There once was a guy who put a jeep engine in a D4 Traxcavator. I think that didn't work out but he later put a V8 Diesel out of a Ford in it and it worked out well. He took a lot of flack on here for modifying an old Cat in that way. I am sure a lot of Cat collectors would not approve of what you want to do to a 60. Myself I think it would be OK as long as you didn't hack up the 60 too bad. Maybe someday you will get an original engine for it. You have plenty of length with a 60. I think the idea of putting the automatic transmission in is good. Then you will have a direct start, powershift antique Cat. Weight forward is good.

I don't know about a 60, but i saw that combination in an article about a D6-9U conversion.
It was 2-3 years ago, and was featured in "Farmshow" magazine. As i recall, I believe it used a Cadillac, or Oldsmobile V8, with the same donor's automatic transmission.
I believe the fellow had rigged up a driveshaft directly to the input shaft of the Cat's original transmission. It didn't have great pictures in the article, and i've lost the issue since. Maybe someine else has it, or you could try to find more info over at www.farmshow.com.
There was a fellow either here or over at the ACME site that had a 2-ton with a flathead ford in place of the OE engine. I don't recall if he ever got it running or not.

Whoops, had a quick look over at farmshow myself. It was a Ford pickup engine.
The General Motors combination must have been another conversion that stuck in my mind.

Marcoten, Here is a 8R D-8 from down under that has a cat v-8 D17000 engine in it . A real nice conversion but he hadn't finished up the hood and dash or paint yet. maybe he will send in some pictures when all prettied up.

On the Antartic it was rumored there was a 2uD8 with a 17000 V8 in it. I haven't had anyone verify that rumor but at the Museum at Port Hueneme SeaBee Base there is a "crude" model of the rumored 2uD8 with the 17000 in it. May have been a conversion done in New Zealand or Australia.

A local contractor re-powered all his Cat J621 scraper fleet with 855 Cummins, in the 1980's, because he had such a poor run from the original Cat engines.
At last count, I think it was 19 scrapers that had been re-powered.
As of today, all those scrapers have been traded in, and he runs an almost all-Cat fleet. He currently has 83 scrapers in the fleet .. but I think he gave up on the idea of Cummins re-powers, due to the later Cat 3400 engines providing satisfactory service ..

It seems to me that a big dealer or other Co. did have a repowering setup that did use the D17000 engines in the D8s years ago.Maybe OM has something on it.

I have been told that Peterson Engineering, a long-time Cat distributor in California, did the D17000 re-powers on the 2U D8's to give them more 'ooomph' for pushing scrapers.
Then there was another outfit that put the motors out of the Cat DW21's into the 2U and 13A D8's and I just can't think of the name at the moment. It'll probably occur to me about 2 minutes after I post this.
Then there is Don Mearnes from Ipswich, Queensland, Australia, who has dropped both Cummins and Cat engines into Cat D11's to boost their 'grunt'. I understand that he has a Cummins conversion with 1,100 hp and a Cat re-power with 1,300 hp. However, Mr Mearnes is a little secretive about his antics and I'm open to correction on this.
The D17000-powered 8R D8 mentioned above is still in the same condition. It has been fired up a couple of times since its first outing back in February, 2006 but is no further advanced toward completion. It lives about 5 crow-type miles from me and I work for the owner's family company.
If you want a Cat 60 that has a top speed of around 20 miles per hour, I think a V8 car engine and auto trans with lock-up would be a good way to go. The old 4-banger Cat 60 gas engines did about 700-800 rpm on a downhill run with a stiff tail wind. Most car V8's that I have had anything to do with run up in the 5-6,000 rpm range. Should make for some 'interesting' track wear figures, at the very least. Unless you govern it back a fair way.
Just my 0.02.

HE Lowdermilk Co’s, Inc. re-powered all there HD19 with Cummins engines years ago. No pictures.
Yes Deas I believe it was Peterson that did the repowering of the D8s.I have rebuilt many of them old engines as here in my area with the coal strippings years ago there were lots of drag lines with the D17000s in them. Also a railroad Co. here had some 17000s in their switcher engines that I rebuilt several of them years ago. They had two engines in each switcher engine & powered generators.There was other D17000 engines around here that was used for other power but never did see one in the old D8s.They were a little different from normal the way they were engineered.
We repowered a DW 21 with a V8 92TA

diesel doctor from the acme bb has done a couple of buggies for my brother in-law. once he gets back from salvaging the cat they put in the swamp before xmas. he will post some info.
i have pictures and info sent to me last night from a fellow who put a 8v-71 in a td-24. plus a fellow on the redpower BB put a cummins in a td-24 too.
Heidrick Farms in Woodland, California converted farm Cats with truck engines. I have one with D5B, D6 9U, 977, D7E and D7F parts and repowered with a 1673 Cat truck engine. They had 10 of these tractors built up using a 977 and beefing up the rear ends.
I bought the last one they converted. It had longer track frames then the first nine using D5B undercarriage on 977 extended frames.
I farm with it a little but I didn't think it had all the all the horses awake yet. A truck engine like the 1673 sounds good when you can keep your foot in it.
Dave the 1673 truck engine is just the basic D333 engine that was used in the 977 53A & the D6 44A after the 9U & in a few other applications. It was aftercooled in the truck & a few other changes to make it compatable as a truck engine. The same went for the 1693 truck engine as it was the basic D343 duel overhead cam engine used in the 983 & 988 loaders & scrapers & other applications.
I forgot to add that the 1673 engines depending on the SNs & settings put out from 220HP to a high of 250HP at 2200 RPMs under full load.

wow, the d 17000 conversion to a d8 is great, and its still cat power, wich is important for us cat lovers.

