How to align the timing chain of BYD?

[MacMiguel]

For the BYD timing chain, the camshaft needs to be rotated to the top dead center of the first cylinder's compression stroke, and the locating pin of the crankshaft pulley should be vertically upward. Then, install the chain. The main function of the timing chain is to drive the engine's valve train, ensuring that the intake and exhaust valves open or close at the appropriate time to allow normal air intake and exhaust in the engine cylinders. BYD is a Chinese automotive brand primarily producing commercial and household sedans, as well as batteries. Its product lineup includes models like the BYD Yuan, Song MAX, BYD F3, and Surui. Taking the BYD F3 as an example, it is an A+ class passenger car equipped with features such as an LED self-illuminating instrument cluster, anti-submarine seats with 10-way manual adjustment, HUD speed display, full Chinese eight-direction display, and manual air conditioning.
