3 spd / HP Fluid Coolers

What does everyone do when these 50 year-old heat exchange units also exchange fluid? Do you open them up and re-core them yourself? Take them to a radiator shop? -thanks

I've bought a few of them on eBay. If you watch, they come up reasonably regular and don't bring all that much. You can get any of them to work, all the way through the whites, so it's not that hard to find a good one if you look a little. Most people never cleaned them, so they were generally pretty well preserved by a giant layer of grease and dirt.

Early Hydra-Power drives had the heat exchanger on top of the unit where coolant from the engine ran through the exchanger.   Late Hydra-Power units had a coolant radiator in front of the engine radiator.

All 1550 & 1555 tractors were Hydra-Power only.   I have seen earlier tractors with a automotive transmission cooler from a parts store plumbed and mounted in front of the engine radiator, simple fix.

Thanks very much for the info. I like putting a trans cooler in front of the radiator. I guess they started doing that in '69 or so with the 55 series? Meanwhile good to know that the old-style coolers are on ebay now and then, I will look for one too.
