    Reading B  
    Add reading A to reading B for a total end clearance  
    Divide the total reading by 2 for an average end clearance  
  18. NOTE: If the final measurement is not within specification, install a new snap ring until the correct specification is achieved.
    • 0.5-0.9 mm (0.019-0.035 in)

    If the free pack end clearance between the bottom of the snap ring and the top of the pressure plate is high, remeasure using a thicker select fit snap ring. If the free pack end clearance between the bottom of the snap ring and the top of the pressure plate is low, remeasure using a thinner select fit snap ring.
