Engine: Timing marks

[sasquatch]

While reassembling my Champion engine, I noticed these timing marks on the flywheel. They are on the back side of the flywheel, not the clutch side. Once the flywheel is installed, there is no way to see these marks. Why are they there?

So's to be viewed thru an opening on the front side of the mounting plate at the left rear corner of the motor block?
That was the spot to time an early Champion 6. I believe that method show up in my 1941 Shop Manual.

I must have an earlier flywheel in mine then because there is no hole in the mounting plate. (The engine is a 1949 2R.) And I don't remember seeing those marks on a different 1949 2R I worked on a couple of years ago.

Yup! Now at home and am looking at page 84 of my 1941 shop manual.
Nice picture of the hole and the marks. I had forgotten the pointer stands out from the otherwise round hole.
I guess a 6 volt Champion flywheel, is a 6 v Champion flywheel, is a 6 v Champion flywheel?

I’m getting ready to do the timing on my 1941 studebaker champion, on those flywheel markings, on UDC 1-6 the distributor should be pointing at cylinder 1 correct?

Yes, as long as # 1 cylinder is on its compression stroke.

To make the timing a bit easier I always assemble the engine with #1 TDC on compression stroke then set the distributor accordingly, points just opening on #1. The rotor can go in two ways one is obvious 180* out.
