Stuck clutch - expert help needed

[SIR REAL ED]

LOL 
You'll fit right in!

Now you know what crabbing is. Right? No questions there.

Loop - short for Loop frame. The first Guzzis with the transverse V engine - 1967-74. Their frames are like old Triumphs and BMWs that loop around the engine.

Tonti - the engineer who designed the next generation frame in use from 71 till sometime after 2000.

Before  WG the only crabbing I'ever done was in Alaska  during my misspent youth. The first clutch on a Guzzi was on my Ambo and as Charlie pointed out, swinging the motor to pluck out the gearbox does seem to make more sense.  For years on Tontis  I undid the frame off of the powertrain  on the lower rails with the centerstand deployed and then pulled the transmission while the engine was supported on blocks. As that was always done on the floor, it was stable if not  more time consuming. In any case, if everything is steady on your crabbing rig  you are   golden .The pic I posted was during a 4 hour evening clutch swap due to the dreaded Surflex clutch plates causing clutch creep. The next morning the SP  was commuting to work. The Tonti  Californias are a bit more cumbersome ,at least to me . On the ground it would take me  a couple evenings after work to do the entire job, whereas at work with a motorcycle lift and overhead winch it was about a 5 hour job. and Chuck FYI, I only use 2x6's when crabbing...

The statement "...for creating his signature 'Tonti frame' for Moto Guzzi's 1967 V7 Sport..." isn't correct. The V7 Sport didn't come out till 1971. I think 1967 was the first V7 Loop. Tonti wanted to set it up for racing, but it scraped the frame in corners. He made modifications to the charging system and designed a whole new frame. I think he also designed the small blocks that came out in the 80s.

Correctomundo. It's very similar to the big block frame.

And the reason the tail light is so cool, completing the amazingly good design of the Le Mans.  https://en.wikipedia.org/wiki/De_Tomaso

Except it was the '70s - first small-blocks were on sale in '77.

I’ve thought about it and think a mineral spirits wash could do it, especially if you let it sit for a couple hours.  It won’t hurt anything so it may be worth a try. You will have to tear it apart but maybe you want to delay that until you get organized to do it.

   Thanks for the splainations....Wha t kind of frame does my 2007 Nevada have?  To me, it looks black, and probably made of some kind of steel!

I recall a industrial maintenance seminar where the lecturer was discussing various ways to do things.  One guy kept interrupting with his own special secrets for doing those tasks.  Most of the time, snickers were heard when he outlined his expertise.  After several interruptions, someone in the class said "Man!  You make everything you do more difficult than it needs to be!  I bet you and your wife make love standing up in a hammock!"

He might have ended up as head of MG's R&D division.....

Up until the V85TT, all small-blocks (which includes the Nevada) were all (small) Tonti frames.

Alas I don't have to learn to do the CRAB just yet, woke up to a free clutch this morning! A little voodoo can go a long way.

I strapped the clutch lever to bar, plugged the weep hole under bell, removed starter, put it in 5th, removed the plugs, and filled her up with this magic stuff evapo-rust. The fluid doesn't come up to center of the fly/clutch assy, so i left it for one hour, topped up (some will drip out, and the drip rate will slow down as rust gets lifted by this fluid and fills the gaps), then rotate engine 3 bolts (of the ring gear). Then another hour, top up, turn 1/3 and so on. To let the fluid get in and out of the ring gear holes etc. Every so often I went down to the garage and gave her a nice spin sort of like a washing machine. Top off, come back in 2 hours. Top off. Go to sleep, wake up, clutch is free.

Then I gave it a bath with hot soapy water and heat gun is drying it out now on low heat.

Excellent!!

Kinda sorta. The big blocks don't have the swingarm pivot in the transmission case.

Lino Tonti designed the small-block frame, so it's considered a "Tonti-frame".

Evapo-Rust is pretty amazing stuff!

Thank you!

I'm adding this one and Milkstone to my list of chemical helpers.

I hired a 70 year old guy who lives in Madison Heights to do some heavy equipment work for me a couple years ago.  We hit it off when I was telling him about all the old stuff my father used to own.  So he said I have some stuff to show you.  By the end of the tour, I saw somewhere between 100 and 150 old cars, trucks, tractors and assorted construction equipment.  Including some real gems like late 40's thru early 50's Ford F600 4x4's.

I told my wife I like to have a few of those vehicles just to see how well they come apart.  Now with a crane and a couple swimming pools full of Deep Creep or Ed's Red........

Smart man!  Always try simple first.

After its really well dry, the test is a hard pull in third gear bumping the redline to see if it slips. if it passes that test, run 'er until failure, with any luck at all, will be thousands of miles!

I did that with the LMV that had an oiled clutch. After the mineral spirits trick, Dorcia was not amused on the back.. but it showed the clutch was ok.

First ride done and she is working beautifully. Clutch is perfect in all gears full throttle all the way up the revs. These Conti Classic Attacks are amazing tires, the balance and turn-in is incredibly good. No oil leaks. She wants canyon roads!

  Glad that lovely lemans is back out on the road where it  belongs.  You are now a candidate for the prestigious red suspender award! 

[John A]

Sometimes waving bones over it works!

[Dave Swanson]

Great work Wicks!  The bike will finally have its day(s) in the sun!

[Chuck in Indiana]

I've been singing Conti praises for some time now.. 

[wicks]

Thanks for that!
