The differcultly was ring gear & clutch plate were in the wrong way around. Looking a picture's on phone didn't show ridge on plate and indent on ring gear. Printed photos out and bingo the problem was obvious. Gearbox now fits onto clutch- easy. Now in process of putting bike back together.

Good thinking on both ideas. I will give them a go

OK I'm going to remove gearbox & clutch and start again. Probably next weekend

Its only got a single clutch plate so that plate only needs to be centered. A twin plate would need 2 plates lined up & centered. I took note of all line up marks on clutch & flywheel before I pulled apart plus reference to Greg Benders video so that part should be good . I will try with trans in gear. I suppose I'm trying to hit 2 moving target's at the same time. How do you know when it aligns?

Not a different g/b Vince repaired original one. G/b proving stubborn to refitt. I'm obviously not getting splines lined up. I can get cases 2mm apart. I can move alternator nut. If I tighten nuts to join cases just a couple of turn's then I can't move alternator nut. If I ensure gap in between cases is the same all round then g/b should be lined up with clutch splines. I should then wiggle alternator nut untill splines join. In theory.

I'm reinstalling original flywheel & clutch. Plan is add a V85TT to fleet to do any long distance riding on so mileage on V11 will be less. I've used a vinier caliper to centre clutch plate. Have another go at gearbox tomorrow

Thank's Doc. Makes total sense when you think about it. Out come's gearbox again

I'm having trouble refitting the gearbox. I can't get the gap between the gearbox & engine cases to close up. Is it that the splines on the gearbox are not meeting up with those on the clutch plate? The manual talks of a clutch alignment tool. Do I need this?

I use a DRC stand. The 15mm pin fits my RM fine DRC B2510 Road Front Stemup Stand – Cycletreads It's the opposite here in New Zealand 30+ C.

Yup. When I removed it to drain oil it had metal fragments attached to it. Not a nice sight

Pick up completed gearbox yesterday. Great service from Vince. 2 weeks earlier than I expected and cheaper Got some painting to do before I re fit. Paint flaking off from top & bottom of gearbox plus some touch ups to swingarm etc

Many thanks for posting correct page

Yup my bad wrong page

Working on what needs to be done to install flywheel & clutch Found this on Greg Benders website for an 850T. The clutch is different for the RM but is the instructions correct for the flywheel for the RM? Install the flywheel and clutch - Roy Smith's Moto Guzzi 850 T3 engine rebuild - Project motorcycles - Topics - Gregory Bender (thisoldtractor.com)

I saw one in Germany on Ebay. What happened to yours?

Just heard back from Vince. The failed bearing was rear one on upper lay shaft. Can any one point out in parts diagram which is the bearing that failed?

I'm not sure. I will find out

I've got no paint marks on my driveshaft so when I had refitted it after I had swing arm out last year I aligned it as per diagram in workshop manual. I would post a picture but I'm at work and manual is at home

I've got flywheel away being crack tested (thanks MartyNZ)

Great to hear another RM owner's experiences. May I ask why did you install the new clutch plate?

The $64m question is if flywheel is ok do I replace it anyway

The shattered bearing in gearbox told us problem was defintley there. With gearbox out it made sense to check the clutch and flywheel for any wear
