How to install the timing chain of Mazda Six

2021-10-12

 
The installation method is as follows:

1. First locate the crankshaft at the compression top dead center of a cylinder, and there is a bolt in front of the left side of the engine block. Remove it and install a longer bolt. When the crankshaft runs to the top dead center of a cylinder, the bolt is pressed against the crank, so that the crankshaft is topped when it runs clockwise.
2. Then fix the incoming and outgoing camshafts, there is a gap at the back end of the camshaft, and the gap is eccentric. Rotate the camshaft until the gap is aligned with the sealing plane of the cylinder head, and find an open-end wrench of the same thickness and put it in the gap.
3. Install the timing chain on the timing gear, and install it in the direction of rotation when it is removed. Loosen the fixing bolts of the exhaust cam timing teeth to allow free rotation between the exhaust cam timing teeth and the camshaft. Install the chain guide plate and chain tensioner, and then loosen the locked timing chain tensioner.
4. There is a screw hole on the timing cover, use a suitable bolt (M6X1.0) to fix the crankshaft belt pulley on the timing cover. At this time, lock the crankshaft belt pulley bolts.
