Ford 555 Transmission no forward or reverse

 · The dump valve redirects shuttle oil (and pressure) to the transmission sump when cycling the loader. There's two switches that control the dump valve solenoid; one on the loader wobble stick and one on the floor. If your dump valve is stuck open, you'll have no pressure and no forward or rearward motion. This is what jimg984 was talking about.

Front

A front-end loader has different movable parts where the hydraulic lines must connect. A combination of hard annealed steel tubing and high-pressure rubber hoses carry the hydraulic fluid to the piston, then low-pressure lines return the fluid to the pump. Make sure all the lines are leak-free.

Transmission Shift Solenoids: Malfunction Problems Testing

Transmission Shift Solenoids. Shift solenoids are actuators used by electronically controlled transmissions to control fluid flow.. Standard on/off solenoids have only two positions, either on or off. They consist of a spring-loaded plunger wrapped with a coil of wire that, when energized, draws the plunger inwards, either opening or closing a hydraulic circuit.

What To Do When Your Transmission Is Overheating

This is what's going on inside your car's transmission while you're driving along. The lubrication system in your transmission is intended to…well, lubricate these areas of friction so that this is never a problem. When your transmission lubricating fluid is scarce temperatures start to rise.

10 Causes Why Your Car is Losing Power when Accelerating

 · They do this by sending in fuel at high-pressure, much like a spray. They need to spray the precise amount of fuel into the chamber for combustion to happen. If there is even a slight miscalculation, the combustion cycle can get disrupted, resulting in loss of power and, in the worst-case scenario, broken cams or pistons.

Common Causes Of Hydraulic Overheating

User improvisation: We often hear of systems that have been running smoothly for years, and now all of a sudden they begin running hot. In many cases this is caused by someone making a system adjustment. One of the more common adjustments made is to the pump compensator to achieve more pressure on pressure compensated variable volume pumps.

The top 5 things that can go wrong with your car's clutch

The pressure plate is what clamps the clutch disc to the flywheel. Since it is one of the hardest-working parts of your clutch, it can become worn out easily. How you can tell: As with your flywheel, a worn pressure plate can also result in clutch chatter. 5. Your throwout bearing might be worn out.

Reasons Your Transmission is Overheating

 · Additionally, pressure is crucial to the overall effectiveness of the fluid. Without enough transmission fluid, there will not be enough pressure for the transmission to operate optimally, and it will start showing signs of trouble, such as slipping, hard shifting, strange noises, and overheating.

Diagnosing Symptoms of a Bad Manual Transmission

 · Manual transmission problems can develop due to high mileage, abuse, or lack of proper maintenance. But they are rather rare. Most manual transmission issues originate not with the transmission itself, but from related components like the clutch assembly, linkage, or driveline: the components that transmit turning power from the transmission to the wheels.

D. May cause transmission torque converter slippage. V. Hydraulic lines and hoses are too small, or are the wrong type. Because of this, they… A. Require additional horsepower to compensate for the pressure losses in the system. B. Create heat, which damages hoses and oil, requiring both to be replaced more often than should be necessary.

Symptoms of Common Hydraulic Problems and Their Root Causes

When fluid moves from an area of high pressure to an area of low pressure without performing useful work (pressure drop), heat is generated. This means that any component that has abnormal internal leakage will increase the heat load on the system. This could be anything from a cylinder that is leaking high-pressure fluid past its piston seal.

Troubleshooting: Common Clutch Issues and Causes

If the spring pressure is not great enough, or the clearance between all the parts is too great, there won't be enough friction to transmit the power from the motor to the transmission. Friction discs wear and get thinner, and springs get weaker with time and use, which is why all clutches eventually start to slip.

Causes of Diesel Engine Smoke

Correct pressure should be maintained in the cylinder chamber in order for proper combustion to occur. In a new diesel engine the rings need time to seat properly and develop an air-tight seal. After a short period of break-in hours under load, the blow-by problem should correct itself.
