I’ve noticed the crankshaft pulley on some Mazda engines don’t have keys. What is the proper installation procedure?
The AERA Technical Committee offers the following information regarding crankshaft pulley replacement for 2001-2005 Mazda 2.0L and 2.3L engines. The crankshaft pulley is not keyed to the crankshaft on these engines.
If the crankshaft pulley bolt is loosened, the pulley may move its position on the crankshaft. The engine must be re-timed whenever the crankshaft pulley bolt is loosened, removed or replaced. Several service tools are required to correctly re-time all the components.
Follow the procedure listed below to time the cams and crankshaft and tighten the new crankshaft bolt (p/n LF0111406).
Install the camshaft alignment plate (p/n 303-465) to the camshaft as shown in Figure 1.
Install the M6 x 1.0 bolt by hand as shown.
Rotate the crankshaft clockwise until the crankshaft is in the No.1 cylinder TDC position (until the crankshaft balance weight is contacting the crankshaft alignment pin (p/n 303-507).
Hold the crankshaft pulley using the service tools.
Tighten the crankshaft pulley lock bolt in the order shown following two steps using the service tool (p/n 49 D032 31 6).
* Tighten to 70.9 – 76.7 ft.lbs (96 – 104 Nm) (9.8 – 10.6 kgf-cm)
* Tighten 87°- 93°
Remove the M6 x 1.0 bolt.
Remove the service tool from the camshafts.
Remove the service tool from the cylinder block lower blind plug.
Rotate the crankshaft two times clockwise until the crankshaft is in the TDC position, reinstall the service tools to the camshaft and cylinder block, and inspect the valve timing.
If not aligned, loosen the crankshaft pulley lock bolt and repeat from Step 1.
