Tired of rear sprocket wobble
I deceided to do this mod on my rear sprocket attachment. The C-clip ring was showing wear along with the gruve it sits in therefore allowing the rear sprocket to have alot of excess play. Instead of shiming the clip I decieded to drill completly thru to the back of the hub. I installed 4-5/16 grade 5 bolts, 3 inches in length thru the hub assembly. I left the rubber stud inserts in place. I shimmed the back of the sprocket with two flat washer for each bolt to insure it would sit flush on the hub. I then bolted the sprocket on with the nuts and lock washers facing out. I reinstalled the orgional C-clip sprocket holder ring. I then mixed up 4 packages Of 4 minute JB-weld and poured it into the bolt heads in the back of the hub below the bottom edge for the brake shoe. This would restrengthen any weakness caused by drilling that removed material for the center hub support.Kinda like pinning the heads on a race car. With the new wheel bearings and this mod Im good to go. I will keep an eye on things but Im sure this mod is an upgrade to what it was.
