Hydraulics modification

(This question is for the inventors, not the purists.) :P :P :P

I'm curious if anyone has modified or seen pictures of modifications, to run a 2nd hydraulic pump off the front of a Cub engine. I have one idea in mind, but before I start making it, I'd be curious if anyone has pictures of such an invention.

This of course is not a Cub engine but an example of what I mean:

I saw a modification very similar to the picture you posted except it was a York AC compressor on the right side of the engine to keep the farmer cool on his stool in his cab. I believe it was an IHC as well.

The only thing which struck me as odd was there was no provision for belt adjustment. The belt length required was measured then bumped on or railed with a screwdriver or something.

The fab guy claimed building an adjustable platform was way too complicated so when it starts slipping 3 bucks tightens it. (70's or 80's prices)

The cab air did work well. I had occasion to borrow it for a few days in trade for charging the system.

Sounds cool !

It was... Even cooler when R-12 was around a buck a pound.

Keep in mind the AC was on a Diesel and it did drop the RPM a little when it cycled on. Since the cub is a little low on the HP scale, factor in the work you intend to do with the pump.
 
Years ago, Farmall A (?) had a power steering pump mounted on right front of engine. Hydraulics for raising and lowering mower deck. Was church owned. Power steering pump had a pretty good sized reservoir, probably off a larger truck.
 
Space constraints make it very difficult to mount a belt driven pump (or anything else) to the C-60. The generator location is about the only location that the belt would have a clear run to. I used a BMW power pump to power the hyd. system on Cubota but it's Kubota engine is an entirely different deal.

Years ago, my brother installed a Ford power steering on his Farmall B, as a lift pump for his cultivators, to replace the exhaust lift. When he restored the tractor, a few years ago, he removed it. Now, he's considering putting it back on.
 
I used a Prince pump on the PTO of my "H" years ago to run my log splitter. Might be easier then a pump of the engine.

Bod a double sheve crankshaft pulley would be a great drive point. (found on some combine power units). Ed

You have one for me?

I'm thinking of taking the alternator down, outside of hood, essentially the alt. and pump would both be outside hood.
 
Electric powered hydraulic pump. I have grain truck hoist powered by 12 volts directly connected to battery. Controls are a hand held push button. The hydraulic pump, electric motor, and reservoir, are approximately 14 to 18 inches long and about 12 inches tall. This system is single action - up. Haven't researched the topic. Probably double action systems available.

Edit: E-bay has some 12 volt powered hydraulic pumps listed. Worth considering, might be the least expensive way to go.
 
You need to stop by Lonnie's across the street from me. If you want to build something he knows how to. Great guy...awesome shop....fabrication skills beyond believe. All the local pullers are having him build their tractors.

1941 Farmall A with 1000 Loader!

This should solve some of the questions about an outboard pump on a Cub. Although the Cub has a smaller engine - it should work. I have heard of others using fan hub powered pumps on Cubs before and it kinda makes sense in a way. However, the only way to know for sure is to well, try it.

and this thread might be useful as well

That pump was used on the Cub PTO but should fit up front.

Industrial Fluid Power, Womack Educational Publications. Appendix C, "Drive Horsepower for Hydraulic Pump".

1500 psi at 85% pump efficiency. 3 gallon per minute pump takes 3.09 HP. 5 gallon per minute pump takes 5.15 HP. 7.5 gallon per minute pump takes 7.72 HP.

1250 psi pump at 85% efficiency. 3 gallons per minute takes 2.57 HP. You can use the previous figures to approximate the HP required to power what ever pump you obtain.

Simply idling the pump at zero psi takes approximately 5 percent of the pumps maximum rated horsepower.

Depending on intended application and proposed usage, the Cub engine may or may not be up to it.

Have you considered mounting it to the front bolster and driving it through the crank hole, directly off the crankshaft?

This is how many loader hydraulic pumps are hooked up. Old ford and Fergusons with aftermarket loaders, were done this way. My IH 444 has a front pump. Ed

We owned a TO35 with a Lord loader on it. It had the shaft that went through to the front pulley to drive the hyd pump however the end of the shaft "keyed" to fit in the end of the crank pulley tightly and centered. I don't know what is available to be able to do that with a cub. I'd be a bit concerned with a shaft that could be a bit off center or loose whipping around. I'm also concerned as to what's out there to support the pump on.

I think a shaft, long enough to reach the center hole on the crankshaft would center well enough. A cross pin would drive it, from the crank pin catch points. A bracket could be fabricated to attach to radiator mount bolts on top and the axle pivot bolt on the bottom. Bob is quite a crafty varmint, although I wouldn't admit to saying that! Ed
 
Bob,

Another few options. First would be to move your voltage regulator and coil and mount a small pump under the generator. I think the coil needs to move to get the lines though. This is assuming you just need a small pump and can use a bypass block with the existing hydraulic system. My second thought would be to remove the entire air filter assembly. You would need to put a small clamp style air filter directly on your carb. You'll then have a vast amount of room under the hood, plenty of mounting points, and may be able to use the existing hole in the hood for a fill point on a pump with a tank.
