Timing Drive Components: Removal

WARNING: This page is about a different variant/trim than selected.

NOTE: Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if the pulley bolt is loosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage can occur.

NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.

With the vehicle in NEUTRAL, position it on a hoist. REFER to JACKING AND LIFTING for lifting points.
Remove the fuel injection pump and tappet. REFER to FUEL INJECTION PUMP .
Remove the RH fender splash shield. REFER to FENDER SPLASH SHIELD .
Using the crankshaft pulley bolt, rotate the engine clockwise until the fuel injection cam lobe is at zero lift.
