OWNER'S OPERATION MANUAL

Hydraulic Surge [Drum Brakes] Hydraulic surge drum brakes have been the boat trailer standard for decades. These trailer brakes are dependable and quick to react, are independent of the tow vehicle, and come on automatically when you press the brake pedal in the tow vehi-cle. As the tow vehicle slows down, the trail-er wants to keep moving.

Here's Your Complete Guide to Hydrostatic Transmission

The hydrostatic transmission is a closed-loop circuit, where the fluid exiting from the drive motor outlet is returned to the hydrostatic pump without being sent to the tank. In this circuit, the input drive is the hydrostatic pump connected to the prime mover, and the output drive is the drive motor which is connected to the load….

Bobcat Loader Troubleshooting

If the loader won't operate correctly, check the hydraulic fluid level. Do not overfill the reservoir; hydraulics work best with the exact amount of fluid in the system. Check the hydraulic fuel filter. If it's clogged and fluid can't flow freely, power to the loader will be reduced.

 · The first step is to determine if the overall hydraulic system is operating properly. If the a loader is installed on the tractor, test the loader to make sure it is still working correctly, which can rule out any problem with the pump. If the loader does not operate correctly, then there is a problem is likey related to the hydraulic pump.

Love Your Loader? Avoid These 13 Mistakes

If the loader will drop by operating the levers when engine is off it does not have check valves to prevent the loader dropping if a hose or valve were to fail. Oh yes, hyd oil burns almost as good as diesel fuel.

The Root Cause of Hydraulic Cylinder Drift

A popular misconception involving hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift. While a leaking piston seal can be the root cause of cylinder drift, the physics involved are often misunderstood. Fact is, if the piston seal is completely removed from a double-acting cylinder, the cylinder is filled with oil and the ports are plugged, the cylinder will hold.

How do you increase hydraulic capacity for a loader

 · NO. The older tractors OPEN CENTER (OC). The oil free flows thru the valves to tank until you pull the lever. From your description, it sounds like your loader valve is closed center (CC), So by tying back the OEM lever, you are closing the OC valve, sending oil to your CC valve body on the loader, and forcing the system to full pressure standby.

The causes of hydraulic cylinder drift

 · Once you achieve equalization, you stop further drift and hydraulic lock from happening again, until more hydraulic fluid leaks occur. Note, some port relief valves prevent a cylinder from reaching equal pressure. This is due to set lower pressure levels. So in the example we just gave, hydraulic drift will continue as overall pressure hits.

Slow Excavator Hydraulics

 · Is the engine bogging down under a load or does the engine pull down farther than it should when you bottom out a cylinder? Proper engine rpm is very important. If its not turning fast enough, your not moving as much oil which will slow your machine down. If it pulls down under a load you could have a plugged fuel filter or air filter.

Locking Protection is Key to Hydraulic System Safety

Hydraulic circuits contain load-holding valves (LHV), also sometimes referred to as counterbalance valves. LHVs are a legacy means used to hold a hydraulic system applied load in place and control its rate of motion. These valves are common safety components of load-carrying equipment and typically a staple of hydraulic safety and control design.
