The very impressive novelty looks like a bicycle handlebar fitted onto a starter motor which is then belted to the pony motor!!!  Better than a pull rope.

Anyhow, I called Warren Cat in Abilene, TX and spoke to a salesman, and Cat had stopped production of the D7 Diesel-Electric tractor, and will bring it back at some point, and the D1 is the size equivalent of the D3, and I did not ask where the D2 and the 'new' resized D3 fit into the lineup.

The new D7 is a high drive and the D6 has an electric drive version called D6XE.

The Equipment Journal magazine says:

“Current and future nomenclature
  • D3K becomes the D1.
  • D4K becomes the D2.
  • D5K becomes the D3.
  • D6K becomes the D4.
  • D6N becomes the D5.
  • D6T becomes the D6.
  • D7E becomes the D7.
  • D8T becomes the D8.”
Looks like a good solution to the confusion of 3 D6 models.

I'm the bloody pensioner that I was thinking of first!  Much less likely to fall off what passes for heights around here

Looking at it on the small screen I had not ciphered it out.  I had thought that the handlebars were hydraulic hoses....

I'd been looking for an affordable dozer/  crawler for sometime . I had hoped to find an IH but this came up for sale about 70 miles from home. Hadn't run for 2 years but we got it running and moving and hashed out a deal on it. Track chains are bad but sprockets and idlers are decent. I've put about 40 hrs on it since I bought it last summer. I've learned a few things since then ! Including how to remount tracks ! How to get a crawler loader out of a bog! Now I get to learn how to fix what I presume is a bad steering clutch!

my dozers come under the dead weight category, though they have all been used in the last 40years.

Cat 977 that I bought and spent a bunch of money on to get the steering clutches redone. I loaded a lot of gravel before one side stopped driving.

Cat D6 that I bought and got a fence row cleaned up with, before one side stopped driving.

IH TD 14A that was a town machine in a gravel pit on a farm I bought. Town put it out to bid, but winning bidder waited until the engine was set up before he came for it. I got ahold of it for junk price after the buyer found out he couldn't just drive it on his trailer.2034992831_2021-03-1317_13_37.thumb.jpg.85edb38725aa6e5c933ab7ae6a44e75b.jpg

Probably the most valuable of all of them- a 1937 Caterpillar Fifteen that i traded a junky C20 pickup for in 1980. Homemade blade added to tractor. Cat hasn't run in years.

...that  , Bill, is an impressive  array of  American Steel....You have been hanging out on us for all these years  !!!

The old 9U  and the next model (B)...are a real pain to do the steering clutches.....On the "B" pictured on this topic....I did the clutches..independantly.....outside, so I could move the tractor forward, incrementaly, to access  those studs via the ''hole''  thoughtfully provided  by the manufacturer's.........Of course this meant a 4gallon tin up on the canopy....to gravity feed the brute.....and  being very 'supple''   in the body positions  , whilst crouched over the 'command centre' to shift it forward every time....yes a pain allright !!!

Don't want to go to Caterpillar here, but you only need a jack under the sprocket on a grouser. Much safer than operating it without the deck. I have gone to the most dangerous jack of all time the Hi Lift or Handyman. But in this case I don't have to bend the old bones to pump the hydraulic down so low. Your not lifting tractor just pushing to make the final turn to line the bolts up to to very small whole. Ok maybe the blade needs to come off, but I have done it chained up to the hardnose. But that got a bit exiting when we had a 4.? something earthquake and the blade started bouncing up and down. 

 

Since I started: bill do you know what broke on the 977? I had a 9u D6 ( the same rear end as the 977)do the same very suddenly I thought. One little hiccup that I thought it was slipping, while pulling a disc. A hour later pulling up a good hill, pull the working side and I stopped. I knew something major had to of broken. When it came out the only thing wrong was very, very, very weak clutch springs and very thin plates. I was very amazed how fast it all quit pulling.

the 977 has been down for 4-5 years. I was only using it to load gravel in my pit, not on any long hauls. I only remember that it will drive on one side and not the other. The same thing happened to the D6- one side goes and the other doesn't. After all the money I spent on the 977 to get it operable, I haven't been motivated to go after the last problem on either one. I wouldn't be a bit surprised but what it is the same broken pieces on both of them.

Mike, as long as there is a chance (no matter how small) of getting the old girl resurrected, I will keep all the parts intact. Thanks.

At one time Caterpillar had a much tougher product than anybody else. Not to be kicking other brands but in the road building business they lasted longer with average Joe operating them. At lot of owner operators knowing the weak points got along fine with other brands. The IH gas start diesels need to be cooled with 5 to 30 minutes of idling on the end of a hot day or you run a good risk of cracking heads. That was something the payed help had a hard time doing, so the reputation of IH engines went in the toilet. So used Cats sold for more. So salesmen looking for suckers painted anything yellow.  Both IH and AC picked up on this and there construction equipment lines got yellow paint starting in the late 50's to 60's.  Once all the new ones where yellow many people painted the old ones yellow too if they repainted.

I still have this TD9-H. Had several other TD-9's and a 14A and my favorite was a TD15-C, sold it as I didn't need one that size.

Ray...re the "jack under the grouser''   bit......when I pulled the clutch 's out of my old "B".....tried that "normal ' method, but gave up because it was winter here.....and the ten ton bottle jack and timber block would dissapear   into the soft turf......hence kept the old girl running.....

Problem that you possibly would not encounter  in your  more arid climate....??
