Does anyone have a good way to find out dimensions of an o-ring based on its part number? I'm replacing ring and pinion and all the bushings where the the axle pivots on a 4630, Carraro Axle. Parts book lists a Carraro part that subs to New Holland 83930343. But this o-ring I picked up is too big for the groove in the new bushing. So back to dealer do do some double checking, making sure i have the right part. Any other advice for setting up these gears? Thanks!
