Ford 641 front hydraulics disconnect question

[gemutlich]

Gents,

Hoping to not spend another Winter where I'll be tempted to use this beautiful Dearborn model 19-3 snow plow again.

Plan is to put the plow and all it's periphery up for sale, to be replaced with a proper bumper to help keep us from even thinking about putting anything back out front again, lol

Ok, so the question I have is: How do I remove the hydraulic lines from where they attach where the lift lever is just in front of the seat and plug or cap the tappings in that valve block (nomenclature?) so as to not cause any damage to the pump or anything else in that valve block?

There aren't quick disconnects, so I'm guessing I could just use pipe plugs for what looks to be 1/2" NPT? I'm just concerned about blowing anything out internally if I plug those tappings and someone moves that lift lever with the tappings plugged.

I guess another approach would be to eliminate that lift lever and vale assembly altogether, but what the heck would I replace it with?

Sorry for the elementary grade question, problem is I've only ever known this tractor to have that plow mounted up front even when the tractor was being used for bush hoggin.

Thanks fellas.

It appears you have a dual acting single spool valve that probably runs a single cyl up front..correct?

That's a nice 200-409$ option on your tractor.

Also looks lil short stub hoses come out of it and go to longer hoses. You can remove the longer hoses and add quick disconnects there.

Then when you need a remote... You got one.

And yes, alternatively, you COULD, just plug the ports in your valve block.

Yes, operating the valve with ports blocked will load the engine and open the relief valve much the same like holding the remote open against a cyl at max stroke.

The relief valve will protect the system for intermittent use. Thus accidentally kicking the lever won't hurt.. Holding it against relief for linger periods, however will heat the oil, and load the system needlessly.

Yessir that's correct, single cylinder up front.

Short hoses connect to steel tubing, steel tubing runs up under the chin where short hoses again connect at the lift cylinder.

Quick disconnects sound like the way to go, may never need a remote connection but... Lol

Thanks for jumping in, SouNdguy. Can always count on you.

Or ,if not needed, you could just take the valve off and sell it with the plow for more money and put an original style plate back on. I have sold plows with valves and usually the buyer is more than happy to give you the plate, which he will not need anyway.

Heya Kirk, thanks for jumping in, always good to hear from you man.

You're right about that, I mean what good is a plow to a guy that doesn't have the valve to operate it?

Question: Is the front mounted snowplow the only attachment that these underseat valves were used for? I could see needing a 3-point side-bar mower later on, and if this valve could be used to hinge the mower up to perpendicular and down to parallel then maybe I should keep it.

 

[Soundguy]

those top cover remotes were used for MNAY things, loaders, plows, etc.

if you ever think you will need the hyds, keep it. it will cost you more to replace it later on, than you will make by selling it with the plow.

The person buying the plow could operate the single cyl off his 3pt hyds by chaining his rear arms down.

Roger that, it's like you're a mind reader sometimes souNdguy.

Any idea what this lever and these little 1/8" pipe plugs are for on the right side of the top cover remote?

 

[Soundguy]

the lever could be fast drop to use as single action.. the small plugs are probably just plugging ports where they drilled to manufacture the valve.

 

[gemutlich]

Roger that, kinda what I was thinking about those plugs. The lever I figured must be for flow control but was still a head-scratcher. Thanks souNdguy :thumbsup:
