Coast to Coast
Hi guys. I'm doing a GSXR swap and using an '82 Comstar 19" wheel.
On this wheel there is a bearing retainer ring on one side (R), and (i assume) the speedometer gear assembly acts as a retainer on the other side (L).
Upon closer inspection, i realized that the bearing seating surface on the L side is incredibly shallow! There is barely 1mm of "lip" there for the bearing to seat into. As you can see, the other side has quite a bit more.
My Qs:
1. Is this shallow bearing seat position going to cause problems? Of course, there will be spacers on both sides, as well as a spacer inside the hub, but these will only keep everything tight at the inner bearing ring. I'm concerned about adequate support for the OUTER bearing ring.
2. As the new bearings are 9mm wide (compared to stock 13mm) the bearing retainer ring won't be touching the bearing anyways. Do i still need the ring? I can machine a washer to fill up the 4mm difference, but not sure if this is necessary. (see next q)
3. Why do the rear wheel bearings not have this? They sit in the cups and are only supported by the axle and spacers, which all act on the INNER ring.
Thank You!
P.S. This was discussed in this thread, on the exact same question, but after page 8 it sort of fizzled out and i don't have a concrete answer yet. I mean, it works fine on rear wheel applications, to just hold everything in place with the axle and spacers on the inner ring, so want to make sure i can still be OK with this on the front end.
It begs the question of why the bearing retainer was even used on the OEM application? Does the speedo side not have a spacer so needs to rely on the right side to keep everyhing in place?
