The inspection steps of York connecting rod deformation:

Install the York connecting rod cover on the connecting rod (without bearing), tighten according to the specified torque, and install the repaired piston pin. Set the connecting rod bearing hole on the prismatic support seat of the tester, and adjust the adjusting screw at the shaft end to make the centering block on the prismatic support seat stretch out. Secure the connecting rod to the tester. Fit the V-shaped surface of the three-point gauge of the tester against the top surface of the piston pin, and observe the contact between the three measuring points and the test plate. the

If the York connecting rod is neither bent nor twisted, the three measuring points of the three-point gauge should all be in contact with the inspection plate. On the contrary, it indicates that the connecting rod is bent. At this time, the gap value between the measuring point and the plate is measured with a feeler gauge, which is the bending value of the connecting rod on the length of 100mm.

Appearance inspection: The bearing cover and the bearing seat should be tightly sealed, the joint surface should not be damaged, and the positioning groove should be intact. the

Check the York connecting rod bolts and nuts. If the gap between the bolt and the nut is too large, there is obvious looseness, the bolt has cracks or obvious defects, the bolt is elongated or deformed, and the thread has more than two teeth damaged, all these need to replace the connecting rod. the

Use a feeler gauge to check the gap between the two ends of the big head of the York connecting rod and the crank arm, and the size should meet the regulations.
