4650 hydraulic leak

[Kchunter]

Recently purchased a 4650, was using it on a hydropush spreader. Noticed oil dripping near the front end. Looks to be coming from the bottom of the hydraulic pump, maybe the stroke control valve. All the hydraulics seem to be working properly.

Hyd leak could possibly be seal on stroke control valve adjustment screw. One can replace seal but hyd stand by pressure needs to be checked with a gauge. Pressure should be 2250-2350 psi.

Where should I check the pressure from?

It could be a broken plastic pump cranckase drain line.
But this isway too dirty to diagnose. This needs to be seriously presdure washed first.
