PROPELLER SHAFT 4A-15

Propeller Shaft Run-Out


401R300005




Support 1 of splined yoke, 2 of center bearing and 3 of flange
yoke and check for static run-out by holding the probe of a dial
indicator in contact with the center part of the shaft and turning
the propeller shaft.
If the amount of run-out is beyond the limit value, correct with a
bench press or replace the shaft with a new one.

Play in Spider Bearing
(1) Check the spider bearings for wear or damage.
(2) Check the amount of axial and radial play in spider bearing
by moving the yoke back and forth on the spider axes and
shaft axis.

Universal Joint Reassembly
1. Set the propeller shafts.

Be sure to set the propeller shaft yoke by aligning the
setting marks made during dissassembly.
2. Spider
 Be sure to install the spider by aligning the setting marks
made during disassembly.
3. Needle Roller Bearing
1) Apply a molybdenum-disulfide grease or a multi-purpose.
type grease NLGI No.2 to inside of the bearing cap.
Grease Amount g(oz)
Approx. 1.2 (0.042)

2) Using either a mallet (or copper hammer) or a press, install
the needle roller bearing into the yoke so that snap ring can
be installed in its groove.

CAUTION:

  The needle roller bearing cannot be installed smoothly
if it is set at an incorrect angle with the flange.

  Excessive hammering will damage the needle rolle
r
bearing.

3) Align setting marks and join the yokes.
NOTE:
Assemble the spider and spline yoke so that their grease
fittings are arranged on the same side.(4

4. Snap ring
NOTE:
Discard used snap rings and install new ones.

When the bearing cap is in position, select and attach a snap
ring of suitable thickness so that the end play of the spider pin
is held within 0.1mm (0.004in).
