Tonti stuck clutch

[HRC_V4]

I had not planned to go into it due to mileage, but probably something I do need to do on my Quota, sounds like a good winter project.

Weekend project if you're slow.. although I've never done a Quota..

I think we’re talking about the Cali 2 here Chuck in which case it’s yer basic Tonti ‘Crab’ project. The airbox is a trifle more involved than the earlier ones but really the ‘Nuts and Bolts’ are essentially the same.

Many years ago when I was racing with Rob we used to be able to swap a clutch between practice and the race! The bike was a lot more stripped down though than a road bike.

The crabbing has begun....

What needs to be removed from the front, wheel, fender, anything else?

I really need more room.....

[docc]

I didn't think anything had to come off the front when crabbing . . .

Doc,  I'm concerned about the clearance, if the engine stays still, and the frame pivots at the lower front edge of the engine, the front suspension is going lower and get closer to the jack.  I'm would have to the the bike raised quite a bit if the front wheel is still on.

Dunno. I haven't crabbed a Tonti.

Although, I would be using some suspension straps/ chain fall for extra security.

Why would the frame pivot around the front of the engine? In the image above if all the engine mount bolts are removed  as you lift the back of the frame the assembly pivots around the front axle even with the wheel on.

You will have to lift it high. See this thread on Wildguzzi.com for some samples, and method to restrain the bike on the stand.

In the image below (from the link pressureangle provided) you can see the pivot point for the frame is the front engine mount, and you can see the fender is getting pretty close to the jack/engine and the rear of the frame doesn't look like it is high enough to pull the the transmission. This is probably a better picture of crabbing.

From Pete Roper's instructions on this Old Tractor;

Off with the footrests and the frame bolts, but NOT

the long bolt going through the timing chest, that on

some bikes is also attaching the side stand at the

front of the engine. (Fig.1). The frame is later in the

process being tilted up using this bolt as a ’hinge’,

i.e. the bolt/nut should be loosened, not pulled out!

That is my next step, lucky the Harbor Freight lift has holes just in front of and behind the cylinders on each side of the engine, so I am going to run a strap around each cylinder to pull the engine down to secure it to the stand.

All-y'all need to expedite @HRC_V4's progress here. The XXI South'n Spine Raid is just four weeks out . . .

I have to expedite my own self too... waiting for transmission seals and lock washers. Then discovery of what else is missing.
Guess I'll go order tires now

My pup at the time, Austin, did a clutch job on his G5. I saw the hanger door go up and 4pm, and he rode it out at 10 pm. 

You need "the box." that's about the only special tool.

In the example you have kindly shown us Chuck if this is the way you do a Tonti clutch then the term "crabbing the frame" isn't appropriate and is what has me confused. This is "pivoting the frame" and not the same thing as "crabbing the frame" as previously mentioned.

Here is how I handle a V11 engine out. Jack the bike up with the basic under engine lifter. (Note the simple wooden support that fits the sump and lifter and means the bike can be lifted with 100% stability with the lifter alone) Then support on the stands shown then simply let the engine assy out the bottom. Simple and safe. Should be able to do the same on a Tonti with a little sliding the engine backwards surely.
