Apparently Bolens DID use a shaft collar, but with a set screw that went through the spindle. I believe some of these shaft collars were lost or replaced with washers and a roll pin, Why? because shaft collars cost a lot of money compared to a roll pin. Unfortunately without the shaft collar you get a lot more play with a roll pin and washers, causing the bearing to disintegrate in a short time, thereby causing stress on the spindle in the axle and wearing the inside of the axle. And that is what I believed happened to to my tractors front end. Just the inattention to details like using the shaft collar. Manuals don't show pictures of actual parts, they are generic drawings, and representation, in the Bolens manuals we see the shaft collar and set screw, but it really doesn't show us or tell us the size of the set screw, or does it? hmmmmmm, I'll have to do some more reading
EDIT: I went back and looked through the manuals it says the cap screw in the shaft collar is a 1/4-20 x 1" that means the set screw went through the shaft collar and into a hole in the spindle. I don't know why these little details bother me, but they do
