Gear Shift Shafts
Check the part of shaft as indicated in below
figure for uneven wear. Replace shaft if uneven
wear is noted.
Fig. 13-40
Extension Case Bush
Check bush press-fitted in extension case for
wear by measuring radial clearance between
bush bore and sliding yoke. If sliding yoke
rattles in bush because of advanced wear it will
cause propeller shaft to rattle. For this reason,
an extension case found to allow its sliding
yoke to rattle in excess of service limit must be
replaced; replacement of bush alone is not
permissible.
