INSPECT RUNOUT OF INTERMEDIATE SHAFT AND
PROPELLER SHAFT

Maximum runout:

0.8 mm (0.031 in.)

If the runout is greater than the maximum, replace the propel-
ler shaft assembly.

4.

INSPECT SPIDER BEARING

•

Check if the spider bearing rotates smoothly.

•

Check if there is any play in the spider bearing.

If necessary, replace the propeller shaft assembly.

INSTALL FLANGE ON INTERMEDIATE SHAFT

(a) Coat the spline of the intermediate with MP grease.
(b) Place the flange on the shaft and align the matchmarks.

HINT: If replacing either the center flange or intermediate
shaft, reassemble them so that the front yoke of the inter-
mediate shaft and the rear yoke of the propeller shaft are fac-
ing in the same direction.

(c) Using SST to hold the flange, press the bearing into position

by tightening down a new nut.
