SOURCE: system creeps down even when tractor is operating.

There are 2 potential problems -
1. Leaking spool on the control valve - rebuild the vale.

2. Cylinder blow-by. Disassemble piston and replace the seals.

To test if its the cylinder - retract the cylinders all the way... remove the hoses on the blind end (non rod end) of each cylinder, and again pull the valve to the retract position.

If fluid continues to pour out of the cylinder - the piston seal is damaged, and the affected cylinder must be repaired.

To test if the valve spool is faulty - disconnect the a and b ports just after the valve. Turn on the system and check for seepage from the disconnected lines (without moving the lever).

Are you using hydralic fluid (not eng oil) in her?
Can you let it run on blocks for a bit - drain and re-fill transmission?

May be sucking air . Check all hoses and clamps between hydraulic tank and pump. Some models had a suction screen in hydraulic tank that when partially plugged will starve pump for oil.

What would cause my hydraulics to keep heating up on a 648g3 skidder?


Friction is usually the cause of hydraulic overheating. Every time the hydraulic oil moves through the system the moving of the hydraulic fluid against the hoses,pumps, cylinders , etc. creates friction. Any restrictions such as valves or filters can be hot spots because of the friction created as the passages get smaller the fluid moves faster creating more friction. Friction = Heat.
I would check the filters to make sure they are clean. Check the valves to make sure they are opening fully. Check hoses for any kinks or pinched spots.Try to operate the skidder at the lowest r.p.m. need for the work being done. Over revving can also cause heat buildup.
Hope this helps.

check all hydraulic filters and check hydraulic valves. Filters is maybe not good or old, hydraulic valves is damaged or soiled. If your model hawe oil cooler check is it clean out and in!
