Skid-Steer loader unloading gravel on a jobsite.

The top two pieces of advice given on every heavy machinery website and on every“ showroom floor” is to always follow the operating instructions in the owner’ s manual and to always follow the prescribed schedule of regular maintenance. However, just like the human body, skid steers are imperfect, subject to wear and tear, and occasionally suffer breakdowns. Even if you are a religious maintenance zealot, unplanned events still happen, especially as the machine ages. What we would like to talk about today is what is probably the most common component that is subject to operational issues on the skid loader— the hydraulics system. We will discuss each type of issue, how regular maintenance can often preempt many of those problems and what can be done when“ unscheduled maintenance” is occasionally called for.

Problem

The lifting and turning hydraulics seem to be sluggish or not working up to capacity.

Fixes: The first thing to do is to check the fluid level. If the fluid is low, the machine is trying to do 100 % of its job with less than 100 % of its resources. Just adding fluid may be all it takes … for now. Check the hydraulic filter. If it is clogged or full of debris, it would be like trying to do heavy exercise with our lungs full of smoke. Also check the hydraulic hoses. If there are any signs of leakage or damage, they will need to be repaired or replaced before any more work is done in order to forestall any further damage to the machine.

Maintenance: Follow the manual’ s guidelines for scheduled maintenance. Check the fluid levels. Ensure that the pump belts are not overly worn and are properly tensioned. Depending on the age of the machine, daily checks may be necessary.

Problem

The whole hydraulic system appears to be operating slowly.

Fixes: Eliminate the possibility of an external leak by checking the hoses. An internal leak may be harder to identify. First of all, verify the system’ s adjustable settings. Systems with variable displacement pumps use pressure compensators and relief valves to determine fluid flow. These may reduce the power to the components to protect the hydraulics. Ensure that the system is set to the manufacturer’ s specifications. If the fluid is exceptionally hot, a more serious internal leak may be indicated. Have the machine serviced right away.

Maintenance: Ensure that the settings are correct during
