Section 4: Assembly
5.4Measuring bearing clearance on input shaft
a) Turn input shaft several times to permit bearings to
seat.
b) Fit clamping ring to the spline of the input shaft.
c) "0" dial indicator to obtain accurate reading.
d) With two levers carefully pry on the clamping ring and
record end play of shaft.
This step must be done very carefully to obtain the ac-
tual bearing clearance.
NOTE
e) Carry out steps "a" and "d" for several times
f) The bearing clearance measured plus the pretension
required in section 5.1 will determine the required
thickness of shims.
Round off the determined shims thickness to 0.05 mm
(0.001968 in.).
5.5 Measuring bearing clearance at
intermediate and reversal shafts
a) Unscrew plug (item 1, Fig. 5-5a) from the housing
b) Screw bolt (tool no. 458105) (item 2, Fig. 5-5a) into in-
termediate shaft
c) Mount dial gauge support securely onto housing
d) Turn intermediate shaft several times to permit bear-
ings to seat
e) Adjust the dial indicator needle on top of the bolt
head, and "0" indicator (Fig. 5-5b)
f) Screw hexagon nut carefully against housing flange
until bearing 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" for several times
h) The bearing clearance measured plus the pretension
required in section 5.1 will determine the required
thickness of shims.
NOTE
Round off the determined shimr thickness to 0.05 mm
(0.001968 in.)
i) Unscrew bolt with nut and remove dial gauge with
support.
l) Repeat same procedure for reversal shaft.
