52mm gauge transmission temp oil pressure
The 52mm gauge transmission temp oil pressure is generally a direct sensing gauge. The data fed back by the gauge needle is the pressure of the transmission oil used by the transmission for shifting. During each normal shift, the pressure will change from high to low and then back to high. If the needle shakes violently during normal driving without affecting the normal shift and driving, the main reason is that the oil quantity of the first transmission is not enough, and the quality of the transmission oil has declined. Development information: forklift torque converter plus hydraulic transmission oil. Hydraulic transmission oil is actually a high-quality hydraulic oil, which has higher viscosity index, thermal oxidation stability, wear resistance and higher cleanliness.
While the automatic transmission brings us great convenience, it is also difficult to repair after the failure. The fault diagnosis of the automatic transmission has always been a difficulty in the maintenance of the transmission. Repairers urgently need effective diagnostic tools and methods. In fact, long before the automatic transmission started to use computers, maintenance personnel had a good diagnostic tool - oil pressure gauge, which can be used to check the state of the oil pump, the pressurization of the main oil pressure, the operation of the pressure regulating valve and the booster valve, the lower main oil pressure and the higher main oil pressure, etc. You can even use it to check a crack on the filter screen housing without removing the oil pan! Also, you may not know that the use of the oil pressure gauge can also help you find out whether the use of non original friction plates has caused the upshift impact.If we see that the reading on the oil pressure gauge fluctuates constantly, it usually means two situations:
The filter screen has cracks or the suction end of the oil pump has air leakage. When air enters ATF oil, air can be compressed while ATF oil is incompressible. When air is compressed by oil pump, oil pressure will drop, and when ATF entering oil pump suddenly increases, oil pressure will rise. When this process occurs violently, the pointer of the oil pressure gauge will swing back and forth. The vane locating ring in the oil pump was broken, causing the position of the oil pump vane to move under heavy load. These two situations are usually accompanied by abnormal noise.Some transmissions need to use adapter when connecting the oil pressure gauge, which makes the use of the oil pressure gauge sometimes difficult. But it can help you diagnose the cause of the fault quickly and cheaply.
