Example Embodiment
[0012] The assembly method is to fix the crankshaft and camshaft, assemble the crankshaft, camshaft timing gear, tensioner and idler, install the timing belt, and finally tighten the camshaft timing gear bolts, and then tighten the camshaft timing gear During the bolting process, ensure that the timing gear and camshaft have no relative rotation.
[0013] As shown in the figure, the non-relative rotation of the timing gear and the camshaft is achieved by the following method: the camshaft timing gear has an extra hexagonal flange surface 1. When tightening the camshaft timing gear bolts, use the timing tool to pass The hexagonal flange of the timing gear fixes it to ensure that the camshaft timing gear and the camshaft do not rotate relative to each other during the process of tightening the camshaft timing gear bolt, thereby reducing the timing error.
