Camshaft Gear

The first step for Camshaft gear replacement is to disconnect the negative battery cable followed by Timing Belt removal and bolted-on engine cover and Timing Belt. You must first disconnect the ignition wires attached to spark plugs as well as disconnecting crankcase ventilation tubes from valve cover and the Camshaft position (CMP) sensor. Use a screwdriver to unscrew the valve cover nuts followed by washers while removing the valve cover together with the Valve Cover Gasket with great caution to protect the Camshaft lobes and bearing surfaces from damage. Secure the intake Camshaft and then unscrew both the intake Camshaft gear bolt followed by the intake Camshaft gear. You should duplicate the procedure on the exhaust Camshaft by maintaining it in position then removing the exhaust Camshaft gear bolt and finally working on the exhaust Camshaft gear. The installation of the intake Camshaft gear can begin by securing it with the intake Camshaft gear bolt followed by a torque setting to 67.5 n.m (49 lb ft). Place the exhaust Camshaft gear in position before securing it with the exhaust Camshaft gear bolt that requires tightening to 67.5 n.m (49 lb ft). After these steps the technician should replace the engine cover then reconnect the crankcase ventilation tubes to the valve cover and reinstall the Timing Belt. The final step involves reattachment of the ignition wires to the spark plugs and negative battery cable.

Reconnect the crankcase ventilation tubes to the valve cover and the ignition wires to the spark plugs.
