How to adjust the valve clearance of BYD F3?
1 Answers
When adjusting, first loosen the lock nut and adjusting screw, insert a feeler gauge of the same thickness as the specified valve clearance between the valve stem and rocker arm of the valve to be adjusted. Rotate the adjusting screw and pull the feeler gauge back and forth until slight resistance is felt. After tightening the lock nut, recheck the clearance. If there is any change, readjustment is required. There are two main methods for adjusting valve clearance: 1. Cylinder-by-cylinder adjustment method: This method only requires turning the cylinder to be adjusted to the top dead center of its compression stroke (at this time, both the intake and exhaust valves are completely closed) to adjust the valve clearance. This method requires finding the top dead center of each cylinder's compression stroke and remembering the firing order of the engine (ignition order for gasoline engines and injection order for diesel engines). 2. Two-step adjustment method: This method adjusts all valves on the engine in two steps. It is simple to operate and highly efficient. No matter how many cylinders there are, only two adjustments are needed to complete the entire process.
