I will get some pics. They did use two different sizes on 4 inch only. Yes a lot of them did not use a bearing on the left side rim only the sprocket. I put a bearing in the rim also with a spacer between the srocket bearing and the rim bearing to keep it in place. Other wise the bearing will not stay in the rim. Only a 3/16ths spacer between the sprocket bearing and the axle bracket. That is with the old rims with 3/8ths bolts. The newer rims use 5/16ths bolts.
AHA!!! That may answer another question I've been struggling with.... wheels. I have at least 3 different "lil indian 4" steel wheels", your comment about bolt sizes may clear that up for me.
The ick on the wheel on the right is just black paint wearing off, it's actually a really nice wheel.
Anyway.... the wheel on the left has 3/8" holes, and needs bearings with snap rings. Correct wheel?
The wheel on the right has 5/16" holes, & has bosses extruded into the bearing cavity to act as stops, no snap ring on the bearing. Correct wheel?
I'm guessing both are, for different years?
