pete roper Posted January 1, 2023 Posted January 1, 2023 With the driveshaft? It is aligned correctly isn't it? While a misaligned driveshaft itself won't cause the wheel to lock the forces imposed by the trunnions not being correctly aligned is certainly enough to bust stuff up. 1

While a misaligned driveshaft itself won't cause the wheel to lock the forces imposed by the trunnions not being correctly aligned is certainly enough to bust stuff up. I had driveshaft apart 6 months ago when I greased front grease nipple. I thought I put it back correctly. Will never know for certain now.
cash1000 Posted January 1, 2023 Author Posted January 1, 2023 Swing arm out Front universal joint out Unfortunatley it looks and rotates fine Next step secure bike so it won't fall over (It's on stand that it was on during Christchurch earthquakes so I'm just being careful) Then tomorrow remove gearbox

cash1000 Posted January 1, 2023 Author Posted January 1, 2023 I'm about to start removing the gearbox. Anything special I need to watch out for? 1
audiomick Posted January 1, 2023 Posted January 1, 2023 Don't drop it on your foot. I hope you find the problem quickly, and that it is not too dramatic. 2 1
audiomick Posted January 1, 2023 Posted January 1, 2023 On a more serious note: I don't know for sure that this works with the "big block" Guzzis, but it is in the workshop manual for my "small block" V35 Imola. The constuction is similar enough that I reckon it should work. Undo all the bolts to the gearbox, and then pull the clutch in. On mine, the gearbox then pops off a bit, and you can pull it off without too much bother. Hope that helps. If it is still reluctant, hold a block of wood against the housing and persuade it a bit with a hammer against the wood block. Work your way around, and it should come off. 3

On the "small block" models, as with the old Tonti frame "big blocks", you need to remove the upper frame to get the gearbox out. That means that the clutch cable is no longer connected. To activate the clutch to pop the gearbox off, you need to push in the lever on the back of the gearbox that the clutch cable is connected to. I haven't had a look at the way the clutch works on the V11, but going by the parts lists, it looks like there is a rod through the gearbox that activates the clutch. In your situation, I'd be inclined to try and leave the clutch system connected until the gearbox is separated, so as to be able to use the clutch lever to push it off. You'll have to have a look at the business yourself to see if that is possible. 1

cash1000 Posted January 2, 2023 Author Posted January 2, 2023 Thanks Doc for that. Didn't realise you needed to tilt motor. Nearly there. Got black frame tubing behind g/b to remove. Only problem so far is 2 of 3 screws holding grimca clutch m/c have seized. Will detach tubing instead 1
pete roper Posted January 2, 2023 Posted January 2, 2023 Once you have this thing on the floor or bench. Make sure it's the box by turning both the input and output shafts, in all gears. 1 1

Will detach tubing instead My drawing is probably a bit misleading as it was an attempt to portray classic "crabbing" of the frame. Last time my gearbox came out, the motor was supported, front end strapped tightly into the wheel chock, and light straps to support the upper frame from the pannier racks. I did not even have to remove the frame side plates . . . 3 1
