(7) Hand tighten centering nut until all play in the
tool has been removed.
(8) Install dial indicator into locating block Tool
6549-1. Then screw extension rod onto dial indicator
(Fig. 193).
NOTE: The dial indicator used to make this mea-
surement must have a face that shows 0-50-0 (Spe-
cial Tool C-3339) readings (Fig. 194). All steps from
this point forward will reflect this assumption. This
will give you proper shim thickness.
(9) Before making a pinion depth measurement
the dial indicator must be zeroed. This is done by
placing the dial indicator in the zeroing fixture (spe-
cial tool 6549-6). Then place the zeroing fixture on a
flat surface. Adjust the dial face so the pointer on the
dial indicator lines up with the zero (Fig. 195).
(10) Compress the dial indicator slightly and
insert dial indicator pin into centering block (Fig.
196).
