DRIVE PINION GEAR DEPTH MEASUREMENT
AND ADJUSTMENT WITH TOOL SET D-271
The following drive p i n i o n gear depth (i.e., t h e
depth of the gear teeth mesh between t h e d r i v e p i n -
ion gear and t h e r i n g gear) measurement a n d adjust-
m e n t procedure involves u s i n g Tool Set D-271 (Fig.
34).
(1) Insert Master P i n i o n Block Tool D-120 i n t o t h e
drive p i n i o n gear shaft bore i n t h e differential hous-
i n g (Fig. 35).
(2) Place A r b o r Disc Tools D-116-2 o n A r b o r Tool
D-115-3 and position t h e tool set i n t h e differential
housing w i t h t h e disc tools located i n t h e differential
b e a r i n g cradles (Fig. 36). This is the centerline o f the
r i n g gear/axle shaft.
(3) Place P i n i o n H e i g h t Block Tool D-116-1 o n top
of t h e master p i n i o n block tool and against t h e arbor
tool (Fig. 37).
(4) Place Gauge Block Tool D-115-2 a n d D i a l I n d i -
cator Tool D-106-5 on t h e l o w e s t step o f t h e p i n i o n
h e i g h t block tool ( F i g . 38). Ensure t h a t t h e gauge
block tool is r e s t i n g f i r m l y o n t h e lowest step o f p i n -
