im looking for a 3306 engine for my 95 973 and was wondering if a truck 3306 would work and what I would have to switch over on it or what options I might have besides a direct replacement from a 973.
Thanks

G..G..G..Granville.........!! Fetch your cloth.
There is no "stock" answer to that question.
First it needs the S/No or Arrangement Number of the original engine to establish what spec it is. (It might well be worth starting with this info to establish things like compression ratios, etc.)
Then it needs the same info for any potential donor engine.
With the above the two engines can be compared and a list can be produced of what needs to be done to convert the donor to the original spec.

I would've thought that things like oil pans, front/rear gear trains, flywheel housing, etc, etc might well be different between the loader and a truck application. However they are all "bolt ons" though, and can be swapped without too much difficulty. If you are thinking that an engine from another totally different application will be a simple drop-in then I'm afraid you're mistaken.

Thanks for the information I didn’t think it would be easy but also hadn’t thought about a couple things you mentioned so I believe my best bet is to keep looking for an exact replacement.
Thanks

This was my thoughts too. Got called in once by the owner of a D8H that had bought a D342 engine from a genset to replace his trashed engine... Guess what? the Genset engine had an entirely different crankshaft and could not be used in his crawler. I had already done the homework and backed out. Later he sued a guy that quoted him a price to do the swap not knowing the crankshaft would have to be changed until the engine was on the floor. Even after I told the owner that it WOULD NOT fit.

Very true! I'm just thinking problems with flywheel housing and fuel systems would be very different.
Plus is one a counter bored block and one a spacer plate engine?

I think I'll stop thinking now!

Tried to explain the flywheel flange pattern was different and yes I was the dummy because so and so said it was the same. Guy fell off a ladder and broke his neck, lingered for a week or so and died before the lawsuit really got going. The guy he sued got the machine and engine pretty much for free since the family could care less.

Well can't really click on "like" for that but at least the guy who was getting sued might have learned something or maybe not!

That might be the best solution unless you want a major project and can at least confirm some of the major parts on the truck engine are the same, like block, head and crank.

Not a bad job if one has experience with those engines but sure could snowball in to a major headache if trying it as a first time engine project.

Do all 3306di engines have the same block? Also what about cranks I know some have straight cut gears and some spiral not sure what application normally has what? From what I read they can be changed though?

13739637. I’m waiting to hear back on the model and serial number of the engine I found for a very reasonable price. It’s an 89 model but a farm truck sprayer application not out of a piece of equipment. For the price and the low hours I don’t mind switching everything over that i would need to.

You are correct it’s a z the bottom of the z wasn’t stamped well so it looked like a 7 in the picture I have of the model and serial number.
