Part identification help
#7
Chris, the engine is a 1 1/8 " crank 1929 unit.
The flywheel and crank were tightened up properly when this observation was noted. Zetomagneto identified  the location of this washer which was not used on the engines with the larger cranks.

The washer mentioned is listed in the parts book for  1929 ( I managed to find it ) as "Flywheel distance piece BB14"

Without this washer there is a gap of about 1/8" between the flywheel and the bearing inner race, so I made the assumption that this washer was supposed to be fitted there and under compression which it isn't at the moment.  This leads me to think that the washer has compressed over the years, but not sure how. The crank and flywheel are both stamped with the same serial number so  they are the original matched pair.

My current thought is that the washer is supposed to compress when the flywheel is fully home and tightened on its taper such that the bearing is loaded without the washer preventing the flywheel from seating properly on the taper.
