Hi guys. I'm new to this community, and I"m not sure if I should be posting this here, or in the Tool Talk forum. Hope it's ok here.
I just purchased a 1975 Ford 4000 SU, and it came with a few implements. One is a home built log splitter that runs from hydraulics. The splitter was running ok for a few logs, but now after raising the ram, and returning the control to the neutral center position, the tractor stalls immediately. It doesn't seem to struggle, or lug the engine while raising or lowering the ram, even when splitting wood. Just instantly stalls when returning to center, and only from the raising stroke.
The setup is:
[list:49ce341876]
* Ford 4000 SU (1975)
* Ford 735 series FEL with a fan pulley mounted hydraulic pump (19 gpm or 14 gpm, not sure yet)
* There's a diverter valve mounted before the FEL controls, which allows me to divert the hydraulics to two quick couplers for implements.
* The hoses from the quick couplers go to a "omaha brand" (D2?) control valve for the splitter.
[/list:u:49ce341876]
I've taken the control valve off and popped out the spool. It looks in good shape - no scoring etc, and I didn't seen any dirt or goober in there to speak of.
One other potentially useful bit of information is that I did change the filter on the hydraulic reservoir a couple of days ago, but I ran the loader for 15 minutes afterwards, as directed, and didn't notice any issues.
I'm a total hydraulic newb, so any help would be hugely appreciated. I certainly don't want to keep fussing with this while stalling the diesel engine on the tractor over and over again!
Let me know if there is any other information, etc. that would be useful.
