Revamping a splitter bought at auction
Splitter was set up to run with tractor wet line...I'll be using a 2N with gear pump on pto
Question!
Am I correct to think that all I need is lengeth of 4" X 3/16 wall pipe to weld pipe fittings onto, to use as a surge/supply tank? This will make the system self contained, to use with any pto .
The splitter has a 4X24 cylinder, and should need a 24" section of pipe as a reserve tank, once the system has purged the air out........tell me if I'm on the right track
Oh, the splitter has had little use and bought it for $200!
 
Within reason, the bigger the tank, the better, more oil = less heating and aeration of the oil.
You might want to go to surpluscenter.com and see what they have for hydraulic reservoirs before d=going through the trouble to build your own, some deals there from time to time, haven't taken a look lately.
 
Yea, isn't there a formula, tank should be 4x as big as the amount of oil used or some such? It needs to be able to settle and get the air out, as well as enough supply to stay cool without a cooling radiator, as well as air space on top to handle foaming, etc.

I'm a poor one to be advising on hydraulics, but I think you want more than 'just enough' oil tank space.

Combine salvage yards are a good place to get a fair-sized hyd tank. Check out the 15 series of IH, or others.
 
I think the rule of thumb is a gallon for every gpm of the pump. I wouldn't want less than a 5 gallon reservoir. Head down to your local farm store with a tape measure and see what new splitters have for tanks on them.

I bought the smallest tank Northern Tool offered. If 3 gallon I would be surprised. Running their 2 stage 16 gpm pump with a 15 hp lawnmower engine on a 4x24 cylinder with their el cheapo splitter valve. I run the tank about half full JD 303 grade hyd fluid with a pressure gauge on the inlet port just for grins.....runs just a few #. Tank is located about a foot above the pump. 1 ?" clear PVC tube supply line to pump inlet, ?" outlet to valve. Always have more than enough left in the tank and supply line never has bubbles or goes dry.
