I have a case 850D 4 cyl motor for sale. It is ready to be reassembled. Less 1 oil pump. Bought from a machine shop extra for the dozer we had. We sold the dozer before we needed to use the motor
850 D had a six cylinder 5.9 Cummins
No motor is 4cyl
Could your motor be out of a 850 B The case online parts site list a Cummins 5.9 in an 850 D
Some early 850's were actually tagged D850 (diesel) @Kellyakers1 does it have a single 4 cylinder head or 2 heads?
My 850D has a straight 6 Cummins 5.9 in it. That's what they all come with. The only option is if it was equipped with the turbo or not. I think the 850C has a 4 cylinder, but not sure.
It’s a 4 cylinder two heads on it
It’s 4 cylinder it has two heads on it
Here are some pictures of it. My dad had a 850 case dozer it was around the 80’s models. He bought this for our dozer but he passed away and my mom sold the dozer a couple days before he passed. I know he got it from a machine shop
Pics of the motor I have
Case 850 dozers had Case 301 four cylinder motors. The 850B had 336 four cylinder motors. The one in your photos could be a 301 or a 336 cubic inch. The Case 850D was the first 850 to have the 6 cylinder motor.
Is there anyway I could check and find out for sure. Like I said my dad bought it from a machine shop for our dozer. Unfortunately my mom sold the dozer a few days before he passed. So now I got a good motor but don’t have a dozer
Remove one of the heads and measure the cylinder bores. From what I see in the photos you have a lot of junk parts. The injector pump is worthless along with everything else that was not sealed for protection from contamination. The rust in the dipstick tube in the block also indicates a disaster as far as “reassembling” the motor. Good grief even the oil pan is not on the block to protect the crankshaft The block does have some value if it was stripped and cleaned up, provided it isn’t damaged.
I thought from the photos these were the original engine torn down, improperly stored and there was another engine to install. If the photos represent the replacement engine, Tinkerer is very correct to value. Not much of anything is going to be usable without rebuild and that will be a lot of $$$ to do on short order. IMO probably best to cut your losses and either scrap the items, or if you have time, break it open as suggested and measure it up to ascertain what you actually have, then hit ebay, craigslist, FB, etc. to sell parts. What you have now is worth what it will bring across the scales.
There should be a sticker on one of the valve covers that shows the model number and valve clearance settings. There is also should be a tag on the block with serial number and model number.
