Drain the cooling system and remove the water pump. If applicable, remove the power steering pump. Take off the fuel lines and fuel pump. Remove the pulley from the vibration damper, along with the bolt and washer attaching the damper to the
Crankshaft, while locking the crankshaft by holding the
Flywheel with a suitable tool; a large breaker bar or impact wrench will be necessary for the crankshaft bolt removal. Use a puller to detach the damper. For 318/360 engines, loosen the
Oil Pan bolts and remove the pan bolt on each side. Take off the timing cover bolts and remove the cover, being careful not to damage the oil pan gasket at the front on 318/360 models. Measure the chain stretch, then remove the
Camshaft bolt, and for 316/380 engines, also take off the cup washer and fuel pump eccentric. Remove the chain along with the camshaft and crankshaft sprockets. Install the crankshaft timing gear and the shaft key, followed by the timing chain assembly and the fuel pump eccentric cam. Ensure the timing marks are aligned on the inside edges of the timing gears before tightening the camshaft gear bolt to the specified torque. Apply assembly lubricant to the outside diameter of the fuel pump eccentric cam, then install a new crankshaft front seal in the timing chain cover. Use ATV-type sealant to hold the timing chain cover gasket in place, install the timing chain cover, and tighten the mounting bolts to the specified torque. Lubricate the seal contact surface of the vibration damper, then use a sleeve and bolt type installation tool to install the vibration damper; if unavailable, a large wooden block and hammer can be used as a substitute. Lock the crankshaft and install the damper mounting bolt, tightening it to the specified torque. Finally, install the power steering pump if applicable, the water pump, and refill the cooling system.
