struts appear worn, remove struts and springs from
hub. Note position of springs for installation refer-
ence (Fig. 29).
(4) Remove brass stop ring (Fig. 30). Discard stop
ring if worn, cracked, or any teeth are missing.

(5) Place front case in horizontal position. Then
remove input gear and low range gear as an assem-
bly (Fig. 35). Tap gear out of bearing with plastic
mallet, if necessary.
INPUT AND PLANETARY GEAR
(1) Remove snap-ring that retains input gear in
low range gear (Fig. 36).
(2) Remove retainer (Fig. 37).
(3) Remove front tabbed thrust washer (Fig. 38).
(4) Remove input gear (Fig. 39).

CLEANING
Clean the transfer case parts with a standard
parts cleaning solvent. Remove all traces of sealer
from the cases and retainers with a scraper and
3MŸ all purpose cleaner. Use compressed air to
remove solvent residue from oil feed passages in the
case halves, retainers, gears, and shafts.

INSPECTION
MAINSHAFT/SPROCKET/HUB
Inspect the splines on the hub and shaft and the
teeth on the sprocket (Fig. 41). Minor nicks and
scratches can be smoothed with an oilstone, however,
replace any part that is damaged.
Check the contact surfaces in the sprocket bore
and on the mainshaft. Minor nicks and scratches can
be smoothed with 320-400 grit emery cloth but do not
try to salvage the shaft if nicks or wear is severe.
Inspect the spline teeth on the synchronizer hub. If
evidence of chipping or excessive wear is apparent,
replace the hub. The hooked end of each synchronizer
spring should be inserted in one of the struts. In
addition, the springs should not interfere with the
polished gear cone or inside diameters of the hub.
Inspect the stop ring for cracks and wear. Replace
the ring if necessary or if doubt exists over condition.
Check a replacement synchronizer ring for proper fit
on the cone with a minimum of wobble. Also check
the synchronizer struts for wear or damage.
INPUT GEAR AND PLANETARY CARRIER
Check the teeth on the gear (Fig. 42). Minor nicks
can be dressed off with an oilstone but replace the
gear if any teeth are broken, cracked, or chipped. The
bearing surface on the gear can be smoothed with
300-400 grit emery cloth if necessary.
Examine the carrier body and pinion gears for
wear or damage. The carrier will have to be replaced
as an assembly if the body, pinion pins, or pinion
gears are damaged.
Check the lock ring and both thrust washers for
wear or cracks. Replace them if necessary. Also
replace the lock retaining ring if bent, distorted, or
broken.
