JD 140 Kohler K321S versus K321AS

Any help is appreciated.

The base of the 140 engine block has NO "ears" that stick out, and the oil pan mounting bolt holes are drilled and tapped UPWARD into the block.

Another type of block has the ears that stick out, and the "ears" have holes drilled fro the bolts that thread downward into the oil pan.

Then, I believe, there is still ANOTHER block that has BOTH sets of holes, and either pan will work. (Some of the blocks are "relieved" from the edge of the crankcase, towards the "ears", so there's no mating surface availabe for the gasket to seal to, if you tried to use the small, short oil pan you require.)

So, that's the area to look at... if it has the correct, short pan, or it is possible to swap the correct pan over to it. Also, (I believe), on the blocks with ears, the ears are may be too wide to fit between the frame rails, but can be sawed off.

Also, dipsticks and the length of the "dipper" on the connecting rod MAY vary between the varies engines.

I'm wondering if a K321S will fit, maybe I don't have the whole number correct, I'll double check on the K321S.

I know the K321AS is correct as it's the original motor in the machine.

Thanks again for the response.
