New tractors are running a higher pressure in the hydraulic system then a few years ago. Husky has been getting calls to see why the oil is getting hot or the closed center Hydraulic system is pumping all the time.Here is whyThe relief valve is set for 25oo psi and the tractors are putting out 2900 psi. so the oil is going over the relief valve all the time.

How to fix
Turn in the relief valve all the way. This will still give you protection from 3300 psi. 1. Loosen the jam nut on the relief valve.( it is located on the right side of the levers on valve bank. )2. Use the set screw & turn it all the way in clock wise.
Please call the Husky Factory if you have any questions at all.1800-349-1122
