Abit more Coke.
It was actually made until 1974. with 25271 units being made.
Initially it consisted of the A model 44 inch gauge. B with 60 inch gauge both with 4 roller track frames, later the E came with 60 inch gauge and 5 rollers and the G model the tracked loader version.
The AC badged Buda engine powered all crawlers until 1960 when AC newly developed direct injection 6000 series engines took over at s/n 13322.
The next major change happened at s/n 14474 in 1961 when the 6E became a more deluxe model with oil master clutch standard and oil immersed steering clutchs and brakes; both being hyhraulically power controlled.
A powershift model the EP was also added at this time.
About this time the A was dropped so the 4 main models were E EP G and B.
The B was also available with 5 roller frame and oil master clutch and both E and B models had the option of a 4F 2R speed gearbox, this was the standard G box.
The EP had 2F 2R.
All models continued until 1974 with various minor improvements. With approximatly the last 270 models wearing the Fiat Allis badge after there takover of AC on 1 1 1974

Hey Coke and Merv: Very nice detailed info on the great 6. Wondering if any of the components of the HD6 lived on into the FA line after the 270 Fat Allis badged machines? Wish AC was still alive and building the Crawler/Loader lines! Merv and Coke where did you get your source of info. I would like to include it in my AC library. Thanks much - Orangeman

Google search , found several sites and just picked some off one . Then that info did not say the rear housing of the HD6 was the same as the HD5 nor does it give interchange of parts between the two machines or the facts the HD11 steering clutch parts fit into the 5 & 6 machines. Then the site in Utah has a lot of pictures and such on AC machines, the one I listed under pins and bushings for 6 ------------- Faith isn't a jump in the dark. It is a walk in the light.

Hi Orangeman.
When Fiat stepped into the picture it evicted the small AC crawlers and replaced them with there own machines such as the FA 7 8 10 14. Most previous owners with HD6s and 11s either kept rebuilding them or abandonded ship to komatsu. FA sales downunder dropped off to zero and the agent eventually dropped the brand and went to john deere.
Is a exellent book about AC by Norm Swinford thats full of alot of crawler and other info.
Alot of my info came from talking to people who had them and looking at alot of books; and parts and service manuels. Alot of contractors had HD6s in my area when i was younger. Haven,t done much work mechanically inside them, but do know my way around crawlers; have been working on and with them for 35 years; mainly with caterpillars tho; but have always had a soft spot for Allis,s as thought they were a well engineered machine.
Have recently got a HD6EP i intend to keep and tidy up.
Mactractor on here has also done alot of repair work on his collection of 6s and 11s and knows alot of the mods that happened to them. ------------- tits tyres and tracks they all cost you money |

HD5 is where I got involved and in this area as AC dealers in heavy seemed to change often the dealer network lacked expierenced technicians and sales.
When AC/FIAT came in they did away with more dealers dropping the line as the parts supply syatem was consolidated into Chicago area. Minnpar in Mpls did mostly the Industrial line but could get some parts for older AC before Fiat deal.
The demise of the Industrial left a few strong dealers like Herc-U-Lift still able to get and service many machines but the small independant repair shops and used parts became the source for much OEM and aftermarket parts.
Now with the Fiat/Allis changing to New Holland the dealer network has changed again in the construction end. It's hard to find much information at a dealer now and like the one in my area they are usless along with the fact they overcharge 20% markup above book standard retail on all their parts. So crooks in business not only kill any brand but leave a bad taste for others who might own the machines before the new dealer took over.
I have a FD5 also and as far as thet machine it's a good unit and cheaper to run and was a lot less in cost than a D3/ D4 Cat of same size or power. Kind of wish I had bought a FL5 or FL7 machine a few years back to go with the FD5. ------------- Faith isn't a jump in the dark. It is a walk in the light.

| Our HD-6's, a B and an E are for all intents and purposes toys. They are great little tractors and I enjoy operating both of them. Having owned both Caterpillar, John Deere and Allis construction equipment, the up side on the Cat was the parts and dealer support , however the down side was the cost to purchase. John Deere never worked out for us at all. It is very unfortunate that Allis Chalmers did not survive. They had their problems as all machines do, however they had a lot of good ideas which the other manufacturers did not implement until years later than AC. |

Hard to believe that Fiat could take what was at least number 3 in Crawler Dozer Shovel sales in the 70''s and lose so much volume that they could not exist here in the U.S. Wasn't Carol Stream Fiats last ditch attempt to distribute and sell Fiat Allis here in the US? Gosh I wish some venture capitalist could bring back the good ole Allis crawlers, dozers and shovels.

| good looking machine. Does it have a working transmission pressure gauge? I believe the screen you're looking for is in front of the trans, below the cover plate for the governor housing, that is if you have a governor. That screen filters fluid for the steering clutchs and the trans pump, mounted on torque convertor housing. |

MINNPAR in Mpls MN may have some things for the machine . There are several bone-yards that also have parts or can locate for you . Thill Track and Tractor in Eau Clare WI is one source for parts. ------------- Faith isn't a jump in the dark. It is a walk in the light. Faith is not guessing; it is knowing something.

