    Posted: 02 Apr 2026 at 4:37am
Got a salvage yard crawler with a bad engine. No injection system now and engine turns stiff. Anyone tried to put another engine into a HD3?  
What would be a good transplant engine to set in it if able to do so?
 Or does someone have an old Allis-Chalmers diesel 175 cube engine laying around that was taken out of HD3/ D15D that would be usable for donor parts?
 Here is a pic of crawler, blowing critter nests out of valve train area cuzz valve cover was sitting on the two studs.

 On market place, seen a Simpson SJ436E engine says 46 kw, and a Perkins 404...Also a 4 cylinder Mercedes OM616 2.4L Would that make the crawler run like a Cadillac?  
  I might have to go hunt down a D15 160 cube engine and put in, probably be the easiest avenue to go.
   Sure would like to keep it diesel.
        Thanks, JC

I don't know how far you would go to hunt for an engine? A guy in Canada (in BC) swapped out a 175 diesel in his forklift and put in a Detroit 2-53. I know he was trying to get rid of the 175 but don't know the outcome. This is the guy:


He has a thread on the forum here, but the 'search function' is not doing anything for me.

H4 AC used a 2200 AC engine that was also used in cotton pickers and few other units , it was a gas or diesel engine basic and turbo or natural aspirated in different applications 
The Allis-Chalmers 2200 (often referenced as D2200) is a 4-cylinder turbocharged diesel engine utilized in various Allis-Chalmers agricultural and industrial applications, including tractors like the 6060, 6070, and 6080. These engines are known for their reliability but may require overhaul kits for maintenance

That's a nice looking D2200 engine there in your link Coke, just wish it was closer instead of next to the Washington state border.

As far as I have been able to determine, the 2200 series engine (G-2200 gas/D-2200 diesel) was never turbo-charged. I had it in my head that there might have been a D-2400 that was turbocharged, but can't seem to come up with anything by googling.  I thought I read that a D-2400 existed from a head gasket installation instructions sheet many years ago. The newer 1978 433-T and 433-TI engines were the first to be turbocharged and turbo/intercooled. They also were equipped with a Lanchester style engine balancer in the bottom of the engine so they could operate at 2500 RPM. These changes allowed the flywheel HP to reach the 100 flywheel HP mark where the D-2200 only ever got to 50-52 flywheel HP @ about 2000 RPM.

How much HP can a little HD3 handle?  
 The Buda D175 was  32 pto HP.  Couldn't seem to find BHP on it
I sure wouldn't want to go beyond that D2200's range 50- hp

Looking in a 1956  'The Tractor Field Book',  under multi cylinder commercial engines section, They listed Buda having 11 different gasoline power units and same number of diesel units  from the 4B-153 gas / 4-BD-153 diesel to the 6MO-970 gas / 8-DAS-1125 diesel.
 Nothing for Allis there, but Allis-Chalmers  were listed under Tractor Engine Power Units specifications and only gas models.  They were powering their construction equipment with Detroit Diesels prior acquisition of Buda.
Here's a scanned image of the Buda specs from 1956.

When I was down in Effingham was talking to a mechanic there , he said he had a couple D2200 engines and learned that engine handled a TURBO well as AC used it in their cotton pickers with a turbo - got it up to 85 HP rating in that use , said he worked over pump and few other things and had even more HP out of it . 
 So AC did use it TURBOED in product line

Well, I do know that in that same 1978 ish time frame, when the K2/F2 combines got the 433-series turbo engines, the cotton harvesters did too. So, yes they would have been turbo'd from that time on. But, what about 1965 up until 1978  ?? He may have been referring to those engines as D-2200 from his old experiences but they may have been 433 engines.

Wouldn’t a gasser out a D-14 or even a CA be a direct bolt in? No experience with the diesel. The gas we have seems to have plenty of power for what it is, which is Not a D4 haha.
Secondly, we’ve got Deere 440s as well. The gas ones held up fine. All the ones we’ve had with Detroit diesels had enough power to wreck themselves and crack castings. Wonder if over powering an H3 would have the same results.
Glad you saved it, I was second in line if that’s the one that was in the woods.

Having a diesel replacement would be convenient and fun, perhaps, but the 175 diesel is quite gutless for doing real bulldozer work.  I had a 175 in a backhoe and it was underpowered to say the least. In your case it may become more of a toy and then the diesel is fine. A 149 or a 160 gasser would make a better workhorse...
First gear would be your default gear for any 'real work' Cry

Eric, From what I have heard, the gassers were okay, but the diesels were short on power.
 Looked at the numbers and they should have been pretty close in power, but if the H3 got the 160 engine put in, it would have been 12-14 hp difference. make a huge difference. LOL
A-C brochure Literature says
 H-3 has 32.36 hp pto,
 HD-3 32.53...   
1961 Nebraska test - 
H3 NT # 793 - 149CID 32.11HP          11.26 hp hours per gal
HD-3 NT #794 175CID  32.53             12.68 hp hours per gal.
 D15 NT # 795 149 CID gas 40 pto hp  11.86 hp hours per gallon
 D15 NT # 797 LPG 149 CID 30.83 pto hp  7.81 hp hours per gal.
 D15 Diesel 796175 CID  36.51 pto hp   12.72 hp hours per gal.
Nebraska Tests 1963
 D15 Series II 46.18 pto hp,
 LP gas 43.55 hp .
Funny how there was about 1 1/2 hp hour per gal between the gas and diesel. 

Did some searching last night in the H/HD3 parts book, it said the Muckland Tractor came with track assembly 235843 with 18" shoes as standard equip,
 236975 axle assembly pivot (f/54" tread Muckland Tractor)
 235841 beam front (f/54" tread Muckland Tractor)
 235839 sprocket (54" tread) (Muckland Tractor)
and 4512325 pump assy fuel injection (Muckland Tractor) (2000R.P.M.)
all the other HD3 tractors were governed at 1650 rpm 
 Interesting. Thought they were all 48" center to center of tracks. Guess not when you have a muckland. 

 It appears that unlike the difference between gas and diesel as in the D17 tractors having two different lengths of engine clutch shafts, the D15/H3/HD3 had the same length for both, and no difference in clutch assemblies either using a 9 inch disk. The flywheels were different between the gas and diesel. D15 engines do not have a fuel pump on the engine, but the H3 engines did. I guess a fellow could put on an electric pump if he needed to.

  Still like the idea of that D2200 engine above with the hydraulic pump driven by the engine thus having live hydraulic even when you step the clutch in.  But... with the shuttle shift, how often is the foot clutch used?  Might be simplest to figure out the engine in it and fix it or find a D15 or G160 power unit engine and drop it in. 

 Wade, it probably is, I was after this one to go see it since Oct of 2024. And probably even before. It was talked about back in 2020, if I recall correctly. Heard it was hauled away and found it sitting in a scrap pile.
