t a n c e o f 0.38 m m ( 0 . 0 1 5 i n ) w i t h t h e s p r e a d e r
t o o l . Measure the separation distance w i t h the d i a l
indicator (Fig. 4) as the housing is being separated.
(11) Remove the d i a l indicator (Fig. 4) when the
differential housing has been separated
sufficiently
to remove t h e differential case from the housing.
(12) Pry the differential case loose f r o m the hous-
ing. A l i g h t p r y i n g action w i t h a s m a l l p r y bar or
pinch bar w i l l loosen the case sufficiently for easy re-
moval. To prevent damage, p r y the differential case
outward t o w a r d the opening w i t h the p r y bar pivot-
i n g on the differential housing and w i t h the end of
the pry bar against the differential case.
(13) Remove the differential case from the differen-
t i a l housing. I f t h e y are reusable, r e t a i n the differen-
t i a l bearing cups and bearings together as "matched
sets".
(14) C l a m p the differential case i n a vise equipped
w i t h soft j a w s and remove ( a n d d i s c a r d ) the r i n g
gear bolts. Use a punch to loosen and remove the
r i n g gear f r o m the differential case flange (Fig. 5).
Remove the r i n g gear. T h e r i n g g e a r c a n be re-

(15) The excitor r i n g e r can be removed w i t h a soft-
faced h a m m e r (Fig. 6). Discard after removal.
(16) I n s t a l l the differential case ( w i t h the original
bearing cups) i n t h e differential housing.
(17) Remove the holddown clamps and the spreader
tool from the differential housing (Fig. 4).
