Hydraulic lines

Bkpigs · Mar 11, 2018

Planning on replacing the hydraulic lines on my Dunham-Lehr 22 loader. The PO used some 1/2" and some 3/8" line. The cylinder fittings and the block fittings are all 3/8" but typical Pioneer couplers use 1/2". The 3/8" looks like what came on it originally according to the hose clamps. Would there be that big of a difference in going with the 3/8" compared to 1/2"? The loader is on a Farmall 504. I would prefer 3/8" since it is cheaper and more flexible.

Any 3/8 fitting or cylinder connection threads in a circuit restricts that circuit to that volume. The 3/8 hoses do slightly restrict flow in addition. I would use the 3/8 and live with it. Jim

Run 3/8. For all the hydraulic capacity a 504 has,
you?ll never need 1/2? hose. I don?t think many new
loaders today use 1/2?.

Isn't the conventional wisdom to use 3/8"
hoses with 1/2" quick connectors, valve
blocks etc, to maximise flow? Always worked
good for me on small machines. Jim
