5000 Flat Deck Hydraulic Problems/Options

Texas!

My neighbor bought a 1970 5000 Flat Deck SOS with a FEL on it. The FEL control valve is being operated off of a single spool valve with the handle bungeed to the open position. In this configuration the 3PH is non-functional.
What are his options to have the FEL and the 3PH functional simultaneously? I noticed that there is a cover plate on the left rear corner of the engine. Can he add an engine driven pump there since a front mount crankshaft driven pump is not an option?
 
Loader as is must be painfully slow. Adding a pump at the left rear of the engine is not a realistic option as it would not be much faster, notwithstanding the plumbing issues you'd have to overcome.

Best option would be a front, crank driven pump (many are), or else a PTO pump. You should be able to put a front mount pump on it with enough work. Of course, you'd have to come up with a reservoir as well.
 
Wouldn't a PTO pump be about the only option? There isn't any way to mount a front pump on the row crops, is there? No hole in the bolster.
 
PTO pump is not an option because he needs it to run his MoCo and baler. There is no hole in the bolster to run a front pump drive shaft through. When he told me his problem on the phone I told him he needed to get one of those PB plate/adapters. He got one and I went down to help him install it and the first thing I saw as I drove up was the flat top fenders and I thought to myself- "Oh no, we have problems".
 
Any idea of what the oem pump output is on a 5000?
You could... add that side mounted pump from a 3600 and get about 8+ gpm but I don't know if that would be enough increase to justify buying the pump and building a reservoir.
I think I would pull that side cover off and look to see if there is a gear in there first though.
Might not be one.
 
Using a 2 spool aux valve might solve the problem but, finding the 2 spool lever linkage for a 5200 would be a challenge. New would probably be cost prohibitive. Salvage yards?
 
Oops, I didn't catch the flat deck part.

No hole, really? Could one be drilled? I'd be looking into that as a possibility. Cast iron drills fairly easily.
 
Never mind. I just realized that a steering motor sits in there. A front pump is out of the question.

With this particular tractor, if I had to have faster loader hydraulics, and a PTO pump was not an option, I'd look into mounting a 10-series pump on the left rear of the engine, assuming clearance is not an issue. Problem is, it won't be much faster than the pump that's now running it.

To solve that, I would combine the flow of the trans pump and the engine pump into a separate loader valve with integral relief valve. The engine pump would have to use the rear axle as its sump, so plumbing would present some issues, not insurmountable however. I've done something very similar with a 4600 in the past.

One more thing: The gear needed to run the engine pump is likely not in there, requiring a split to install it.
 
Thanks for the replies.
Loader speed is not an issue. Having FEL AND 3PH operating simultaneously IS the issue.
I'll pull that plate off and see if the drive gear is there but I'm not getting my hopes up. If it is there we would add a reservoir to feed that pump and the FEL.
 
I haven't worked on many 5000 flat decks, so I don't recall what kind of real estate is near the pump location, however, if I were you, I'd look at a 10-series pump and note what kind of fuel tank clearance is required before ordering one. Ford actually "smashed in" the corner of the fuel tanks on the 10-series tractors for the required clearance, at least on the straddle-mount tractors.

As for loader speed, my gosh, I could not imagine operating a loader with a 6 GPM pump. I'd sure look into combining the two pumps if at all possible. As I said earlier, you'd have to use the rear axle as a reservoir if you did that.
 
I have a '73 S-O-S 4000 with the pump on the side of the engine and everything I can find says that it is a 5.3 gpm pump, and I run my loader off of a power beyond plate. It's a little slow but not painfully so. It's about the same lifting speed at 2200 rpm engine speed as the loader on my Kubota BX25D with the engine on the Kubota running at about 2000 rpm. If I crank the Kubota up to 2600 rpm then it is faster but not by a whole lot.
