Hi Folks
I have a Ford 8N with a forklift attachment. it's been used quite a bit recently because we are cleaning up a pushed over barn so it's handy to have a forklift that can drive through anything. Recently we've had trouble with the folks coming down and I thought it was just crud in the tracks but I think not it has something to do with the hydraulics. When it first started happening we could put a little weight on the empty forks and it would free up and come down normally. yesterday though that didn't work and neither did a loader bucket full of rock. we left it parked with the down lever tied back and it came down on its own by morning the next day. Also while it was stuck I checked all the clearances on the mast and was able to rotate all the cam followers and guide bearings, everything was free.
It has 3 levers one for tilt one for side shift (these are both double acting cylinders, no issues there) The lift cylinder is also double acting but the return (down pressure) side of the cylinder has an empty hose back to the reservoir (small diameter not meant for pressure) and the down pressure side of the valve is hooked to a T on the return side of the hydraulic circuit. I don't see any sort of flow control in the system where a clog could occur but I don't really know what to look for, or where to look.
