V1902 swap to V2203 in 231 Bobcat Excavator.

[Wiam]

I purchased a reefer trailer for storage. It has a working unit on it. V1902 in my excavator has issues. Thinking my cheapest option is to put the V2203 in it. Pretty sure the 1902 has a bad sleeve. I have read on here there are differences between di and idi engines. How do I tell which ones I have? Any tips for saparating compressor from 2203? Excavator is from mid 80s. Reefer is mid 90s

Serials
V2203-227287

V1902-84526

Thanks

It will be stamped on the engine.

Here's a picture of a V2203 that came out of a reefer. See the "DI" stamped before the serial number? If you're running an IDI you'll really appreciate the quick starting of the DI.

There are quite a few differences in the V2203's, but most should work if you can bolt it up.
The V2203's will have a bigger rear journal pattern, this in my case of a swap from a V1702 to a V2203 was just a matter of reworking the rear mount.

The exhaust, and oil pan will be a direct swap, but the intake can get tricky if it's a V2203 late version DI engine as the injection lines will get in the way of a direct intake swap.

On the excavator:
How does the V1902 couple to the hydraulics?
Does the motor drive anything else?
Is there a pump mounted on the back of the Injection pump?

For more engine information look on the top of the valve cover for a white label with information.

No DI in serial on either.
Injection lines look like they will not be in the way.
Hydraulic pump hooks to a splined shaft that I’m guessing is bolted to flywheel.
Does not drive anything else.
Nothing on back of injector pump.

No label on either valve cover.

The reefer motor has a second oil filter that is remote mounted. When I switch timing cover is there any reason to keep second filter? (Have to change front cover as filter would be in the way of motor mount.)

Serial numbers in my earlier post are exactly as printed on blocks.

All I can tell you from the serial # is that it's pre 1997.

Pictures will tell a lot more.

How does the pump attach to the back of the motor?
Is it via the bell housing?
