DOOSAN D1146 DE08 Engine Piston Pin 65.02502-0010 Wear Resistant

High Precision High Durability Engine Piston Pin For DOOSAN D1146 DE08 65.02502-0010

OPERATING PRINCIPLE:

The function 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.

A piston pin is a cylindrical pin attached to the skirt of the piston. Its middle through the connecting rod small head hole, used to connect the piston and the connecting rod, its role is to pass the gas force of the piston to the connecting rod, or make the connecting rod small head drive the piston together. To reduce weight, piston pins are generally made of high quality alloy steel and hollow.

EMERGENCY RESPONSE METHODS

During the driving of the excavator, if the transmission "jumps", the machine should be stopped (or continue to drive) in time, and then find the cause and eliminate the fault. The specific method is:
(1) If there is a "jump" when driving on a flat road, you can stop the machine according to the normal shutdown methods, carefully find the cause, and eliminate the fault.
(2) If there is a "jump gear" when driving uphill, you can set the gear to the low-speed position or the first gear position, and wait for the machine to stop when it reaches the top of the slope to troubleshoot; When "jumping the gear", you should stop the machine according to the action essentials and requirements of the ramp stop, and then troubleshoot.
(3) If there is a "jump" when driving on a downhill, you should move the gear to a high-speed position according to the action essentials of upshifting or take measures of "snatch" (emergency downshift), and wait for the machine to drive to the bottom of the slope. Stop the machine again to check and troubleshoot; if the "upshift" and "gear shift" are unsuccessful or "jump gear" occurs again (neutral gear at this time), the driver can control the engine speed at medium speed (to prevent the engine from stalling) , use the "point brake" method to make the machine slide to the bottom of the slope, and then troubleshoot. If the "upshift", the "grab" is unsuccessful, or the "jump" occurs again (this time it is neutral), and the machine is on the downhill slope again (at this time, the machine will go to the bottom of the slope at a very fast speed" "Dive"), you should quickly stop according to the action essentials and requirements of downhill stop, and then deduct the fault.

One: Whether the pilot _ secondary pressure of the rotary operation is within the normal range (the normal pilot pressure is above 35KG);
Two: The rotary relief valve is damaged, whether the rotary relief pressure is within the normal range (overflow pressure: 280KG);
Three: Whether the rotary main spool is switched in place, and whether the return spring of the rotary spool is broken;
Four: The distribution valve is worn and damaged, resulting in internal leakage of the rotary motor;
Five: The pump body and plunger of the rotary motor are worn and damaged, causing the motor to leak;
Six: Only if the rotation action is slow and other actions are normal, the failure of the hydraulic main pump and the main relief valve can be ruled out.
