Homemade sprocket liners for my Allis Chalmers HD9

[dieseldave]

Not too many sources for AC undercarriage anymore, and I wouldn't want to put much $$$ into this old girl even if there were, so I decided to make some sprocket liners out of pipe. I know it's soft metal and won't last as long as a new sprocket or rim, but I don't put a lot of hours on this machine so they'll be ok for me (I hope). The previous owner had put new chains on, but not replaced the sprockets and they were running out of "time" and really tearing the bushings up. HOpefully this will solve it.:drinkup

That's pretty cool Dave. What model Fat Allis do you have? You may have said before, just can't remember.

Edit: LoL, I see it in the title now...HD-9. Cool!

Maybe this will help.

Cliff Notes: It says before you weld your liners in if you heat them up to 1400 to 1500 degrees then quench them in oil helps to harden them. Thought you might find it intresting.

BTW, It's good to see a little Old School still going on in the World.

Thats a great fix, love it:drinkup

That's a neat link- thanks!:drinkup I debated about hardening them first, but then figured I'd see if it was going to work at all first before getting too involved. Plus, I'd rather my admittedly unscientific and experimental "repair" to be softer than the tracks so that it will wear instead of them if I don't get it just right. If it goes well I'll harden them next time around.

Atco, I know I used some pretty long and confusing words in my initial post, so I'll post a pic of the smoky old beast to reduce the strain on you (I'm sorry, but I just couldn't resist... I figure it's maybe an 8 hour drive from Knoxville to here, so if you read this tonight I figure I'll get punched out sometime in the AM- maybe nearer to lunchtime if you stop for breakfast. If you don't get back to the BB until tomorrow morning I'll figure on an attack by supper )

Looks like a good fix. My only concern, would be, will they match up with the track rails, looks like a bunch of work, but worth it, if it matches up with the rails.
Its been several years, but I saw on eBay a sprocket repair kit. I havent seen them in a while. These were premolded units that weld on over the worn teeth.
Keep us posted

It's worth a try. I've got some tall orchardgrass around the edges of the property that would probably offer pretty good cover. There was a suggestion in another thread that perhaps he couldn't swim and that there would be safety in large bodies of water, but he says he can so there goes that idea. Too bad, I had already committed to memory the location of various ponds, streams,and swimming pools and was ready to plunge in should the need arise. I wonder if he's a good climber? There's plenty of tall trees around that might offer an avenue of escape... For now, I'll just wear a striped workshirt so that I blend in with the grass and hope for the best.

Naaa, ain't no need hidin'. All I got to do is grow a beard and wear a go ta meetin' suit and tie and he won't recognise me!

Then, when he ain't lookin' I'll sabatoge that Detroit in his Fat Allis by backing out the buffer screw a couple of turns on the governor and leave him scratchin' his head tryin' to figure out why it keeps stalling. But we ain't gonna tell Dave, OCR, we'll keep that our secret. :lmao

looks like a good job on the sprocket rebuild dieseldave.Thats a nice looking Allis Chalmers HD-9 high lift dozer.I also noticed the carco winch on the rear.Those old carco's are great winches.For Allis-Chalmers or Fiat -Allis parts I go to www.minnpar.com .

I got that winch off an HD11 years ago- it was well worth the effort, it's worth it's weight in gold if you need it. Years ago there was an unfortunate incident where both tracks fell off the D9, and it was in a mudhole where we couldn't jack and block it. Doubled the wire around a single block and the HD9 pulled it right out onto solid ground. The picture shows a later stage of the operation with one track back on the Cat but at first the ole Allis had to pull it out dead sideways. Hardest part was holding her back- I had her tracks and bucket buried, tied off to the backhoe with it's buckets and stabilizers buried, and had that lashed to the Mack and trailer with the maxi's on

Uh oh, I didn't figure on sneakiness and subterfuge. I suppose that I'll just have to respond with extreme prejudice to any well-dressed strangers I see around the place and hope I don't get too many innocents by mistake:guns
This is getting serious- first the man wants to sabotage my grader,now he's after my buffer screw Is nothing safe?

Hey, you told me you was going to be hidin' in the tall grass...you wasn't supposed to see that!


That's pretty cool dave, having an HD-11 winch on an HD-9. It was the other way around for me. I used to operate drill rigs mounted on HD-6, HD-9, and HD-11. Those things were notorious for getting stuck with a drill carriage and drill rods hanging onto the left side. Had to get a dozer to winch me out more than once.

I've been in the grass, but took the laptop with meointhead It's been raining pretty hard here all day, not so sure how much longer I can hold out . Gettin' cold, too.

As far as I could tell, the HD11 was just about identical to my HD9 except it had a 516 Buda instead of the 471. Might have had another track roller, eight per side rather than seven.
Mine gets stuck easy, too- there's a lot of weight on those narrow triple grousers and it's easy to get in trouble on soft footing. Thank goodness for that winch:thumbsup

Man don't get me started on those old Buda engines! I ran a HD-6 that had a 4 cyl Buda. That was one of the best sounding engines I've ever heard when it was twisting a drill rod. I miss the old Buda engine Allis Chamler machines.

The sprocket repair is finished and the old girl is back to work. The inserts seem to work well, no problems so far except for the track falling off when they settled in a bit and let the track loosen up too much and the operator didn't catch it in time. With the track back on and properly adjusted the machine works great and seems to have twice the power it did before the repair. Makes me wonder how many "dog" machines I've run over the years were victims of worn undercarriages?:beatsme

 

[willie59]

Nice repair Dave, really nice! :notworthy

Now, how you gonna fix the operator that let the track fall off. :tong

It could be the added power of patting yourself on the back.

You should be proud of yourself BTW.

Anyone who can fix a problem with their brains and their hands instead of their checkbooks deserves to be looked up to.:notworthy

IMO That fix is also keeping within the spirit of when that machine was made and the men that run it when it was new.:usa

I was so busy congratulating myself that I didn't notice the track coming off until it was on the ground:lmao Seriously, I really appreciate you guy's comments. I get quite a bit of "why are you fooling around with that POS" and it's nice to know that not everyone thinks that way.
