1450 engine securing/mounting bolts fell out

The flat pan is for the 10 hp K241 engines. You can't use those on the 12-16 hp engines. You need the deep sump pan from a Cub Cadet-spec K301, K321, or K341. I'd look for a cast iron pan instead of an aluminum one.

Good to know. Thank you!

Interesting. Are the cooling properties the reason that some of these machines were fitted with aluminum pans? I was wondering why IH would go with such a soft metal for a part that is used to secure the engine.

A bare aluminum pan will transfer heat to the air better than a cast iron pan. This will slightly reduce the oil temp. I doubt the difference is enough to matter.

The aluminum pan was likely a manufacturing cost savings.

I don't know how true this is but, some of the reasons for switching to aluminum were manufacturing costs and the cost of meeting pollution standards for cast iron at the time. So, then came aluminum rear ends, and more.
