Hello all, just want your opinion on this ring gear pattern. You look at something long enough… It’s in an original 55 Chevy truck 3100. Just a rebuild. It’s not racing, but will be a local cruiser. Backlash is good to go and within spec.
I would shim a bit to move the contact surface closer to the root, and away from the outer edge of the ring gear. Pic #2 seems to show a firmer contact mark toward the outside, and not centered on each tooth.
It'll run great. You can chase "perfection" but likely end up right back where you are now. Well done.
As long as you loaded the gear before rotating, the pattern looks pretty good, what does the other side of the teeth look like? I bolt a piece of teflon to the housing which drags on the ring gear, it a takes plenty of effort to turn it over, nothing like actual driving force, but enough to get a good pattern. Moving the contact pattern towards the root as suggested insures under a load the contact point will be centered on the teeth. Starting out centered, the contact will be slightly high under a load, probably no big deal unless pulling a load or racing around town.
I agree. I have replaced the bearings on several axles without worrying about all that. Some rear axles were noisy at first but got quiet after a few hundred miles and seem to be ok forever after.
