Ford 860 hydraulic leak from check valve cover plug, front of top cover
Hydraulic top cover gasket is yellow paper. And I assure you, aside from the crayon circle I drew around the check valve plug that photo is quite authentic. And still no hydraulic leaks. Cheers! -

Ford 860 hydraulic leak from check valve cover plug, front of top cover
The 3pt lift on my 860 finally stopped working entirely after a few years of marginal performance so I took the top cover off and rebuilt or renewed everything attached to it, including lift cylinder and all valves I could access. A bunch of parts were damaged/cracked bent so were replaced with... -

Ford 860 draft spring sitting on bolt heads
A final update on this thread, I took some measurements and bought some multipurpose sleeve bearings from McMaster Carr. For my 1957 Ford 860 the correct part was 6381K361: 2" shaft diameter, 2 3/8" housing ID, 3" length, made in the USA of 660 leaded bronze. They were a tighter fit and had... -

Small PTO sprayer hydraulic agitation
Manufacturers will say that internally, a lot of pressure regulators will not regulate pressure reliably if the bypass is pressurized or has resistance to flow. They will even tell you to route the bypass to the top of the tank (atmospheric pressure) or the inlet to the pump (vacuum/negative...- lka

Small PTO sprayer hydraulic agitation
I can't put them on the bypass since that would cause restriction, but I think I could reroute the bypass to tee into the supply line ahead of the pump inlet instead of into the tank itself and then use the tank bulkhead where the bypass used to go to supply those jet agitators via a separate...- lka

Small PTO sprayer hydraulic agitation
So the sparging bar is your only tank return and is thus also your "bypass", effectively? That's slick and simple but I think that only works with a centrifugal pump, which doesn't need bypass flow. My understanding is with a positive displacement (e.g. roller) pump I can't valve or otherwise...- lka

Small PTO sprayer hydraulic agitation
Hi folks, have a question about requirements/guidelines for agitation for spraying suspensions. I've used small backpack and pump sprayers but nothing larger, and I've never sprayed anything but water soluble herbicides which don't really need to be agitated (and have worked fine for me...- lka

Ford 860 draft spring sitting on bolt heads
Thank you! I will add out that my old bushings are bronze while the new ones appear to be steel, much less sacrificial and more likely to wear the housing. -

Ford 860 draft spring sitting on bolt heads
Just an update, since they are cheap I tried one and a new seat did fix this issue thank you. My replaced lift arm bushings are not super tight in the top cover and rotate a bit when the rockshaft rotates. I needed to tap them in gently but they did not need to be pressed in. Obviously with... -

Ford 860 draft spring sitting on bolt heads
Yes thank you sorry I guess I wasn't clear in my reply. The seat (#4) along with seal (#6) is present. It has wear on the bottom where it contacts the plate (#7). The photo is of the old plate (#7) showing the wear from the seat grinding into it for 70 years. I just didn't want to take the... -

Ford 860 draft spring sitting on bolt heads
Thanks. The "seat" (#4) and the felt seal underneath are both present, it was hard to see that in the original photos. However that is a good point there is a bit of wear at the bottom of the seat, I had to dremel away a partial lip of deformed metal on the inside edge to get the felt seal to... -

Ford 860 draft spring sitting on bolt heads
1957(?) Ford 860, rebuilt my hydraulic top cover and cylinder due to many issues. It is back together but the draft control spring appears to rest on the bolt heads rather than on the spring seat. It is close, maybe only 1/32" to 1/16" clearance off the seat. I think I assembled everything... -

Ford 860, hole in center hydraulic housing
My 3pt lift stopped working so I took the top cover off to troubleshoot. I found this hole/defect at the bottom of the hydraulic compartment, which is odd. A lot of things on this tractor have been butchered by the previous owner who was proud of his cutting torch, but this does look like it...
