How to distinguish between intake and exhaust camshafts in Wuling Hongguang?
1 Answers
In Wuling Hongguang, the letter 'i' on the camshaft represents intake, and 'e' represents exhaust. The main body of the camshaft is a cylindrical rod approximately the same length as the cylinder group. The camshaft is fitted with several cams, whose function is to drive the intake and exhaust valves to open and close. Both the intake and exhaust camshafts are equipped with a drive wheel, which is directly driven by a chain or belt to rotate the camshaft. Camshaft maintenance methods: 1. Inspection of camshaft journal wear: First clean the camshaft thoroughly, then measure directly with an outside micrometer. If the wear exceeds the allowable range, replace the camshaft. 2. Inspection of the fit clearance between the camshaft journal and the bore: Measure the inner diameter of the journal bore with a camshaft journal gauge, and measure the size of the corresponding camshaft journal with an outside micrometer. The difference between the two is the fit clearance. 3. Inspection of cam lift: Position the camshaft as above, place the dial indicator pointer against the cam surface of the camshaft for direct measurement. If the measured value exceeds the allowable value, replace the camshaft.
