INSPECTION
NOTICE:
Be careful not to grip the propeller shaft tube too tightly in
a vise as this will cause deformation.
1. INSPECT PROPELLER SHAFT AND INTERMEDIATE
SHAFT FOR DAMAGE OR RUNOUT
Using a dial indicator, check the runout of each shaft.
Maximum runout: 0.8 mm (0.031 in.)
If shaft runout is greater than the maximum, replace the shaft.
2. INSPECT SPIDER BEARING
(a) Inspect the spider bearing for wear or damage.
(b) Using a dial indicator, check the spider bearing axial play
by turning the yoke of flange while holding the shaft tight-
ly.
Maximum bearing axial play: 0.05 mm (0.0020 in.)
If the spider bearing axial play exceeds the maximum, replace
the spider bearing (See page PR±10).
