gear (1).
5. Apply a load in one direction and oscillate the shaft
several times while the load is applied.
Set the dial gauge to zero.
Apply the load in the opposite direction, oscillate and
read the axial movement of the shaft.
Make three measurements at 120 ° of the intermedi-
ate shaft. Calculate the arithmetic mean of the three
readings, it should be 0-0.03 mm (0-0.001 in).
If required, adjust the shims. To decrease the axial
movement, decrease the quantity of shims.
IMPORTANT: Be sure to measure on gear (1) as the other
gears are mounted on needle bearings.
