FH - Assembling the bottom end

 With the crankshaft together and the few internal components of the crankcase assembled, it's time to put them together. First step is to thinly coat the mating faces with Threebond 1215:

With the cases bolted together, we can measure the end float again. This time we have 0.18 mm - last time we had 0.34 mm, and I added one 0.25 mm shim under the bearing. Something has changed, or I have made an error because 0.34 - 0.25 = 0.09, not 0.19...

That's 0.0075" - we are aiming at 0.005". I'll see what shims I have in stock.

The next challenge comes when we check crankshaft rotation - it doesn't. There are two clashes one on the rear of the case, one on the front; the rear is a scrape that allows the crankshaft to move, but the clash at the front is more serious and prevents movement altogether. You can see the witness marks in the picture - this is probably the big end nuts fouling the crankcase:

That's coming apart again.
