I've got a 1967 3500 Ford with the SOS trans and fitted with 735 loader & 723 backhoe. Couple questions that I'm lumping into one thread -
1) The tractor does not currently have a trans cooler on it. How hard is it to fit one? As near as I can tell it came this way from the factory - no cooler in the radiator tank, no loose lines, ports, etc. Since I don't have a radiator cooler, I think an oil to air cooler would probably be the best option - easiest would be to just use an regular automotive type cooler but I'm not sure what pressure/flowrate the SOS trans cooler circuit involves and if that would work. Also, where are the ports on the trans to connect to? I haven't been able to find anything that shows where they physically are and there's no random plugged ports on the trans case that leap out at me.
This tractor is used for around the ranch work and doesn't see that much use, but it does get worked hard from time to time and the trans case gets quite hot - probably over 150* outside of the case, so I'm guessing around 250* oil temp - higher than I'd like.
2) The loader/backhoe hydraulic pump is weak. It's a Vickers vane style pump but I'm not sure exactly which one - manual lists several different options. Any suggestions on a good source for a replacement, preferably reasonably priced?
