I know I'm gonna catch all kinds of greif for this, but.....

Ok guys.. Need some thoughts (and I don't want to hear how stupid it sounds either).. I have recently inherited a 2-71 Detroit engine. I was first told it was a 3 cylinder.. but it isn't. I was told it ran when it was pulled from a crawler (but who knows how long ago that was) I know it still rolls over, so that's a plus..

I've seen one put into a Farmall M and I thought it was kinda neat.. it was done neatly and looked good.. But I don't have a Farmall M.. I was given a 44 Massey though (no motor, no tin.. perfect home for a engine it would seem) and I have a bunch of "damaged" tin from the 33 I have been working on for years

My plan is to unite the 44 chassis and the Detroit and the beat up tinwork.. Keeps it all from winding up on the scrap heap (I'm trying to preserve a relic), and in the end I'll end up with something different to play with..

Just wondering if anyone has done something similar, and how I would go about getting my clutch/pressure plate/ input shaft to work. I know I would have to build an adapter to go from engine to bellhouse.. and I know a machine shop would most likely be involved, and that's ok too.. It's not something I plan to do overnight as I would like to see it get done properly and hold up

Thanks for any thoughts

You would have to have a flywheel from the Massey maybe redrilled to fit the back of the diesel...so the starter would work. Also, measure from the flange surface of the block back into the pilot bushing hole minus about an eighth of an inch for clearance...the same for the input shaft of the transmission to see how long it comes out from the transmission flange to see how thick you need to make the engine to transmission adapter. If the Massey has an iron frame, (I forget) you'll have to make mounts to bolt it to the frame....Gee...you're almost done. Do you have to have a fuel pump or would the gravity supply it okay? ohfred

Sounds like a great idea, Brad.

My Father was a field engineer for GMC Truck and Coach. I've always had a fondness for Detroits.

I am looking forward to the replies on this one, I have a 3 53 I have kinda the same plan for. Was leaning toward an Oliver 880 to put it in.

A fun project, but how much power ?
What"s a 2-71, 142 cubic inch, or a 3-53,
159 cubic inch rated at ?
I always wanted to put a 3-53 in a John Deere
model 435. It should almost bolt in replacing
the stock 2-53, and you"d just have to extend
the hood and maybe the steering.

Talk to your Detroit dealer. There are a number of different bell housings and flywheels for the 71 series. All 71 series share a lot of common parts, especially the in-line engines. Also, you need to see if the direction of rotation of the 2-71 is correct. They come in LH and RH configerations. I know that, since they are two stroke, they can be relatively easily reversed, but I never got that far into one. They are relatively easy to work on. Get you a 71 series parts, service and repair manual. Used parts used to be relatively easy to find, but but since they have been discontinued, they will probably be a little harder, depending on the area. Truck salvage yards are a good source. Also, get you a good supply of hi-temp sealer, as they are well known for leaking oil. The serial number will determine the approximate date of manufacture, and will determine if it is a lo-block (flat head gasket) or hi-block, which uses o-rings instead. The hi-blocks are the later N-series, which develop more power, but if get hot, it'll cook the o-rings almost every time. The 71 series was developed in the late 1930s, and were disc ontinued about 10 years ago because of environmental restrictions. They were good engines in their day.

Hello Brad Gyde,
I got manuals for the DD engines and some specs as well. Let me know if you need some info to get started. E_MAIL is open or you can post here.

Guys, Thanks for the input so far.

As I said, it's out of a crawler.. I called who I got it from, and he said it's out of a HD3? Allis crawler.

I will look into the rotation of the unit and compare to the stock 44.. I really don't want to get into reversing the rotation of the engine.. sounds like a pain to me..

I should have added that the engine has the bellhouse and such from the crawler (over center clutch) and the only reason I'd like to use the tractor bellhouse is to maintain foot clutch as opposed to hand clutch. It has a splined yolk and a short shaft for the crawler.. remove the original driveshaft from the tractor, cut it at the "coupler" have a yolk put on that end (at the coupler), and have the short shaft from the crawler shortened/lengthened as needed. This would probably be the easiest way, as then I can move the engine forward/ back to sit in the right place for the radiator to stay in the original location, and the motor can be higher/lower than the trans. input shaft (Within reason of course, I know I can't have a large difference, but a half inch or so should be ok I'd think, as I'd have a u-joint on each end of the driveshaft).. Hope that don't confuse everyone.. if it does, I'll try to take some pictures and re-explain..

I won't be really starting this for a few weeks.. maybe more.. I got one tractor that I'm going to be painting, then I'll have to wait til crops are planted, as I'm not the best fabricator, so a friend is going to help me with that (I can think it up and make it work, my skill level is just not so good.. ) and I'll try to post some pictures as we go along.

Guido, I'll likely be in contact from time to time.. Having some literature could help out on this endeavor.

As for horsepower.. I haven't confirmed anything, but the 44 should be around 45 drawbar, and I was told the Detroit is about 50.. So not really gaining anything really.

Sorry for writing a novel....
Brad

You can get some serious ponies from a 2-71 if you know what you are doing... For comparison figure a 238 was a 6-71 natural... that's 40 hp / hole...

You are going to have to make an adapter plate to mate the DD engine / integral bellhousing to the massey bellhousing... Then you are going to have to worry about the flywheel, etc. Out of a crawler I would assume it is a variable speed governor...

This is our 49 M with an original 2-71 retrofit from DD. Installed by Peninsular Diesel in Detroit in the 50's.... Should have the sheet metal replaced and new paint on it by later this summer...

If it wasnt used in a boat or a Corvair its a clockwise motor whichturns the same way as every other vehicle ever built in the USA.Its a pain in the you know what to reverse.Head ha to be turned round,Cameshaft and counterbalance shaft swapped around as well as the timing gears in back,blower has to be put on other side etc,etc. Yours turns right.Put it in. Hoss

Neighbour back home had a M-H 55 powered by a 3-53....Its been 30 years since I saw that tractor and I don't remember much about it other than it pulled a 4x16 trail plow ,a 40 plate disk,ran on 23.1x26 Rice and Cane tires and was rather LOUD!

I will say that the 2-71 was out of an Allis Chalmers model H D 5 crawler. I owned one 30 some yrs. ago. Had a loader on it . really not over powered , but OK in it s day. Yrs. latter , one of our M-M " G " farm tractors had a 3-71 in it . Was a real good rig .

Rootsy,

Is that the former Roger Bezek tractor? (It was bought by Van Gasper when Roger had his sale a few years back) I have a feeling I know you in a roundabout way.. You're not too far from me.. A couple guys from work told me I should track you down, as I wanted to look at this tractor to see how it was done, to give me some ideas

Brad

I believe so. We were at that auction and my father was the back-up bidder on this tractor at that auction. The winner called him a couple of years later when they had become bored of it and offered it to him. It is now at home in Ida... Later this year (once I finish this God forsaken JD B) it'll be at my place so that I can finish going through it.

I'll let my father know you are interested in checking it out. He's been going through Chemo for the past few months and has been sort of down and out. If he is up to a visit I'll email you his phone number.

He also has a photocopy of the instructions that came with this "kit" from DD.
