CHECK IDLER LOW GEAR RADIAL AND THRUST CLEARANCE
1. Using a feeler gauge, measure the idler low gear thrust clearance.
  Standard clearance: 0.125 to 0.275 mm (0.0049 to 0.0108 in.)
  
  Maximum clearance: 0.275 mm (0.0108 in.)
  
  If the clearance is greater than the maximum, replace the idler low gear, needle roller bearing or idler gear.