I knew of a RD-4 with an IH 345 or 392 v-8 with a truck 4 speed transmission bolted between it and the original input shaft.It sold at the I&I tractor club spring sale in Penfield,IL last spring or the year before. Things seem to run together anymore. The undercarriage was pretty thin and the engine was stuck as well as having on of the exhaust manifolds knocked off of it. The salvage yard up at Loda bought it and it was still there for a while. Don't know if it was scrapped or if someone saved it.

an other try hope it works now with the widt 800.....
does any one have a picture of the sixty with cat v8 3208????????
04-11-2008, 12:35 AM
I've seen a video of the Sixty/3208. It belongs to an HCEA guy so ask around those circles.
Hey KoO, whats new with the TD repowered with the V12 GMC known as TD-18X2?
The Cat 60 you spoke of is called "Felix" and belongs to Jr. Christian.
Another note, there was some pics and a story of a Cat D-11 down under repowered with a Cat 3512. The unit was to pull a large bottom plow for cutting roots.

Is that a 144 cu in P3 perkins you built into the 15?
Looks real good. :) :)
Please post some close-ups of the conversion.

a Hough Loader with a Chevy 454 and Automatic Transmission coupled in. When it wore out they repowered it with a Chevy 283 and automatic as it used less gas. They compensated for the weight diference with iron weights.
I once knew a guy who would buy up old Cletracs crawlers and put little V-8's and straight 6's in them. He always used the autotransmissions too. He also bought a Tree-Farmer log skidder and repowered that with a V-8.
I've seen 2 TD-15's or bigger with IH school bus engines in them.
Then there is the guy who put a Chevy 307 with a Governor in an "M" Farmall rubber tire tractor.
I was once at a Gas&Steam Show where there was a Cletrac with a Russian Diesel in it.

Deas, does McCoy Special ring a bell?
Think this might be one?
Oz, this link doesn't work, at least on my computer....http://www.piacentini.com.au/
Has it been replaced? Sounds like an interesting company.
04-12-2008, 03:00 PM
the fifteen was like the picture when i bought it, with perkins p3,
i interchanged the radiator and airfilter and drawbarbrackets to a other fifteen i have to make that one more original, the conversion was made in france i think as it has a french build perkins.
i istalled the battery under the hood, cheked alternator and regulator, adjust as much as possible, new clutch disk, mounted oilpressure gauge, wiring and lots more..

Leuk fotojes daar! (Nice photos there) Marcoten! Hier eindigd mijn Nederlands...
(At least you write my name the proper Dutch way, and you'll also pronounce it properly!)
It actually makes sense: Perkins in a Cat, as Cat own Perkins...:) :)
27 years ago we bought a SAXBY forklift from a scrap dealer with 3 cyl P144 (144cu in) Perkins, double wheels at front, and a manual gearbox (H/L, F/R) for use on our apple farm. The Perkins in the Saxby was the same as the one in your 15! (Saxby was/is a French manufacturer?)
Don't ask me how I remember that!
Apart from the gearbox and running gear, we overhauled/replaced just about everything else on it over the next 2 years: Electricals, hydraulics, then the clutch went north, and eventually the engine was overhauled: cracked cyl head. I could load a 1 ton (3bulk bins) of apples at an idle on her, as we overspecked the hydraulic pump.
Every time I hear a 3 cyl Perkins motor, I'm reminded of that forklift!
Now I'd also recall a Cat 15 purring the Perkins way!
Dewets-"clutch went north"...sounds funny, but I guess it makes sense-here in the US, mechanical things "go south" when they die...:o)
04-16-2008, 04:37 AM
If stuff does "south" from here, they end up in Antarctica and become part of the melting ice cap, so you'll never see them again, or able to "fix-em-up" again! :) :)
With it going north, it can only warm up on its travels, and maybe before it reaches the GWN of King of Obsolescence, it will return southward again to be fixed up, or thrown out...

latest pic of the perkins conversion
04-20-2008, 05:45 PM
Here is a diesel-conversion found in Jim Zimmerman's salvage yard at Orchard, Iowa, a few days ago (Monday, April 14, 2008). You will note that someone had removed the gasoline motor from the Sixty, and replaced it with a diesel engine from an RD7 or D7. Also replaced was the radiator, and note the "elephant ears" dashboard that was imported with the motor.
04-20-2008, 05:49 PM
Here are some photos taken in poor light of my diesel-conversion Sixty that Jim Zimmerman recently refurbished. It was a sea of mud outside, so I did not take the newly painted tractor out into the daylight to take photos. However, if you squint hard enough, you can probably make out some of the major features of the tractor.
