Calculate the average of the readings.

Calculation of the value of the timing washer

Value of the pre-setting washer + average of the

readings on the dial gauge - 0.02 (value to subtract to

guarantee a minimum clearance) = value of the timing

washer.

Example: (Values in mm).

NOTE: a set of timing washers of 0.86 mm to 1.30 mm

from 0.04 mm to 0.04 mm thickness is supplied as

replacement parts.
