D2 Turbo

more power is only any good if you can get the power to the ground and as D2's only have a small foot print this would need to be considered

I think the transmission and final drives would handle the extra power ok as the tracks would slip before any real damage would occur

How ever I wolud just buy a D 4 they arent a lot bigger in size and may well give you the extra pulling power you are chasing with a lot less head ache

Find a D4 or tell your friend to turbo his axx! Dont screw up a good D2!

To make use of the extra power, you have to find extra traction or do the work faster, either way, you mess up a good little tractor, as others have said, find a D4.

Reminds me of a fellow who mentioned to his grandfather, who was an old Cat skinner and mechanic, that he was thinking of turbocharging his D2. The old man replied ' just make sure you have a five gallon bucket, what for grandpa?, so someone can follow behind you and pick up the pieces.

something to think about before bolting a turbo on is the injector pump will have to be adjusted for more fuel and I remember some time ago someone on here started fiddling with a D2 injector pump and it didnt end any good as the specification for the D2 were only held by Cat or some such thing I seem to recall the specs all got lost over time and it was hard if not impossible to restore it to factory specs

I think it was more governor adjustments but be warned of the possible out come

As I have already said I think the little Cat motor and gear box will plenty strong enough to handle the extra power

Well, I have heard enough logical reasons to not do it and that's good enough for me. I really appreciate the knowledge and honesty from everyone. The one I had not really considered is the one about screwing up a good D2, and it is a great little tractor. Thanks for all the input.

Hey Silverstreak,

For the cost to modify a D2 you can get a good D4. If you do spend the $ on modifying the D2, failure is a big risk. I agree that getting a good D4 would be a better plan. Now the next question is? :bump2😄o you get rid of a good D2 or not?:confused2:

A friend of mine just bought 2 D4D orchard tractors. He was telling me they have like 85 hp and a lot of power. I tried to talk him out of one but he wants to keep both. I didn't know they made D4D in orchard model with that much hp. If I could find something like that I would definitely want to sell my D2. I do weed abatement work which includes quite a few orchards and for that reason I need an orchard model. If anyone knows of one that might be bought, please let me know. My D2 is in great shape, just recently painted with new decals, about 6,200 hours on it with no oil consumption, converted to a direct start, grousers and under carriage in great shape. I am the 2nd owner. A fruit grower in Mountain View Ca bought it new and I bought it from his family. He had about 20 acres of cherries and 20 acres of apricots. The tractor has ridge breakers and full width fenders. I think the best area to find an orchard tractor D4 would be in California because of all the orchards at one time.

Hi, Silverstreak.
Turbo-ing - or re-powering with a bigger engine - doesn't usually cause drive train problems unless/until you start adding more load and/or working at higher speeds. If you simply want more power to handle the same loads at the same speeds, that shouldn't be much of a problem - - - - UNLESS you are already over-loading the poor li'l jigger.

Butttt, as some folks here have already said, why stuff around with a perfectly good little D2 when a similarly equipped D4 will give you more power PLUS extra traction for about what you'd likely spend on turbo-ing the D2 and there are NO guarantees that the turbo modification will be successful. As has already been mentioned, governor rack settings would need to be changed and information for doing that is apparently almost as common as hen's teeth and rocking horse manure - - - or honest politicians.

I do like that 5-gallon bucket notion. LOL.

Just my 0.02.
