Transmission Case Assembly
(1) Coat countershaft thrust washers with petro-
leum jelly and install washers in case. Index tab on
large, bronze-faced washer in locating recess in front of
case. Index notch in smaller, steel washer with locating
lug at rear of case.
(2) Install countershaft gear assembly.
(3) Install remaining countershaft thrust washer
between rear of countershaft gear and smaller, steel
thrust washer.
(4) Install countershaft from rear of case but do not
install shaft completely. Stop installation when shaft
just starts into case front bore.
CAUTION: When installing the countershaft, keep the
shaft and arbor tool in constant contact to avoid dis-
placing any bearing rollers or bearing washers.
(5) Install reverse idler gear. Larger gear end must
face rear of case.

Tap shaft forward until lock plate slot in shaft is aligned
with lock plate slot in countershaft.

idler gear shaft slots.
(8) Tap ends of countershaft and reverse idler gear
shafts alternately until shafts are fully installed.

blocking ring in case front bearing bore. Insert shaft
from case interior, not from front or outside of case.
(10) Install mainshaft and gear train assembly.
(11) Install mainshaft pilot bearing roller spacer on
mainshaft pilot hub if not installed previously.
(12) Insert mainshaft pilot hub in clutch shaft bore.

drive bearing onto mainshaft and into case rear bore.
Seat snap ring against case.

the seal lip will face the transfer case (fig. 2B-43).

jelly.
(17) Position replacement transmission-to-adapter
gasket on transmission and install adapter plate. Apply

ing retaining washer on clutch shaft with dished side of
washer facing mainshaft.
