(4) Tap input gear out of bearing with plastic mal-
let (Fig. 31).
(5) Remove input gear and planetary/PTO gear as
assembly (Fig. 32).
INPUT AND PLANETARY GEAR
The only removable parts in the planetary assem-
bly are the snap-rings, needle bearing, thrust wash-
ers, lock ring, input gear, and support sleeve.The
planetary carrier, PTO gear, planetary pinions,and remaining planetary components are fixed
parts and are serviced as an assembly.
(1) Position planetary assembly so PTO gear is on
bench (Fig. 33).
(2) Remove retaining ring that secures input gear
and lock ring in planetary assembly.
(3) Remove lock ring and front thrust washer from
carrier (Fig. 34). Note that lock ring and thrust
washer are both tabbed.
(4) Remove input gear from planetary carrier (Fig.
35). Lift gear straight up and out of carrier.
(5) Remove support sleeve from carrier (Fig. 36).
(6) Remove rear thrust washer (Fig. 37).
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
If any pump component is worn, or damaged, the
pump must be replaced as an assembly.

Inspect the spline teeth on the synchronizer hub
(Fig. 38). 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.
Inspect all gear teeth and splines for wear or dam-
age. Also check splines for burrs, or nicks. Removeminor nicks and scratches with an oil stone. Replace
any part with damaged splines.
It is recommended that all retaining rings be
replaced during overhaul. Most of the retaining rings
can be distorted during removal and should not be
reused.
Inspect the two case halves, for cracks, porosity,
damaged mating surfaces, stripped bolt threads, or
distortion. Replace either case half if necessary. How-
ever, stripped threads can be repaired with Heli-
CoilŸ stainless steel thread inserts. The case vent
tube can be resecured with LoctiteŸ 680 if necessary.
Inspect the annulus gear. Be sure the gear teeth
are in good condition. Replace the front case and
annulus as an assembly if the gear is damaged.