Hi Jonny
If its overfull id say its got water in it. Drop the oil out of it. About 70 litres.
Pull the suction screen for the transmission and steering pumps. Located at LH front of trans; below LH brake pedal. Read back in doctorcoreys posts about his HD7G, hes just been down this road.
Clean or replace the screen; change oil if need be and flush if necessary.
That is a 1973 machine, the last of the EPs and will have no ground speed governor or push pump, and will have the later transmission pump.
Rippers are a allis TR6, early ones have 2 rams later ones have one.
Winch you want is a Carco E30PS. But these are as rare as rocking horse poo; welldown here anyway.

You,ll have to go back a few pages, but time is cheap, have a good read and check all the simple things first before you buy a new pump.
Check the suction screen and hose. Hose may have perished and is sucking air etc.
My 6EP was sitting dead in a paddock too with no drive. Turned out it was full of water, and water had turned oil to cream; pump couldn,t suck it up.
Dropped all oil, flushed it, cleaned screens, filled new oil, changed filters; and away it went, drove it down hill onto truck and home.
Mine is a very early one but Mactractor on here has a late one like yours 88Y24937 and his has alot of improvements and used to go quite well; so yours is the last of them too. ------------- tits tyres and tracks they all cost you money |

Takes about 70 litres. ATF or a 10W transmission oil can be used.
Is also a suction screen for front section of pump, located on RH side of transmission.
This is just a scavenge pump to return trans oil to rear housing. ------------- tits tyres and tracks they all cost you money |

Getting back to the subject of HD-6's, there was a tractor sold at auction last week on Purple Wave. The serial number was HD6ST-20xxxx. Is anyone familiar with this model designator? It was a turbo charged HD6B. ------------- Curt Anderson HD3, HD5B, HD6AG,HD6B dozer, I-400,615, 616,620,720,ACP25 lift truck, 1956 D Grader, AC 540 loader, AC #84 plow, Simplicity tractors, Agco MT225, Agco 2025, |

The letters ST dont sound right, but the turbo the AG had was optional on E, and EP. Never saw any stock ones down these parts, but some turbo and manifold assemblies were plundered from 7G's to go on 6's. |

It was stamped on the data plate of the tractor. It is pictured on the Purple Wave Allis Chalmers sold items. I assumed it was an arrangement similar to Caterpillar which the serial number indicated SP at the end meaning special equipment. ------------- Curt Anderson HD3, HD5B, HD6AG,HD6B dozer, I-400,615, 616,620,720,ACP25 lift truck, 1956 D Grader, AC 540 loader, AC #84 plow, Simplicity tractors, Agco MT225, Agco 2025, |

Hi Guys, My son and I took on a new restore project in the form of an AC HD6B. #14991 and motor #6-15256. We have loved digging in learning together. We have a Pump repair facility where we rebuild vacuum pumps and industrial pumps of all kinds and shapes, so we have lots of machine shop and welding capabilities. We began by draining everything, lots of water, mucky oil etc. Pulled the starter as it would not engage, and found the bendix gear chewed up. Replaced the gear and decided to check the flywheel with a bar for engine mobility. Ceased. Pulled the injectors and loaded the cylinders with a good penetrating solution, 50/50 acetone ATF, and let her sit for a few days. We rocked her slowly for a few days and she finally gave way. Put the starter back in yesterday and gave here a 24v shot in the fanny and she puked out all the penetrating concoction we shoved down her throat. We were excited. We decided to clean the injectors really well before going back in with them. Here is where my first question comes in. We got a good spray pattern out of 3 of the injectors. However, one just wouldn't chooch. Looking closely at it under a jewelers loop, we saw lots of pitting and decided to replact the injector tip or whole injector if we could not find just the tip. We are coming up short all the way around. Does anyone know where or if these old Bosch injectors are available? Tip# DLLD 150S153 or full Injector #KBLB9681/13. We are new to the forum and new to Allis Crawlers. We love restoring things as a Father Son team. Looking forward to all replies, and we will post pictures if anyone is interested. Pretty sure this is a wet clutch, as it has a screw on filter by my Left foot and a second dip stick by the oil level. Thanks in Advance.....

| Thanks gemdozer for your reply. I have googled American Bosch Injector and read lots of American Bosch info, just not finding anything to match my exact injector. I had a typo in my orig. message. The injector nozzle I am looking for is a DLLB 150S153. IF you have this injector, please PM me and let me know how much you would will take to one. |
