Just some work pics

I asked about welding it, gear shop said no- due to the heat treating process. I may have found a used gear set from a rockwell, I was wondering how far off the dimensions were, and maybe machining something available to fit my carrier? Would I still be into issues with heat treatment?

I do know a good machine shop, I'll look into that on monday- thanks.

Good luck on your parts hunt. The 110 had a bad carrier bearing and grove says it's 20 days out. Ended up having a weld shop fix the bracket. Apparently metric drivetrain parts are hard to get your hands one.

It sure can be frustrating.

Gear set so far unobtainium. Will have to build a adaptor to mount a oil seal because it is not available either, I think I can get a adaptor made to fit a standard oil seal. I think we're going to have to live with the chip in the ring gear. Speedy sleeve on the pinion to yoke adaptor to take care of the damage on it where the oil seal rides.

Both good machine shops by me won't weld it, and didn't recommend it. I'm afraid if I stainless weld it, and it breaks off, it will take out a bunch more teeth, with that piece walking around. I thought about brazing, the piece: if/when it breaks off wouldn't do as much damage. It would ruin the heat treatment of that tooth.

If you want post up the seal numbers and hopefully dimensions, I have access to some of the asian suppliers... no promises of course.

I think it is a isuzu heavy axle. I'm coming up with a possible part # of 1-41210-274-0 for the ring and pinion set and a seal # of 1-09625-030-0. I've got a part breakdown in my terex book that gave me factory part #' and they seem to corespond to the isuzu system.

There is no number at all on the seal, nothing. I'll get the dimensions tomorrow.

My wife got some info from a Hamilton engine sales company in portland out in your neck of the woods. My nearest isuzu guy is not interested in helping. The lady from hamilton thought the seal would be 30-90 days min. maybe more. No luck with availability on the gear set.

This is the pdf I got from hamilton. The oil seal is #100, the gear set (#60) in this drawing has a different # than mine in my part book (last 4 digits only), I'm thinking that's because of a different ratio, maybe a whole different size differential. My breakdown drawing in my P&H book is a mirror image of this one and I have the same part # for the oil seal as this one has.

 

[crane operator]

This is the drawing and the part #'s from my P&H (terex) book, and their part #'s. So far they haven't given me any info on availability.

Hamilton has always been gold for me over the years, haven't done much with them lately though. The seal should be 80x143x10x17, looks like an NOK AH7443-E0 two piece seal. Looking to see what's out there now.

The number you have carries the notation 7X45 which is maybe pinion and ring tooth count? looks like your ring is in fact 45 teeth? The note on the right on the drawing from Hamilton suggests 6X37 a slightly different ratio. 21 spline on the pinion shaft?

 

[crane operator]

7x45 is my pinion and tooth count. I will get a seal dimension this morning. The drawing from hamilton is for a different ratio, and my ratio and part # did not come up in their system as a available part. The pinion seal in it currently is not a two piece seal, but the pinion to yoke adaptor is not factory, they have adapted it to a wing style yoke to get standard u-joints, I had to do the same to the front driveshaft. Thanks.

Oy.... mods on mods, lovely, lol

I'd have that ring magnafluxed while it's out, just to sleep better at night.

That and spend some time with a die grinder to blend in the chipped out area to try to eliminate any stress risers.

 

[crane operator]

Seal is 3.38" ID, 5.62" OD, 1.12" tall (steel), 1.14" tall at the rubber, 24 spline on pinion.

I guess I see no reason to magnaflux the ring- there isn't a replacement available, I would just put in a new one if I could find one.

I do plan to die grind the tooth a little, to smooth things out.

Pics of seal that I'm probably just building a adaptor for. And the new style pinion input, that's been adapted for wing style u-joints, instead of the factory 4 bolt flat flange.

Thanks guys, its amazing that this stuff is so much fun, and they pay us too.

I do get to run crane occasionally too- when I can keep them running.

Manbasket work on some light poles we installed a year ago- there's some defect in them and 5-6 of them are not working already. Sounds like more work in the future.

And another statue. Bronze indian. They used epoxy to the concrete and bolts sticking out the bottom of the statue. If he needs moved again, we're moving concrete and all.

I'm just all cranky because I'm still hunting a ring gear, may have one spotted in Latvia. No- I'm not kidding.

I have found shipping very reasonable from England and Germany for small parts but I don't know how it would be from the Eastern Bloc, for something heavier.

Or two used complete Eaton , Rockwell , Meritor rears.......

Or just a single drive because it seems the rear rear is the only one with trouble. However a quick search seemed to indicate the heavier American ones are not available in the 6.43 ratio.

But I am imagining these things are 65k and 10' wide which would make the used selection pretty limited, maybe Crane Op can clarify.

I've found a used whole old truck crane for about $7,500, its rears may be too light, and I have no idea on condition of the axles., Don't know the ratio, (probably low) but its from 1977, so they would need a whole rebuild. They aren't direct drive like mine- they are planetaries, which is most of what you see used. At least with the whole crane I would get rims (my rims are also unique), and a set of steer axles, which are also japanese (suspension isn't). And the axles are from 1977, even if they are rockwell, they may not have parts available.

I'm getting my truck parts man to price new, which may scare me to death. But if I have to buy the old crane for 7,500, spend another 5,000 getting it home, another 5-7,000 revamping and installing, 25,000 for new axles isn't that far away.

Yes, it is 10' wide probably 60,000 lb housings. I have searched the big salvage yards for used, but none around. I could live without the exact ratio I have now, but I would like to be close.

I don't think single drive will work either- its how I got home, but one little dip and a wheel in gravel and you've got 97,000lbs stuck, or spinning, and that's a good way to destroy axle shafts that are also unavailable.

 

[Birken Vogt]

I meant you could find a single drive of the same ratio and just replace the one that is broken because as a rear rear, it is the same as a single drive right?

Another crazy idea I had is to remove the interaxle differential from the front rear if that is even possible and somehow weld it so that it only drives on the front unless you throw the lock in so it is not loading that chipped tooth except once in a great while. This idea probably won't work for one reason or another. And require you to butcher the good axle.

I did not like the idea of just throwing it back together, die grinder or not. That chip is just so big and wide and right in the middle that I fear the pinion gear will be taking a big dive into it every time it comes around.
