Place the contact tip of the gauge against the face of the idler gear. Idler Gear End Clearance mm in 0.30 MIN 0.012 0.53 MAX 0.021 Use the dial indicator gauge with the magnetic base to measure the idler gear backlash. Place the contact tip of the gauge against a tooth on the idler gear.
Do not allow the mating gears to move while measuring the backlash. Idler Gear Backlash mm in 0.08 MIN 0.003 0.41 MAX 0.016 Use the dial indicator gauge to measure the accessory drive gear backlash. Place the contact tip of the gauge against a tooth of the accessory drive gear. Do not allow the mating gear to rotate while measuring the backlash.
