyway (not from your neck of the woods)?
