Hi Vic, Thanks. Can you mark up this drawing to show what you did please?Thinking about all that engine breathing thing I decided on a real seal for the mainshaft and binned the old spacer and scroll thingy between both bearings. At same place I put a standard seal plus a hardened spacer for the seal lip. I would never do screws around the bearing seat castings so as not to weaken them.

Yea, fair call. Is ET60/2 the sprocket with the inside of the boss ground for the seal surface?My thought is, as foolish as it may be, the primary oil will be the lubrication of the drive side ball bearing if the engine is to return to stock. And the chain tensioner blade (and triple chain ) are continually supplying shaved steel particles to this very oil.
Seemed best to allow engine oil to lube this large ball bearing. Isolate from primary.
Open up the fit between ET19 and ET77.
I forget what was done with spacer ET19.
I dont see any ET60/2 sprockets. Whats up?
May I suggest that you look very closely at what the lock tab connects to & whether it actually prevents rotation of the nut? I have recollection of an article in MPH which may have indicated that the tab washer is futile. Correct me if I'm wrong.Parts needed for ESA revision to D style. Plus more springs.
The lock tab washer seems to be a nice addition as well.
