So you can see the markings on the bearing.

Ok, thank you. I keep re-reading Fred Eaton's assembly instructions, but can't find anything about the fit of the lay shaft into the bearing inner race. I'm assuming it should be a slip fit, but mine won't go in, even after freezing the shaft. I should reduce the shaft dia. with emery paper, correct? (Sorry if this is considered thread hijacking)

With the layshaft polished clean with 0000 steel wool, mine was a hard push fit (not pressed).

Sure makes dismantling the gearbox easier!

Tail light assembled and installed. It's like a weird jigsaw puzzle, nothing straightforward with the MkIII.

Oil filter installed and piped in.

Oil tank painted, installed & piped in.

It looks like there are no heat insulators between the head and intake manifolds? Is that intentional or maybe just an artifact of the photo?

It looks more like a paper gasket rather than the heat insulator?

There just sitting there for a photo op. Filter still needs spacer rings, too.

I have the insulators and the washers. Just filling time till the clutch locating circlip arrives.

Didn't anyone notice the chain adjusters aren't on? My God, someone could get killed!

Circlip arrived, so I set the primary drive in place and gently snugged in the clutch basket.

Checking primary chain alignment - I used vice grips to gently clamp a section of alloy angle to one of the alternator housing studs with one face flat against top and bottom edges of the primary case near the drive sprocket, then measured the gap to the face of a primary chain plate.

Image

Next, I relocated the angle back to one of the chain adjuster studs and measured the same gap near the clutch basket. They were the same, using the shims that were previously installed. So, no worries.

Image

Primary drive and clutch center nipped in place.

Transmission cover installed with new seal & gasket, kicker installed just after this photo was taken.

Image

This is as clean as this area between the engine and transmission will probably ever be once it leaves the shop.

Image

Primary cover with new seal & o-rings for the inspection caps, new gasket of course. Z-plate just set in place for now...
