jd 2140 hydraulics

[mikeparks]

looking at a 2140 4x4 cab tractor. loader up and down hooked to one set of rear hydraulics. loader is slow up but very slow down. v rake hooked to
other set of rears works fine. any thoughts on what problem could be.

Ind loader valve should be plumbed directly to tractor hyd system not through remotes(scv) and return oil back to hyd ported filter cover for optimum operation.

Hydraulics:
Type: closed center
Capacity: 11 gal [41.6 L]
Pressure: 2466 psi [170.0 bar]
Valves: 1 to 3
Pump flow: 12.4 gpm [46.9 lpm]
Total flow: 10.3 gpm [39.0 lpm]

There is no particular reason that it should not work using the rear remotes, as the ports are the same.

The retract stroke should be faster in all situations.

Perhaps something is blocking the flow such as a crushed line, damage fitting, perhaps someone put a restrictor in one of the fittings.

A valve like this would better suit you better.

Routing return oil to hyd filter ported filter cover should help cycle time.
