    1 - TOOL 8266 -17
    2 - TOOL C-3339A
  8. Using Adapter (Special Tool No. 8266-17, Spline Tool, RFE Output) from End-Play Tool Set (Special Tool No. 8266B, End Play Socket Set) (1) and Dial Indicator (Special Tool No. C-3339A, Set, Dial Indicator) (2), measure and record the input shaft end-play.
    NOTE:

    When measuring the input shaft end-play, two "stops" will be felt. When the input shaft is pushed inward and the dial indicator zeroed, the first "stop" felt when the input shaft is pulled outward is the movement of the input shaft in the input clutch housing hub. This value should not be included in the end-play measured value and therefore must be recorded and subtracted from the dial indicator reading.
