What is the method of BYD f3 valve adjustment?

BYD f3 valve adjustment method: 1, cylinder by cylinder adjustment method. First, loosen the adjusting screw, turn the screw shaft with a screwdriver, and then tighten the screw to adjust the gap between the intake and exhaust valves. 2. Twice adjustment method. When adjusting, while screwing the adjusting screw, insert the thickness gauge between the valve stem end and the rocker arm and pull it back and forth to feel slight resistance.

When adjusting, loosen the lock nut and adjusting screw first, insert the feeler gauge with the same thickness as the specified value of valve clearance into the gap between the adjusted valve foot and rocker arm, rotate the adjusting screw and pull the feeler gauge back and forth. When the feeler gauge has slight resistance, tighten the lock nut and check again. If the clearance changes, readjust it. There are two main methods to adjust the valve clearance:

1. Cylinder-by-cylinder adjustment method: The cylinder-by-cylinder adjustment method only needs to rotate each cylinder to the top dead center of the compression stroke of the cylinder (when the intake valve and exhaust valve are completely closed) to adjust the valve clearance of the cylinder. This method needs to find the top dead center of the compression stroke of each cylinder and remember the power sequence of various types of engines (gasoline engine is the ignition sequence and diesel engine is the fuel injection sequence).

2. Twice adjustment method: Twice adjustment method is to adjust all valves on the engine twice. The method is simple in operation and high in working efficiency. No matter how many cylinders there are, you only need to adjust them twice to complete the adjustment of all departments.
