This was probably one of my most favorite build days. I definitely enjoy mechanical and electrical aspects of the build more than riveting skins...

I put the bearings in, clearance checked the crankshaft, camshaft and governor thrust washer and all within new limits. I found it easier to drive the thru-bolts in through the left side, slide the 0-rings on, and then slide the right side of the case onto the left while laying on the workbench (as described in the manual), and then put a couple side case bolts in and moved it to the engine stand, which is MUCH easier to install bolts and to torquing; the stand was in the hangar since overhauling my Baron IO-520 continental a few years ago - definitely worth having.

One upgrade I made on the bottom end was buying Lycoming's diamond coated flat lifters, which are supposed to be a good answer to spalling and little higher horsepower compared to roller lifters, according to the good folks at Ly-Con.

I am waiting on a few more parts to continue with the top end, but it was a good day to get the bottom together and happy to have it all together and rotate smoothly.
