Mark the thrust block and the internal bearing (17) on a faceplate,
allow the bearing to set by rotating them in both directions and by
applying a vertical thrust. With a centesimal, digital depth gauge
"B", check overall thickness of bearing (e.g.: 42.35 mm) and set the
gauge to zero again.

GB
On the bar-hold of pinion (16), check the value "X" (in brackets)
relative to the deviation from the theoretical centre distance.
NOTE. "Y" is the number of pinion/crown coupling.

Using a driver, mount the sealing ring (22) in the reduction unit (11).
NOTES. 1 - Carefully check the direction of assembly.
2 - Lubricate the outer surface of the sealing ring.

Lay two 20 mm gauged blocks "C" on the face of the reduction gear
body (11). With depth gauge "B" (set to zero at the previous point),
measure space between the "C" blocks and the striking surface of
internal bearing (17). The size obtained (e.g.: 0.81 mm) is the
theoretical shim "St" (18) to be inserted under the thrust block of
bearing (17).

To calculate final thickness "S", add the negative value of "X" to
"St" or, alternatively, subtract the positive value of "X".
For ex.: Deviation X=(±0.13 mm): S=St+X=0.81+0.13=0.94 mm
Deviation X=(+0.12 mm): S=St ± X=0.81 ± 0.12=0.69 mm
CAUTION! Round off to as close to 0.05 mm as possible.

Place the reduction gear body (11) under a press and, using tool
T10, insert the thrust block of external bearing (21).
CAUTION! Insert the thrust block of the bearing that is not
countermarked.
