Re: 350 crankshaft question

Thanks for your kind words Nigel, I have often wondered if there is any of the legendary "Bill Lacey" coursing through "your" veins ? Yes this particular crank seems too have survived the last sixty years remarkably well, I have another one which "is" 1- 1/2 thou plus, ...

Re: 350 crankshaft question

This is all very interesting, It's my first "Ducati" crank, and I take your point Nigel re the clock location. I did check the oil nose, and there was no indication of ovality, perhaps I struck lucky. Your bearing on the gear section is certainly the answer to a worn nose, but in my defenc...

Re: 350 crankshaft question

Yes Jordan, it's a belt and braces arrangement for sure, as things are under a lot of pressure before the pin makes it's first move, mostly with a jump. I usually true cranks on the bearings if possible, as it eliminates any possible errors with running them on the shaft centres. Brian P1060447.JPG

Re: 350 crankshaft question

As Matt has said a pressed up crank is a pressed up crank, but to be certain not to damage things, a solid jig is important. This is a jig and mandrel's I made to press apart and assemble my 200 crank. I thought it may be of interest. The pictures are just mocked up, the crank was assembled a while ...

Re: 4-speed clutch mystery

To the best of my knowledge, there is no spacer between the rear of centre hub and the basket outer bearing, as your hub measures 33.5 mm overall, and is 1,6 mm below the outer face of the basket, it would seem to indicate a variation with the basket? Both the clutches I have are from 200 SS's , wit...

Re: 4-speed clutch mystery

Hi Ian, measurements of late type clutch as requested. Working from the outer face of the basket, the depth to the inner clutch plate contact face is 25 mm. The depth to the outer bearing face is 31 mm, the distance through both bearings and spacer in the basket is 28 mm. The spacer between the bask...

Absolutely beautiful, but I could not live with those plastic oil pipes and jubilee clips.

Re: Ducati fork assembly.

I've never seen any spring seats in the forks I've stripped. Considering how well the forks were manufactured for the period, it does seem strange the springs set on the screw heads.
I made some nylon seats, as I felt it would be a better arrangement.
