Chery a5 Valve Clearance Adjustment

According to the introduction of Automobile Maintenance Technology Network, Chery A5 is a medium-sized car produced by Chery Automobile. It is equipped with 1.6L or 1.8L ACTECO engine and adopts overhead camshaft valve train. It is necessary to check and adjust the valve clearance regularly to ensure the normal operation of the engine. Chery A5 valve clearance adjustment method is as follows:

Before adjusting the valve clearance, remove the cylinder head cover so that the cylinder 1 is at the compression top dead center position, that is, the "UP" mark on the camshaft sprocket is aligned with the top edge of the cylinder head.

Select the appropriate feeler gauge (thickness gauge) according to the standard valve clearance. The standard valve clearance is: intake valve 0. 15~0. 19mm, exhaust valve 0.26 ~ 0.30mm..

The secondary adjustment method (double-row non-entry method) is adopted, that is, all valves are adjusted twice. During the first adjustment, the intake valve and exhaust valve of 1 cylinder can be adjusted; 3-cylinder exhaust valve is adjustable; The intake valve and exhaust valve of cylinder 4 are not adjustable; The 2-cylinder intake valve is adjustable. During the second adjustment, the crankshaft is rotated once, so that the cylinder 4 is at the compression top dead center position. At this time, the intake and exhaust valves of 1 cylinder are not adjustable; 3-cylinder intake valve is adjustable; The intake valve and exhaust valve of cylinder 4 are adjustable; The dual-cylinder exhaust valve is adjustable.

When adjusting, loosen the lock nut and adjusting screw first, insert the feeler gauge between the adjusted valve foot and rocker arm, adjust the valve clearance by rotating the adjusting screw, and pull the feeler gauge back and forth until you feel slight resistance. Check again after tightening the lock nut, and readjust if the clearance changes.
