started today with axial end float/play straightforward task: mount crankshaft in cases, measure end-float. insert spacer acc to calculation. measure end-float. finished.
still there is some voodoo involved. first measurement 0,67mm. inserted 0,65mm spacers. second measurement 0,07mm end float. hmm somewhere found another 0,05mm play. added an extra 0,05mm spacer. third measurement 0,07mm float. hmmmm, cases are made of putty. added more spacers and am satisfied at 0,04mm with the thought of putting the cases together with ducati superbond liquid gasket.
Hi Anne, nice progress, in the pic below you can see the Devimead solution for lubrication of the Timing side bearing, the original pressure feed is blanked and a small cavity is created on the top side of the bearing boss allowing oil to drip into the bearing.

hi Gavin, that is indeed a clever solution, being a needle roller the dripfeed is more than enough. As you can see in my earlier posts I used a scrub srew with a 1mm orifice. Same setup as with the old engine which lasted some 32 years/ 12000 miles. Regards A
been a while but this christmass the new engine is work in progress. solved the axiaal end float voodoo, made a new bearing out of some phosphor bronze. in the end it is just a 5,25 mm thick slab of bronze, milled to the correct dimensions. end float is now 0,04 mm
next jobs on the list are: 1. camshaft 2. the SRM-Oilpump 3. gearbox, pity the five-speed from Scotland isn't available yet so have to resort to the four-speed.
Nice to see your moving forward again. With regards to the 5 speed clusters, I've been surprised by the lack of interest, other than myself the other two which I know are in use, Mark Parker and Gavin Eisler are happy with the performance, of the 11 sets sold others don't really give you much feed back.
Hopefully your post can generate a little more interest, at the moment there are your self and four other who have shown an interest. I need to order a batch of ten, so if anyone is interested PM here or get in touch.
