Baldini

Front UJ exploded at 30k miles. UJs/shaft had been misaligned from new. Maybe frequent replacement is Guzzi's answer to poor manufacture or mismatch of components at assembly. Good idea to check shaft is correctly aligned. KB

Your as old as you feel & I feel about 8. Except for the aches. & pains. It appears you subscribe to the "this one broke, I'll fix it one day when I have a bit more time, meanwhile I better get a working one to keep me on the road" school of motorcycle ownership - a man after my own heart.

Oh no not him again...

Factory marks can be incorrect, don't trust them. Best check alignment of shaft for yourself. The original shaft assembly in my Scura could not be aligned correctly & was either badly made or a mismatch of parts.

I'm told you can align clutch plate by LOOSELY assembling clutch on the motor, attaching gearbox (requires a bit of jiggling to get input hub into splines in plate) then removing gearbox & tightening down clutch fully. I didn't have any luck with this method so made this, which worked fine. As I recall, I measured across gearbox bellhousing face to make tool, then attached it to motor across crankcase bellhousing face & used an old clutch hub to centre plate in clutch.

It's the rear bearing on the upper lay shaft. #23 in this drawing. Part# 92 20 12 25 (ball bearing 25x52x15)

Emulsified? Can't remember exactly what it looks like when fresh. this from a vintage 12 years old bottle...

The failed bearing appears to be the rear bearing on the upper lay/secondary shaft. Here's 2 more:

It may not be re-assurance but I've come to think RM clutch assembly components differ from Scura. It may just be a question of production numbers but can anyone here recall hearing of an RM flywheel failing in a similar way to those in Scuras? For my own peace of mind, I'd be really interested to know why your output shaft bearing failed, & to that end it would be useful to know how driveshaft was aligned. You may have missed my earlier post re my exploding Scura (the driveshaft was badly misaligned, & the paint marks totally wrong from new). Thanks for any info on the driveshaft. Cheers, KB Here's pic from earlier post:

THIS. When you reassembled the driveshaft, how did you align it? Did you use factory marks? IME these can be totally incorrect. Check alignment of two UJ's looking along the assembly. My Scura exploded front UJ. Below pic on L is aligned as it came from new (aligned according to paintmarks) & prior to damage not previously disassembled. KB PS: Audiomick - the missing triangle looks to me like something unrelated placed in front of the clutch assy.

0 - 140mph in 4.5 secs good grief Docc, what have you done to the poor thing? Hope you keeping well. KB

Baldrick knows Guzzis inside out. Not sure if he's still in the business, last I heard he was in London area. Website looks a bit out of date: baldricksworkshop | Moto Guzzi service , repairs , diagnosis system , MOT , Fuel Injection , gearbox,bevel box,

Thanks for the info. Sounds like a really well sorted bike. Lucky Colt - hope you enjoy it! Thanks, Pete. Good to see you're still alive & kicking. They still ask in the pub about the big baldy fella who dropped in for a beer one evening. I plead ignorance Scura exploded UJ some years ago, I got the bits to fix it but never got round to it. Tonti went in the shed to delink the brakes, but never came out. Hence my absence from this place. One day. All the best, mate. KB

What work has been done on that Scura? (hope all's good w you Pete).

This . Also I dropped the triple clamps down the forks a little.

Is there any damage to the casing at all? Any cracks? Unclear in pic.

Cymru is Wales, in Welsh. Dunno about exotic, but it's a great country. Took up mountain biking about 8years ago & despite the years, never been so fit! Try the hip flexor stretches!

Cycling has helped my fitness no end. Muscles tighten up esp if I've been riding MTB then sat driving for a couple hours. Hip Flexor stretches have helped me a lot.

As Pete says, that looks like a (two part) Scura ring gear assembly. Only difference that I can see is, on mine the gbox-facing side of the ring gear itself is relieved around it's circumference. I'm guessing it may be the RAM version, but I can't check cos it's in the trans.

Best Wishes, Paul. Good luck with this.

2002 Scura 28k miles - wrinkle paint is fine - no bubbling. guess I'm the lucky one.

Docc, Have you checked UJ alignment? I had v similar failure. Don't trust the factory paint marks, that supposedly show alignment. Mine were wrong, & in fact shaft collar/UJ's were welded so as to be impossible to align correctly. Roper was always banging on about stresses set up by wrongly aligned UJs. KB

Alternative clutches: RAM - Single plate kit w alloy flywheel. Transkontinental - no longer available I think. Lightened stock flywheel & ring gear (u using a starter motor?) What power does your engine make? Is clutch OK? I have had no experience with v powerful motors/stock clutch, but I'm surprised you can't get it to work. You probably know the following people? if not just Google search - all are experienced w fast Guzzis & could help: mtiberio ran Transkontinental: see http://www.guzzitech.com/forums/threads/transkontinental-clutch.6393 Pete Roper, Martin Harvey (Australia), Todd Egan (Guzzitech), mike Rich (USA). Amadeo Castellani (Raceco UK - now works w cars - but massive knowledge), Jim Blomley (think u can get him at Quill exhausts) (UK). Peter Hindley raced a 1100 Sport on IOM a few years back: http://www.guzzipower.com/TT/HindleyTT.html Full of admiration for your project! I've done a fair few IOM laps on my old Tonti, but never raced there. The mountain is a real test for breather system: mine failed big time one year, delighting my Fireblade mate who figured I'd finally killed the old thing when I disappeared in a cloud of smoke... just cleaned it up & carried on... Good luck. KB
