Introduction to Troubleshooting

what is Troubleshooting

Troubleshooting is the primary way to solve a problem.

The purpose of troubleshooting is to determine why specific tools do not continue to work as expected and to explain how to solve the problem. There are many different things that can cause problems with your machine, and no matter what the cause, troubleshooting is always a process of trial and error.

In some cases, the problem may be easy to solve, or it may require you to use several different methods to find a solution. For example, we can use the exclusion method, if there is a problem with the machine, you can use the exclusion method to find the problem, which means you list the things that may be causing the problem and then test them one by one to eliminate them. Once the root cause of a computer problem is identified, a solution can easily be found.

How to Troubleshoot

Black smoke from the exhaust pipe indicates that the mixture is too rich and the combustion is incomplete. The main reason is that the car engine is overloaded, the engine block pressure is insufficient, the engine temperature is too low, individual cylinders do not work or the ignition is too late. When removing, check whether the choke door is fully opened in time, and overhaul it if necessary. After the flame is turned off, look at the main nozzle from the carburetor port. If oil is injected or dripped, the oil level in the float chamber is too high. It should be adjusted to the specified range, and the main measuring hole should be tightened or replaced.

The blue smoke emitted from the exhaust pipe of the vehicle is due to the fact that a large amount of oil enters the cylinder and cannot be completely burned. Remove the spark plug, you can find serious carbon deposits. It is necessary to check whether the oil level of the oil dipstick is too high, whether the clearance between the cylinder and the piston is too large, and whether the piston ring is installed backward; it should be repaired if necessary.

How to Troubleshoot PTO Clutch

The clutch has functions such as ensuring a smooth start of the car, facilitating the car's shifting, preventing overloading of the drive train, and temporary interruption of power. Common clutch failure phenomena include clutch slippage, incomplete separation, start shaking, and heavy clutch separation. John deere electric PTO troubleshooting tends to be rarely problematic. After the free stroke is guaranteed, if the clutch is still not well disengaged or heavy, we will carry out the following judgment methods to eliminate the relevant faults.

1. Remove the cap of the air release screw of the clutch working cylinder, install a hose of appropriate length on the air release screw, and then loosen the screw.
2. Remove the oil reservoir cap and fill it up with the specified amount of brake fluid.
3. Put the other end of the hose in a suitable size container containing brake fluid (above 1/2)
4. Depress the clutch pedal repeatedly, and the brake fluid in the oil reservoir is sent to the master cylinder and pipeline of the operating system. In order to release the air from the working cylinder to the rear engine, a certain pressure must be maintained in the pipeline, and the air pipe must be used.
