Check nominal dimension "
X
" as marked on the pinion. Add up to
or subtract from "
X
" the variation indicated as "
Y
" to obtain the
actual centre distance "
I".
EXAMPLE: I = 153 - 0.2 = 152.8
Calculate shims "
S
" for insertion under the thrust block of the inner
bearing using the following formula:
S
= 196 - (I + D) where: 196 = fixed dimension
I
= actual pinion centre distance
D
= Total bearing thickness;
EXAMPLE:
S
= 196 - (152.8 + 42.38) = 0.82 mm.
Subtract 0.05±0.07 mm from the resulting
S
value, until the value is
rounded off to the lower 5/100.
EXAMPLE:
S
= 0.82
R
0.75 mm.
Make up the pack of shims "
S
".
Mount driver
T20A
, thrust block of inner bearing (10) and pack of
shims (11) onto tension bar
T20B
Introduce the tension bar into the
main body and mount the thrust block of outer bearing (9) and
driver
T20C
.
NOTE.
Grease shims to hold them in position.
Connect the tension bar to the press and push the thrust blocks of
bearings (9) and (10) into their seats.
Disconnect from the press and remove tension bar and drivers.
CALCULATING PINION BEARINGS ROLLING TORQUE
Introduce tool
T17
complete with bearings (9) and (10) into the
main body (6); tighten by hand until a rolling torque is definitely
obtained.
