1. INSPECT IDLER GEAR
Using a micrometer, measure the idler gear diameter.
Standard diameter: 38.48 - 38.50 mm (1.5149 - 1.5157 in.) Maximum diameter: 38.50 mm (1.5157 in.)
2. INSPECT IDLER LOW GEAR
Using a cylinder gauge, measure the idler low gear diameter.
Standard diameter: 45.52 - 45.54 mm (1.7922 - 1.7930 in.) Maximum diameter: 45.54 mm (1.7930 in.)
