WD-9 / 4-71 Detroit conversion


IH OAK

Recommended Posts

I saw on here in an old post where someone mentioned that there was a company that made conversion kits to put a 4-71 Detroit in a WD-9. Does anyone have information on these kits? Who made them? Were the rear ends able to handle that much power?

This going along the lines of your TD9 engine issues?

No...I do have a great running 4-71 in a wore out P&H excavator sitting here...No I aint putting it in my dozer.

Just wanted to learn, I couldn't find any info on it except for that thread and it is archived.(Now I can't even find it)

I think this is the topic.

I guess it wasn't a commercially available kit. I couldn't remember.

Any info on this guy's (@IHterry's) build?

The 4-71 would be all over the d282.  3-71s would take on a 282.  They could be had over a 100 hp.

Hmmm, I assume no one makes a drop in Detroit adapter for a 706 do they? You know, for if something happens

Those Detroit engines were the catalyst of the invention of hearing protection ...

Absolutely miserable. At one time we had four 671 (terex C6, gallion T600, Gardner Denver compressor, and an IH truck) and one 471 (Michigan 175 loader) engines . Glad a few are gone . Don't use any of them anymore besides the Gardner Denver 750 compressor

I spent a whole summer in a Hough 65 with a Detroit, I think it was a 371, I have 0 fondness for them.

Only one I have is a Silver 8V92 435 hp in a 1975 cabover Pete.  I like it.

I forgot we have a generator with a silver 92 on it. Pretty quiet compared to the 71 series engines .

"Palouse" who used to frequent RedPower posted pictures of a TD-14 that had been converted to a 471 Detroit.  Palouse was from the Palouse region of the sate of Washington.

I am with Big Bud-----thinking a 371 would be more inline with a WD-9.

I ran a couple of 371's as irrigation power units back in the 70--80s.  They were rated @ 70+/- hp @ 17--1800 rpm. 

The rated rpms on the 71 series will be in the 1800+/_ range (300+ rpm more than the original TD-9 or 14.

53 series Detroits speed range was approx 1,000 rpm higher.

A wide selection of injector sizes offered a range of power output with all Detroits.  They did operate best near their full rpm rating------not an engine to idle back much.

They were very adaptable to transplant------or build around.  Damm shame I have gotten too old to get anything accomplished anymore.  I have access to two 371s and two 453s (all in various needs of overhaul)-------and always wanted to transplant a 471 into my 1943 model TD-14.  We could do some swapping and long distance hauling and both be in business!!!!

I built a hydrostatic drive ditcher tractor using a 453------very simple engines to work with.  Very dependable------the 453s were rated @ 112 hp.

 

All of those days are behind me now-------but I still love the "music" of the old two stroke Detroits.  :wub:

Good luck------keep us posted.

Used to own a Pettibone Carylift Super 15 with a 471 DD but it was originally a 453 DD. It's still running.  Screamin demons, for sure.  😱😈

The old 2 stroke Detroits have the same problem the 282 has, most of the good service techs have retired that kept them running the last 40 years.

   If I had a 282 in a decent 706 I can't think of a better engine to replace the 282 with than a 5.9L Cummins.

   I really liked the 318 Detroits, 8V-71's,  They REALLY screamed in trucks in the 1960's, when I was 10 years old and they passed the RD450-6 in the CO-190 I was riding shotgun in.  First Detroit I was actually around much was a 4-53 in the Austin-Western grader scarifying roads, it spent lots of time with all six tires scratching for traction.  The brand new Austin Western grader the next summer had a 4-71 and a muffler about the size of it's fuel tank.

    When I drove over the road I normally had a choice of something Cummins powered, but I did get stuck in 6V-92 powered trucks a couple times, after I got out of town and on the road, a day off seemed like a much better idea.

My uncle had a 1900 Oliver with the Screamin’ Demon in it. Their farm was about 3 miles away from us and you knew when he would start plowing in the fall. Sure miss those days, uncle is 75 and retired, and I think that tractor is gone. 
The only Detroit that I have driven, was in an old truck crane. Not sure what size it was, I only drove it twice. The only thing anybody would tell me was “Drive it like you stole it”

I had a 1957 Oliver Super 99 GM. 371 Detroit in it and it finally ate 1 bull pinion which I welded new teeth on and reshaped them. ---It did work for many years after that and we ended up having to sell it. The last I heard he was still using it.

As far as Detroit motors, ----- BEST motors out there!! --- LOVE UM!!
