Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Standard Idler Gear
Clean all of the components and inspect all of the components that were removed in the previous procedure. If necessary, replace any worn component and/or any damaged component. Note: Timing pins are used in order to time the engine at top dead center. The timing pins are a slip fit. Do not use excessive force to install the timing pins. Do not use the timing pins to lock the engine during repairs.
Ensure that the No. 1 cylinder is still at the top center position on the compression stroke. If necessary, refer to the Testing and Adjusting Manual, "Finding Top Center Position for No. 1 Piston". Ensure that the timing pin for the crankshaft is installed and that the timing pin for the camshaft is installed. Note: Ensure that the marks on the idler gear (1) face toward the front.
