Pilot Runout

PILOT RUNOUT

1. Position the Dial Indicator with Bracketry with the Clutch Housing Alignment Adapter 308-021 (T75L4201-A) or equivalent to the pilot, as close to the hub or axle flange face as possible. Zero the indicator to allow the pointer to deflect either way.
2. Rotate the hub or flange one full turn and note the maximum and minimum readings. The difference between the maximum and minimum readings will be the total pilot runout. Pilot runout must not exceed 0.15 mm (0.006 inch).
