YANMAR 4TNE98 Automotive Engine Pistons For SH75X-3 129902-22080 3 Ring Piston

YANMAR 4TNE98 Automotive Engine Pistons For SH75X-3 129902-22080 3 Ring Piston

Working principle:

The purpose of the piston pin is to connect the piston to the small head of the connecting rod and transfer the gas pressure of the piston to the connecting rod, which in turn transfers it to the crankshaft.
The piston pin is a cylindrical pin attached to the skirt of the piston. The small head hole through the connecting rod is used to connect the piston and the connecting rod. Its function is to transfer the gas force of the piston to the connecting rod, or make the small head of the connecting rod drive the piston together. To reduce weight, piston pins are usually made of high quality alloy steel and hollow.
Emergency response Method
In the process of excavator driving, if the transmission "jumps", it should be stopped in time (or continue to drive), and then find the cause and troubleshoot. Specific methods are as follows:
(1) If there is a "jump" when driving on the flat road, you can stop the machine according to the normal stopping method, carefully find the cause, troubleshoot.
(2) If there is "jump gear" when driving uphill, you can set the gear to low gear or one gear, and wait for the machine to stop when it reaches the top of the slope to troubleshoot; When "jumping gear", stop according to the action essentials and requirements of ramp parking, and then troubleshoot.
(3) If there is a "jump" when driving downhill, the gear should be moved to the high speed position according to the action rules of upshift, or take "snatch" (emergency downshift) measures, and wait for the machine to run to the bottom of the slope. Stop again to check and troubleshoot; If the "upshift" and "shift" are unsuccessful or the "jump" occurs again (at this point it is neutral), the driver can control the engine speed at medium speed (to prevent the engine from stalling), use the "point brake" method to slide the machine to the bottom of the slope, and then perform troubleshooting. If the "upshift", "grab" is not successful, or the "jump" occurs again (this time in neutral) and the machine is again in a downhill slope (at this time the machine will "dive" to the bottom of the slope at a very fast speed), it should be stopped quickly according to the action essentials and requirements of the downhill stop, and then deduct the fault.
1. Whether the pilot secondary pressure of the rotating operation is within the normal range (the normal pilot pressure is above 35KG);
Two: the rotary safety valve is damaged, whether the rotating safety pressure is within the normal range (overflow pressure: 280KG);
Three: whether the rotary main slide valve is switched in place, whether the rotary slide valve return spring is broken;
Four: Distribution valve wear damage, resulting in internal leakage of the rotating motor;
Five: rotary motor pump body and plunger wear damage, resulting in motor leakage;
Six: Only in the rotation action is slow and other normal conditions, to eliminate the failure of the hydraulic main pump and main safety valve.
