garbage truck pump on logsplitter

...but would like to find a knotty crotch...

The garbage truck pump idea is out. I disconnected the shaft at the engine today, and it free spins way too easy, no resistance at all, and would have had to be mounted on the front of the engine. I went to Northern, but they are out of stock until september on a Haldex Hi pressure cast iron gear pump in a CCW rotation. #10586-1201 The only reason I don't just go and get a 28 gpm 2 stage is because I would then have to source another 16+ hp small engine, and pay almost 400 for the pump itself. Besides, who doesn't like a challenge and having the baddest splitter in the neighborhood. Going to see my local truck body fitter tomorrow. Came up with a good way to get a shaft on the back of the engine. I sourced a flywheel, clutch assembly, and manual transmission from the back of my shed for an older ford truck with this engine. I torched off the imput shaft as close to the bearing in the front of the trans as possible. installed pilot bearing in crankshaft. Put peice of shaft with splines thru clutch disk, and welded a washer on the pilot end just at the beginning of the splines to keep it from pulling out. Installed clutch on motor- have a dead center 1" shaft out the back of the Ford. I will grind a keyway into it, and install an L110 1" half on it, and the match on the pump. I would have pictures, but have no AA batteries. Tommorrow.

That pump will need 128 HP to run it, and develop the pressure and GPM's

Which way does the engine shaft turn, that you will couple the pump to?

The engine turns ccw, so I need a CW pump, if I am thinking correctly. I am going to go back to the salvage yard, and get the oil cooler off of the truck.

Yes, if you mount it shaft to shaft. The pump should turn opposite the engine rotation.

If you mount it side by side on the shaft end, the CCW pump must turn in the same direction as the engine if the shafts are facing the same direction.

A clutch pulley hyd pump would have to turn CW.

Good, because the cw pump is in stock, and ships today. Looks like I will have this done this month yet.

Is there something better to use for fluid than Dex 3 ATF. I run it in everything other than the ford tractor, it gets hyd 32. As far as hoses go, I would figure for heat dissapation, I should go with the size that comes out of the valve and adapt down to 3/4 at the cyl. The valve has 1-1/4 ports. Or, for burst resistance, should I adapt to 3/4 right at the valve so I get a higher psi rated hose? Suction line and Discharge/cooler linews will all be 1-1/4. The only one i really worry about is the line from the pump to the valve. 3/4 for pressure resistance, or 1-1/4 for flow, or something in between? I really don't want a hot oil bath, and trans fluid is expensive enough without having to replace it. Burst a hose on this thing, and it will empty the 30 gallons in the system in less than a minute.

Many questions, but I really appreciate the guidance. UPS says my parts will be at home tomorrow after work

Use whatever size the pump uses for suction, and for the pressure hose, use whatever size is on the pump pressure port. Use reducer fittings for the valve if necessary .

You can specify the pressure you want on the hose.

Use Teflon paste/tape to join the fittings if NPT. Don't forget the return filter.

The largest log splitter valve I have seen is the 25 GPM log splitter valve.

Dunno if I'd call it better but it's cheaper, AW32
Hose sizes, as JJ said. If you're worried about bursting, go with a 4 wire hose for the main pressure line. It'll be costly and a lot stiffer but chances of bursting are a lot lower.....Mike

Ok, So I went with 1-1/4 suction as that is the size of the pump inlet. I went with 3/4 line for the rest, because that is the size of the outlet. THANK YOU ALL for your help. pictures and updates are and will be posted in the made it myself forum under homemade logsplitter.
