Re: New To Me 1966 IH 504

I have searched high and low for a schematic on the transfer block. I cannot find one and nothing is stamped on it to let me know what is a inlet or outlet. Whoever owned this before me installed a pump off the front of the tractor that provided flow for the loader and hoe. This was way underpowered at the hoe, but strong at the loader. It didn't give clearance in the front and was susceptible to damage so ideally I want to use the internal pump. I got rid of the external pump and took the supply hose from the bottom of the flow divider and put that into the inlet of my loader directional valve. I have a 2 spool directional valve with a power beyond at the loader. The power beyond feeds the backhoe and the backhoe return is connected to the transfer block where the flow divider was originally hooked up to. However, that is the only access point to return the fluid back into the transmission and I do not have a way to hook up the return from the loader so the cylinders cannot drain when they are full. I need to know how to hook up a return from both the loader valves and the backhoe valves, my guess is that one of the plugs from the transfer block would also be a return but I don't know which one. I also don't know if I can hook up a tee where I have the return going into the transfer block because I feel like it would just back-feed into the drain/.return from the loader valve which would not solve my problem, or build up extra pressure which could cause other problems. If you can offer any insight from your setup that would be appreciated.

I would tend to think that because of age and care that ruptured steel hose you had was either already cracked or rusted and whatever you did just made it let go. I had a couple lines that feed the cylinders to my backhoe do that. I just did a quick weld and they held fine, but you need to carefully grind down to bare metal



This is on the back of my transfer block. I have no idea where it feeds to.



This is the front of the transfer block, this was originally attached to the bottom port from the flow divider.



This is the top of the transfer block, I have no idea what they do.
