Mitsubishi tractors have hydraulic assist systems to operate raising, lowering, moving or operating a variety of equipment installations. It does not matter what type of machine your Mitsubishi tractor operates hydraulically, they all share the same basic components: pump, reservoir, filter, high-pressure hoses and fittings and actuated pistons. A hydraulic system is “inline,” which means a problem anywhere along the line of components will affect operation. Troubleshooting problems means knowing these vitals parts of the Mitsubishi tractor hydraulic system.
Lack of Power
If the hydraulic-powered apparatus is not at full power, the first thing to check is the pump and the fluid pressure. Make sure the hydraulic pump power supply and drive belt are working as specified. A slipping belt can cause pumps to not achieve full pressure. Add fluid if necessary but do not overfill. A dirty filter not allowing free flow of fluid from the reservoir to the pump can also be affect power. Replace the filter if necessary. Finally, examine the hydraulic-actuated pistons. Make sure they are not binding or have any dents or other obstructions preventing a full range of extension and retraction.
If the system is repeatedly in need of more fluid, or you see fluid puddles on the ground or on the machine, check all the fittings attached to the pump, reservoir, filter housing, hoses and pistons. Check rubber or other elastic hydraulic lines for pinhole leaks. A small pinhole under pressure can spray a lot of fluid. When a high-pressure line is compromised, it’s best to replace it and not attempt a repair. Also, check the reservoir drain plug for a tight fight. Make sure the pump is not leaking from any seals when pressurized.
If your Mitsubishi tractor is vibrating excessively when the hydraulic system is activated, check all the clamps and mounts. Whether a stainless steel bracket mount or a plastic insert clamp, go around and tighten all the fasteners. Also, check the clamps and mounts when the system is under pressure. Many loose fasteners and clamps are not noticeable unless the system is pressurized and operating.
Sluggish control response
If your control response seems sluggish, check all the connections and control valves operating the system. Make sure the actuated valves than open and close to allow fluid into the system react within proper specifications. A slow valve means the fluid is delayed to the system will not respond quickly to your control. Valves also need to be properly sealed and all fittings leak free.
