PLANETARY GEARTRAIN/OUTPUT SHAFT

DISASSEMBLY

(1) Remove planetary snap ring (Fig. 222).
(2) Remove front annulus and planetary assembly

from driving shell (Fig. 222).

(3) Remove snap ring that retains front planetary

gear in annulus gear (Fig. 223).

(4) Remove tabbed thrust washer and tabbed

thrust plate from hub of front annulus (Fig. 224).

(5) Separate front annulus and planetary gears

(Fig. 224).

(6) Remove

front

planetary

gear

front

thrust

washer from annulus gear hub.

(7) Separate and remove driving shell, rear plane-

tary and rear annulus from output shaft (Fig. 225).

(8) Remove front planetary rear thrust washer

from driving shell.

(9) Remove tabbed thrust washers from rear plan-

etary gear.

(10) Remove lock ring that retains sun gear in

driving shell. Then remove sun gear, spacer and
thrust plates.

ASSEMBLY

(1) Lubricate output shaft and planetary compo-

nents with transmission fluid. Use petroleum jelly to
lubricate and hold thrust washers and plates in posi-
tion.

(2) Assemble rear annulus gear and support if dis-

assembled. Be sure support snap ring is seated and
that shoulder-side of support faces rearward (Fig.
226).

DISASSEMBLY AND ASSEMBLY (Continued)

(3) Install rear thrust washer on rear planetary

gear. Use enough petroleum jelly to hold washer in
place. Also be sure all four washer tabs are properly
engaged in gear slots.

(4) Install rear annulus over and onto rear plane-

tary gear (Fig. 226).

(5) Install assembled rear planetary and annulus

gear on output shaft (Fig. 227). Verify that assembly
is fully seated on shaft.

(6) Install front thrust washer on rear planetary

gear (Fig. 228). Use enough petroleum jelly to hold
washer on gear. Be sure all four washer tabs are
seated in slots.

(7) Install spacer on sun gear (Fig. 229).
(8) Install thrust plate on sun gear (Fig. 230). Note

that driving shell thrust plates are interchangeable.
Use either plate on sun gear and at front/rear of
shell.

(9) Hold sun gear in place and install thrust plate

over sun gear at rear of driving shell (Fig. 231).

(10) Position wood block on bench and support sun

gear on block (Fig. 232). This makes it easier to align
and install sun gear lock ring. Keep wood block
handy as it will also be used for geartrain end play
check.
