The
camshaft wipe, inspected for cracks, camshaft (camshaft) whether there was cervical scrapes, keyway for wear and distortion. If damage should be repaired or replaced. (1) camshaft bending the inspection. If the cam fixed to the lathe chuck, and with the dial indicator to check the concentricity of the camshaft, allowing the limit of 0.01mm. The camshaft placed flat on both ends of the journal V-shaped block, the magnetic dial indicator contacts the table and the middle seat of the journal surface contact, and then slowly turn the camshaft week, on the dial indicator reading The difference, is the journal of the ends of the middle of the radial circular bound journal error, using the limits of its curvature Santana and Jetta as 0.03mm, Beverly is 0.025mm (swinging the hands on the dial indicator as 0.06/0.05mm ), or should be corrected, the same methods and calibration crankshaft. Camshaft adjustment, the middle of the radial circular bound of the journal should be not more than 0.03mm. (2) journal of the inspection. Measured with a micrometer diameter camshaft journal, such as the cylindrical cam journal wear the error is greater than 0.015mm, replace the camshaft. Camshaft bearing clearance inspection methods and the same crankshaft radial clearance. If the gap is too large and should be replaced bearings. Camshaft when the axial clearance measurement, should be required to remove the hydraulic tappets, install the 1,4 (or 5) Road, bearing caps, fitted with dial indicator, camshaft the allowable limit of the axial clearance 0.15mm .
