Being an adult sux sometimes...

One step forward...

When the front bearing on the output shaft went out, the shaft flopping around did some pretty significant damage to the ring gear. I have feelers out soliciting opinions on whether or not I can live with the ring gear in that condition. The pinion appears to be okay.

If I have to replace the ring gear, I'm guessing ring and pinion should be replaced as a set and seeing as the pinion is machined into the end of the shaft, that means a ring gear and a shaft and I suspect that'll be seriously expensive.

We shall see, I guess.

Sigh.

Well, since you're soliciting.... :rolleyes: I'd clean it up and use it. Most ring and pinions can be shimmed to adjust contact area. As a guess, I'd say you could shim that so the damage isn't in the contact area.
 
That's what I'm hoping for. If I do that and it defecates in the sleeping apparatus later, I am NOT taking this sucker back apart!

yup I concur with Jim. I’d go over the damaged teeth carefully to ensure that no little bits can come off, clean ‘em up with a file, shim it judiciously - and then I’d go ahead and run it.

after all - you’re looking for a few hours of fun/year - not 10 hours/day of making a living with this old gal.

Well, hell.

A mechanic whom I trust implicitly said "file off the rough spots and put 'er back together!" He said he did that on a GMC Astro road tractor 20 years ago and it's still running.

I'ma still wait for a price as I need bearings and such anyway, but if Larry says it's good to go, I'm a believer.

I agree with him. Back when I was a kid who couldn't even afford to change his mind, I had a Mustang with a whine and leak in the rear end. Pulled the cover and the ring a pinion gears looked worse than yours. Replaced the cover gasket to fix the leak and figured as soon as I could afford it, I'd get a junk yard rear end and swap 'em out. 2 yrs later I sold the Mustang with the same whiny rear end still under it.

yup - I’m still with Jim on this. While it would be nice if those gears were all nice and shiny-smooth....nothing on a bulldozer turns very fast and so I’d clean’em up, load-in the heaviest gear-goo you can find and enjoy.

I’ll bet the only whining you’ll hear will be guys like me voicing their envy at your cool new toy.

I trust most of the opinions about the dirty pinion except that one internet pic is not near enough to make a decision on it. I would hope that pinion is cleaned and inspected under heavy magnification with light at the least for cracks in teeth.
After all, a bull dozer is certainly not too weak to start tearing teeth off. And It won’t happen in the shop. Where would it break on you ? :doh:
