Ford 420 rear hydraulic pressure test
I have a ford 420 (70s?) that the rear three point lift arms stopped working. I changed the fluid but seems to be leaking out of the brake pedal shaft but that’s another problem, I guess. Is there a way to test pressure to see if the pump is working before I lift the cover and checks the piston... -

Thanks for all the help so far. Had the pump off twice to clean and reseal everything…took it back off after I decided to replace the transfer pump components. All looked good and think it went back together correctly. Tried to tow start today and have fuel spitting at the injectors and smoke... -

Copy that. I will try. I think I ran the starter for maybe only 10 seconds at a time. If that doesn’t do it, would you recommend taking the pump back off and disassembling the head assembly to blow out all of those bores? Was kind of wishing I did that. Also, i noticed in my pics that the... -

I did tear down then pump. Everything was free and looked to be in good condition. As far as worn, not sure. I didn’t take head anssembly apart but did take out the plungers, cleaned, lubed, and put back same position as everything came out. -

Yes, bled at filter then bled at the pump bleeder while cranking. Good stream coming from the pump bleeder. I have a very small amount from the injectors…not sure how much should be there. But still no start or even trying. -

Still stuck on getting this tractor started. Cranked for three or four batteries worth. Tried starting fluid to get it spinning faster. I do have some fuel dripping at the injectors. It’s a very small amount, though and still won’t start when I try with them closed up. -

Question on the reseal. I match marked the circlip when removing and went back in the same. However, looking at the manual and a couple of videos, the opening of the ring is on the opening of the pump body. The manual states to position in the center in the opening. Should I just put it back... -

Thanks. I can see the tool. Doesn’t seem like it’s available anywhere though. -

Checked the filter seals and the metering valve. Still no fuel at the injectors. Decided to tear down the pump thinking it got some dirt in it doing the throttle and stop shaft seals. Question about the rebuild. Does the large snap ring and governor body need to come out? Bundy doesn’t take it... -

Got it. So, the lip of the element seals on that gasket and the groove in the housing. Pretty sure the gasket is up in the groove and not inside that lip on the element. May be worth checking. However, if I loosen the filter outlet to the pump and have fuel, can I rule this out? Only reason I... -

Fuel filters are NAPA 3166. I had the gaskets out and cleaned everything. Pretty sure I got the gaskets back in correctly (one a little larger on top). I can check though. By top gasket out of place, meaning that larger seals on top and bottom of the filter element? or smaller (1" o-ring) on... -

Having trouble getting fuel system bled and tractor started after draining fuel system. So, here's what I have. The tractor, 70's? Ford 420 with FEL is new to me and was fairly cheap. It ran good and looked decent enough for a project. Finding out that it has been neglected more than I thought... -
