NOTE:
- The adapter plate will be the base point for the measurement. Use a scraper to remove any gasket material remaining on the end face.
- During measurement, do not place the height gauge in the shaded area shown in the figure.

NOTE:
- Set the height gauge indicator near the measurement target, and lock dial (1) as shown in the figure. Turn dial (2), and set the indicator to the end face of the reverse coupling sleeve side.
- Turn approximately 72° at a time, and measure the coupling sleeve in 5 locations. Round down the 2 highest and 2 lowest measurement values. The remaining center value is used as the measurement value.

Calculate the neutral position of the reverse coupling sleeve according to the measurement. From the following calculation, select a fork rod which matches the calculated value.

Calculation: T + 4.8 mm (0.189 in)

T + 4.8 mm (0.189 in) mm (in)	Lot No. (marking)
33.50 - 33.80 (1.3189 - 1.3307)	32816AA190 (1)
33.80 - 34.10 (1.3307 - 1.3425)	32816AA200 (none)
34.10 - 34.40 (1.3425 - 1.3543)	32816AA210 (2)
T = Thickness
