1 link maintenance inspection
Step link deformation test:
A cap is mounted on the rod linkage (without bearings), according to a predetermined tightening torque, fitted good repair a piston pin.
The link set in the bearing holes supporting prismatic base prover, adjusting the adjustment screw shaft, so that the centering seat supporting the prismatic block flared.
A connecting rod fixed to the prover.
The V-shaped surface of the three-point regulation prover abutment pin in the top surface of the piston, and to observe the three-point contact with the inspection plate case.
If neither bent nor twisted link, then three gauge three measuring points are to be in contact with the test plate. Otherwise it indicates that the link has occurred bent, this time with a feeler measurement points measured value of the plate gap, i.e. the value of the link on the degree of curvature of 100mm length.
Detection of the appearance of
bearing cap and bearing should adhesion, binding surface without injury, positioning slot intact.
check rod bolts and nuts. Such as bolts, nuts cooperating gap is too large, a significant Songkuang bolt obvious cracks or defects, stretching deformation or bolt, the screw has two or more teeth which need to replace damaged link.
with a feeler rod big end with the crank arm both end faces of the gap, the size should be specified.
