PLANETARY GEARTRAIN/OUTPUT SHAFT

DISASSEMBLY

(1) Remove planetary snap ring from intermediate

shaft (Fig. 227). Discard snap ring as it is not reus-
able.

(2) Remove front planetary gear and front annulus

gear as assembly (Fig. 228).

(3) Remove

front

planetary

gear

and

thrust

washer from front annulus gear (Fig. 229). Note
thrust washer position for assembly reference.

(4) Remove tabbed thrust washer from driving

shell (Fig. 230). Note washer position for assembly
reference.

(5) Remove sun gear and driving shell as assembly

(Fig. 231).

(6) Remove tabbed thrust washer from rear plane-

tary gear (Fig. 232). Note washer position on gear for
assembly reference.

(7) Remove rear planetary gear and rear annulus

gear from intermediate shaft (Fig. 233).

(8) Remove thrust plate from rear annulus gear

(Fig. 234).

ASSEMBLY

(1) Lubricate sun gear and planetary gears with

transmission fluid during assembly. Use petroleum
jelly to lubricate intermediate shaft bushing surfaces,
thrust washers and thrust plates and to hold these
parts in place during assembly.

(2) Install front snap ring on sun gear and install

gear in driving shell. Then install thrust plate over
sun gear and against rear side of driving shell (Fig.
235). Install rear snap ring to secure sun gear and
thrust plate in driving shell.

(3) Install rear annulus gear on intermediate shaft

(Fig. 236).

(4) Install thrust plate in annulus gear (Fig. 237).

Be sure plate is seated on shaft splines and against
gear.

(5) Install rear planetary gear in rear annulus

gear (Fig. 238). Be sure planetary carrier is seated
against annulus gear.

(6) Install tabbed thrust washer on front face of

rear planetary gear (Fig. 239). Seat washer tabs in
matching slots in face of gear carrier. Use extra
petroleum jelly to hold washer in place if desired.

(7) Lubricate sun gear bushings with petroleum

jelly or transmission fluid.

DISASSEMBLY AND ASSEMBLY (Continued)

(8) Install sun gear and driving shell on interme-

diate shaft (Fig. 240). Seat shell against rear plane-
tary gear. Verify that thrust washer on planetary
gear was not displaced during installation.

(9) Install tabbed thrust washer in driving shell

(Fig. 241), be sure washer tabs are seated in tab slots

of driving shell. Use extra petroleum jelly to hold
washer in place if desired.

(10) Install tabbed thrust washer on front plane-

tary gear (Fig. 242). Seat washer tabs in matching
slots in face of gear carrier. Use extra petroleum jelly
to hold washer in place if desired.

(11) Install front annulus gear over and onto front

planetary gear (Fig. 243). Be sure gears are fully
meshed and seated.

(12) Install front planetary and annulus gear

assembly (Fig. 244). Hold gears together and slide
them onto shaft. Be sure planetary pinions are
seated on sun gear and that planetary carrier is
seated on intermediate shaft.

(13) Place geartrain in upright position. Rotate

gears to be sure all components are seated and prop-
erly assembled. Snap ring groove at forward end of
intermediate shaft will be completely exposed when
components are assembled correctly.

(14) Install new planetary snap ring in groove at

end of intermediate shaft (Fig. 245).

(15) Turn planetary geartrain over. Position wood

block under front end of intermediate shaft and sup-
port geartrain on shaft. Be sure all geartrain parts
have moved forward against planetary snap ring.
This is important for accurate end play check.

(16) Check planetary geartrain end play with

feeler gauge (Fig. 246). Insert gauge between rear
annulus gear and shoulder on intermediate shaft as
