HD-6G Questions

 If I can help am still have some used HD6 G parts

Hector thanks for the parts post appreciate that, if I buy the machine I may drive up to visit .

Hello Coke: When you reference the early machines do you mean just the first year of production?  

Was or is there a good bearing solution for the timken bearing issue and assuming the commonality between the 5 and 6 machines, were the idler bearings upsized for a shovel machinesdue to the additional weight in the bucket as compared to say a machine that is equipped with a dozer blade?

 

Thanks for the info noted above.  Appreciate it... orangeman! 

Same on HD5 and HD6 on both loaders and blade machines to my knowledge.

Hey Dadsdozer: Yep the son of the original owner let water get in the block over the  past 2 years and number 4 cylinder filled up, engine seized.  He's a good mechanic, but time and elements bested him this time.  

Hello Coke: I could see where the backing up with a full load would be an issue.  Now for the engine.  Since the loader is on the machine it is very difficult to tell if the engine is sound, (i.e. no cracks).   If the block is sound I could refurbish the Buda, but I have access to several mercedes benz 123 diesel good running engines that could serve as a power plant and they would be much less cost than a rehab on the Buda. 

as a side bar, if you do not want the agravation of rebuilding or working on it to get it going, buy it and part it out. if the undercarriage is that good it will bring a good buck as they are no longer available. i have tried several sources just for the pins and bushings and have come up empty handed. once you have gotten the best parts from it, scrap is up and can put a good downpayment on a running machine. i also beleive as coke said that an allis hd5 or 6 will outlast a 955 in  the long run and have less repair and maintenance costs. now a 955 is a larger machine and with size comes expense. certinally your call. does your front idler have spokes or solid? i have a few spoked idlers in fair shape i could sell. where are you located? coke is right about the bell housing matchup, as the detroit should bolt right up. personally, i think a 3-71 would fit nicely and be a relatively easy install. 2-71 would be a little underpowered but that is what they put into the hd5 loaders. i beleive the only big difference between the 5 and 6 was the engine. i aqhve a hd5 loader but do n ot have it up and running so i cannot say if it has enough power. coke had a 2-71 looking for a good home. there are several cheap on e-bay now and are easy and inexpensive to rebuild.

6 has 2 more links in track and 1 more roller on frame. Mainframe is longer and front metal changed to adapt to longer engine also 12V to 24V electrical system

I have an early HD6G, First year, in the 3000 serial numbers. I can see that they made updates to the belt system in later models. My fan/idler mount was worn, had to fabricate special parts to straighten it out. My engine runs good but burns a lot of oil.

I ben in parts business and never sold  a bevel gear pinion shaft for HD6.

Thats interesting that you have never sold a pinion gear. The guy I had visited had about 3 of them go on three different dozers. Last time I had visited him he had welded on a swept back rear onto the newer type straight hood version just for the better rear with good pinion. He cut the rear off of the swept back version at the frame and welded it onto the new dozer.  Another HD6G had a half a tooth broken off of its pinion but he was still using it.

I have a mid 50's HD6G track loader with the tractomotive factory installed backhoe attachment.

Originally came from the Lima Ohio area. The hoe works real well and I paid for part of it's purchase cost by digging the footings for my shed. It's a 2 stick unit (with 2 outside sticks for the stabilizers). I just this past year had to install new steering clutches after a mouse ate the rubber boot on the brake rod and set up housekeeping in the right clutch well. Mouse pee is stronger than JB Weld. Put in the new ceramic disks from General gear and Machine in Boise (a real good source for parts I found). Kind of a long with the hoe, really heavy, clumsy machine but useful and neat none the less. Starts on about the second crank over. Also have one with a ripper (3 gang but missing the teeth) and one with a winch. These machines are surprisingly strong and were every bit as robust as the same vintage Cat. I'm not sure what the Cat equivalent would be but I also have a D4 Cat but I think my HD6G is a heavier, bigger machine. Maybe someone on here knows what the supposed Cat equivalent was.

Those clutch plates can be found used also as they are the same as HD11 parts. Juyst less of them in clutch pack. I changed my HD5 over long time back . I do have a bunch of the fiber clutches (used) and couple metal discs.
