Anyone Know What This Machine Screw Does?

That's part of the problem. I don't know what or where any of the passages go to. I've never had an Ascot engine apart yet & don't know the lubricating flow path.

If all goes well, I have another local Ascot enthusiast coming over this week end to have a look at it. I'm hoping that he will know what is going on here.

Thanks

Thack:
I'm guessing the hole above the screw may be for the shift shaft. Here's a diagram. Maybe it will help you.

J6G1Z:
I was looking at that diagram earlier & was thinking that it might be the balancer shaft. The oil passage is the furthest forward in the side case.

The clutch operating link is at the opposite end.

I looked at it again today & the screw blocks the oil passage & seperates it into two different passages. It's definately been done to split the flow for the cooler.

Thanks
J.

Thack:
I think I solved the oiling path for you. See the two pics with labeling. The oil from the pump and oil filter is pushed to a pressurized area which splits into the crankcase and the clutch cover. The pressurized area supplies oil to the shift shaft and transmission via the little oil jumper. In the cover, the pressurized area feeds oil to the crank, upper end and the balance shaft.
The screw in the pic above is right below the crank oil feed galley. I wouldn't restrict oil there or anywhere below the cam oiling feed. Maybe it will be fine.


EditI see now that the oil from the pressurized area goes out to the oil cooler and back into the oil system about the cam & crank oil feed galleys.

Thack:
Crankcase side.
