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.
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).
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.
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.
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.
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.
