4.5.4 Measuring bearing clearance on input
shaft
a) Turn input shaft severaltimes to permit bearings to
seat.
b) Fit clamping ring (tool p/n 219.354.3 (618582)) to the
spline of the input shaft (item 1, Fig. 5-4).
c) Adjust to «O», dialindicator to obtain accurate reading.
d) With two levers carefully pry on the clamping ring
and record end play of shaft.
NOTE
This step must be done very carefully to obtain the
actual bearing clearance.
e) Carry out steps, a) and d) severaltimes.
f) The bearing clearance measured plus the pretension
required in section 5.1 determine the required thick-
ness of shims.
4.5.5 Measuring bearing clearance at
intermediate shaft
a) Unscrew plug (item 1, Fig. 5-5a) from the housing.
b) Screw in specialtool(p/n 224.836.008 (458105))
(item 2, Fig. 5-5a) into intermediate shaft hole.
c) Mount dialgauge support securely onto housing.
d) Turn intermediate shaft severaltimes to permit bear-
ings to seat.
e) Adjust the dial indicator needle on top of the bolt
head and «O» to dialindicator (Fig. 5-5b).
f) Screw hexagon nut carefully against housing (inter-
mediate shaft moves up) untilbearing clearance is
overcome (Fig. 5-5b).
NOTE
This step should be done very carefully to obtain the
actual bearing clearance.
g) Carry out steps d) and f) severaltimes.
h) The clearance measured plus the pretension re-
quired in section 5.1 determine the required thick-
ness of shims.
4.5.6 Measuring the bearing clearance on
the output shaft
a) Insert output flange onto the output shaft and screw
in nut ring.
b) Install bolt and spacer on input shaft.
c) Turn output shaft repeatedly to permit bearings to seat.
d) Mount dialgauge support securely onto housing.
e) Place dial gauge onto top of the output shaft and ad-
just it to «0» reading.
f) Lift output shaft carefully, using two screwdrivers,
and record measurement (Fig. 5-6).
NOTE
This step should be done very carefully to obtain the
actual bearing clearance.
g) Carry out steps c) and f) for severaltimes.
h) The bearing clearance measured plus the preten-
sion required in section 5.1 will determine the re-
quired thickness of shims.
