Illustration 1 g01471253
(1) Timing marks for the camshaft gear (2) Timing marks for the idler gear (3) Timing marks for the fuel injection pump gear (4) Timing marks for the crankshaft gearNote: When the timing gear case is not installed, do not turn the crankshaft gear.
Ensure that the No. 1 piston is at top center on the intake stroke. Refer to Illustration 1.
Make sure that the marks on the gears are in alignment.Note: The idler gear has an odd number of teeth. The exact position in Illustration 1 may never be obtained. When the No. 1 piston is at top center on the intake stroke, each of the other gears will have two numbers that are straddling a tooth on the idler gear.
Install a dial indicator and rotate the idler gear in order to measure backlash.
Measure the backlash between the crankshaft gear and the idler gear. The backlash between the crankshaft gear and the idler gear should be between0.03 mm (0.0012 inch) to 0.17 mm (0.0067 inch).If the backlash is greater than the maximum allowable backlash of 0.25 mm (0.010 inch), replace the gears and measure the backlash again.
