Thank you very much for your time in responding, much appreciated. Just for information the tractors a 1970 135 with the perkins 3 cylinder diesel, she’s done 4073 hrs. So I put it all back together, the oil seemed in good shape so I tipped that back in (might change it one day). You were quite correct the valve, with a little nip from a pry bar slides of the stack pipe without any problem, not sure why it was so stuck on the first time I took it off. The pipe O ring seems in reasonable shape, but the back-up washer, well I didn’t see one of those (it might have been there, but it’s not now). The stack pipe, you can grip the end with ‘long nose pliers’ pull it up, maybe an inch until it hits something, I’d assume that’s the PC (Pressure Control?) feed that stops it pulling right out. You can twist that pipe maybe 20 degrees left to right and it’s takes a little jiggling to get it to seat back down properly, but once it’s in it’s drops right down no problems. Being a diesel you leave the stop out, I moved the position control lever to transport, then cranked her over, but no oil was coming from pipe. So I started her up, expecting oil to hit the cab roof, but nothing. I’ve played with all the levers, draft control, position control and the pressure selector, but nothing. It’s as though the pumps just asleep. Having tapped the diverter valve while it was still attached to the stack pipe, I have a sinking feeling I’ve damaged something. If the PC is attached to the stack pipe, could I have broken something on the PC feed, might a damaged PC feed cause the pump to malfunction? I really can’t think what else it might be. From when it was working fine till it stopped, the only thing I fiddled with was the diverter valve and the stack pipe it was connected to. That 2BA socket, I must get one of those, I have a weak spot for tools. So the opportunity to purchase yet more, is one that I just can’t turn down. I’m just not 100% sure where this plug hole is located to reset the response control, I’ve still got to get the tools none the less :-) Mike,, I think that might have been my trouble to start with. The log splitter sit on the three point linkage, you raise it up to working height then switch the oil flow over to the log splitter and put it into constant pumping. After 20 minutes or so you find the lift arms have lowered slightly, so rather than switch the constant pumping off, then change the diverter valve back to the lift arms I was just flicking the diverter valve quickly across then back again, which is probably what started the leak in the valve in the first place (bloody amateurs). Might just try adding a picture of her
