3600, right front side, where do these lines go?

The first picture you posted was not your tractor. Is the second picture above of the hydraulic valve your tractor?

I have only posted this last picture and it is the right side of the differential of our 1980 Ford 3600.

I have only posted this last picture and it is the right side of the differential of our 1980 Ford 3600. You can see the square headed level check plug is missing and a bolt that is only a slip fit was stuck in the level check hold some times in the past.

My plan was to plug off these cooler lines but have yet to find if that would cause any short or long term issues. I do not plan to use a loader, etc but just the 3PH hitch lift and the PTO.

I had a 4600 and it did not have the oil cooler. The oil cooler would be a low pressure bypass with a very low flow just to cool a small portion of the oil at any given time. I have a general rule in that I try to restore the mechanical portions of items. I would fix the oil cooler. However, I think either capping off the line or putting a loop would work.

Thanks for the heads up about the flow logic and rate. I am going to store the system since it doesn't leak.

Mid tractor line mounting hardware is missing and the lines shift alot when using the brakes.

Hi, original poster here. I work my 3600 and would like to get this system running again. Anyone have a picture of where the lines originate from?

See post #9 above for my photo. I would like to see a photo of the same location on your tractor to see if the flow has been blocked or has a 6" loopback, etc option. The same basic tractor in 1974 did not have them but did in 1975. If my were OEM like I would not mess with them but since they are a mangled looking mess I would like to have them as I work to restore this working tractor. If it had a loader working off of the main hydraulic pump then yes I can see the advantage. Well the 1975+ have the external hydraulic oil filter so that may be a net heat generator but I do not see that. If I get to mow with my 1980 this weekend I will try to shoot the temp of both oil filters and the exit/entrance cooler lines to see if it has any impact on fluid temps.

The 1976 MF 265 has the same cooler but with better protected steel lines to the front of the tractor but it has the Multi-Power shift option which naturally generates more heat.

Look forward to seeing how they we able to disable your cooler.

Here's what mine has. Not sure if it makes any difference, I'm sure the experts can but mines not actually a 3600. It's a 335 industrial, I just always refer to it as a 3600 because it's close enough and makes the conversation shorter. Mine is the 6x4 transmission. Now looking at where those lines go. That's not a transmission cooler, that's a rear end/hydraulic cooler.

Thanks again. Today I got to ask my local tractor hydraulic guy and he said what you said about it would be fine to plug both at the rear of the tractor. He said the 90 degree block could just be screwed out and plugged with a pipe plug.
