damage, corrosion or any other abnormal condition is
found through inspection.
NOTE: When any part of the journal assembly (spider,
needle roller bearing) requires replacement, be sure to
replace the entire assembly.
Check the following parts for wear, damage, noise or any
other abnormal conditions:
1. Spider
2. Needle roller bearing

Propeller Shaft Run–out
Support the ends of the propeller shaft on V-blocks (2)
and check for run–out by holding the probe of a dial
indicator (1) in contact with the center part of the shaft. If
the amount of run–out is beyond the standard value for
assembly, correct with a bench press or replace the shaft
with a new propeller shaft assembly.
Standard: 0.3 mm (0.012 in)
Limit: 0.5 mm (0.02 in)
