I have two CAT engs. with "POWER UNIT" 5E4385 and 5E4066 plates on block. These originally powered John Deere no. 36A combines. These engs. had a shaft run back over the eng to run the fan/radiator in the rear of the eng. Question is, to sell these where else might I look besides this forum? John Deere would be the obvious. I tried that but can't talk to anybody without joining/paying which I won't do. Second question is were these type power units used in other equip. These are odd set-ups. Can't be many around so somebody is probably looking.

Floyd Green. I know the 1930 caterpillar no.36 had a flathead Cat tractor engine with the overhead fan shaft, I wrecked a later Caterpillar no.36 50 plus years ago that had a overhead valve engine on it was told it was a Cat 22 engine I don’t know if that was right or not. I think by 1937 or 38 they were putting Hercules JXC engines on I still have a 1941 JD no.36A it has a JXC nice engine I have pushed that machine pretty hard and it always had enough power to keep up, I still have the book on the 1930 model . As I have said before on this board that was one of the most trouble free machines I have ever run, don’t scrap the engines. 17afarmer. Mike

It is not a flathead and that's twice now I've heard the block is same as CAT 22. This means these blocks are not too rare whereas the over top fan shaft set up are not as common. Also I suspect the (very nice) radiators are general purpose industrial units used in various applications. By the way, 17AFarmer, I have various 36A "DIRECTIONS" manuals in good shape if you are interested.

I think John Deere took over in 1935 they changed the B model side hill leveler drives, some of the drive chains, and started using Hercules engines, during the war they changed the turntables and put rollers in them. I think the war production board made them drop the galvanized metal due to war shortages I have a war model John Deere Van Brunt Grain Drill that has black iron side sheets and galvanized end pieces which by the way I still use, I was told those big radiators you are talking about would be at least $2500.00 now. The 41 machine I have got was $3750.00 brand new!

Why would these radiators be so costly? One thing I can say for them is how they were situated in the machine must have put them in a protected space as neither radiator has a bent fin, they're perfect if I remember correctly. Do you know who might be looking for such items?
