FEL Hydraulic Line Routing

[Tom_Veatch]

When the FEL on my tractor was installed, the line from the pump was cut, bent outward away from the chassis, and plumbing for the FEL was inserted. Straight fittings were used and all seems to work well.

However, there is an interference that correcting will require replacing the straight fitting with 90 degree elbow fittings. I don't think the flow rate in this system (which isn't mentioned in the manuals I have) is high enough to cause a significant pressure drop across the elbows. But before I step off the cliff in a blind leap of faith, I thought I'd touch base here and see if there's any reason that might not be a good idea.

I'm also thinking about putting in some quick disconnects to make dismounting the FEL a little simpler, should the need arise. I know about the dead-heading problem and am thinking I'd have a short length of hose made up to bridge the gap if/when the FEL comes off.

I'd appreciate any comments, alerts, cautions, and warnings you might want to throw my way. Consider that my knowledge of hydraulics is pretty much limited to knowing that pumps, hoses, valves, and cylinders are somehow involved.

Also, the coupling nuts on the fittings are .75" across the flats. Is that enough information to define the nominal sizes of the fittings?

I've used Koykers' 12mm 90° fittings with quick disconnects without any problems on a few FEL installs. No problems at all....as long as you never forget to immediately bridge the couplings with the hose BEFORE you start your tractor.

The fittings ran about $17.50 (each).

I have quick disconnects on my tractor and have a short hose to use when the FEL is disconnected.

Notice I plumbed the connections using one male and one female connection on the fixed mount. This facilitates getting the hoses hooked back the same as they came off and not reversed.

Opps, this pic was taken before I made the change to couplings.
