    The bucket won't curl a load up, and the loader won't lift a load up. The bucket will tilt down fast and strong and pick up the tractor. If I "point" the bucket down and drop the loader arms it won't pick up the tractor. The relief valve I cleaned and inspected was at the 3pt hitch/tranny casing, not at …

  • Mobile hydraulics troubleshooting, Pt. 2

    Mar 21, 2016 · Other cylinders on separate directional valves, in parallel sub-circuits, are working normally. We'll say that the unusually slow cylinder function provides bucket curl motion on an excavator, and that the boom and stick cylinders are working fine. This sounds like a flow rate problem for the bucket curl cylinder sub-circuit.

  • Hydraulic Problem - Bucket Won't Uncurl - Practical Machinist

    Sep 09, 2016 · Given that you have swapped lines and the cylinder works in the opposite direction as desired, it is likely that the circuit has a piloted check valve in it. I have a woods loader on my Kubota - it will hold a 2000 lb load on the forks with extremely fine control. This is because it has a piloted check valve in the lift and curl circuits.

  • John Deere Tractor Hydraulics Troubleshooting Guide

    Nov 01, 2015 · If the valve is at fault the loader will drop at an even rate and eventually reach the ground. If a cylinder piston seal is leaking the rate of drop will gradually slow and should stop at some point as the fluid escaping past the leaking seal will eventually become pressurized on the other side of piston and with nowhere to go it should at some point stop the piston's movement.

  • Boom falling fast question | Heavy Equipment Forums

    Oct 28, 2017 · Operating two valves at once puts back pressure on the head of the boom cyl to slow it down a tad. There is so much static load on the boom cyl that it really wants to not be up in the air. Like the loader arms, if you let it drop, it takes a little while for fluid to fill the other side back up again, if you drop and then push down, there's a pause before the action starts.
