2. Remove front planetary gear (3) and front annulus
gear (2) as assembly.
3. Remove front planetary gear (1) and thrust washer
(2) from front annulus gear (3). Note thrust washer
position for assembly reference.
4. Remove tabbed thrust washer (2) from driving shell
(1). Note washer position for assembly reference.

5. Remove sun gear (3) and driving shell (2) as
assembly.
6. Remove tabbed thrust washer (2) from rear plane-
tary sun gear (1). Note washer position on gear for
assembly reference.
7. Remove rear planetary gear (3) and rear annulus
gear (2) from intermediate shaft (1).

8. Remove thrust washer (2) from rear planetary
annulus gear (1).
INSPECTION
Inspect the planetary gear sets and annulus gears. The planetary pinions,shafts, washers, and retaining pins are
serviceable. However, if a pinion carrier is damaged, the entire planetarygearsetmustbereplacedasanassembly.
Replace the annulus gears if the teeth are chipped, broken, or worn, or the gear is cracked. Replace the planetary
thrust plates and the tabbed thrust washers if cracked, scored or worn.
Inspect the machined surfaces of the intermediate shaft. Be sure the oil passages are open and clear. Replace the
shaft if scored, pitted, or damaged.
Inspect the sun gear and driving shell. If either component is worn or damaged, remove the sun gear rear retaining
ring and separate the sun gear and thrust plate from the driving shell. Thenreplace the necessary component.
Replace the sun gear as an assembly if the gear teeth are chipped or worn. Also replace the gear as an assembly
if the bushings are scored or worn. The sun gear bushings are not serviceable. Replace the thrust plate if worn, or
severely scored. Replace the driving shell if distorted, cracked, or damaged in any way.
Replace all snap-rings during geartrain assembly. Reusing snap-rings isnot recommended.
ASSEMBLY
1. Lubricate sun gear (2) and planetary gears with
transmission fluid during assembly. Use petroleum
jelly to lubricate intermediate shaft bushing sur-
faces, thrust washers and thrust plates (3) and to
hold these parts in place during assembly.
2. Install front snap-ring on sun gear (2) and install
gear in driving shell. Then install thrust plate (3)
over sun gear and against rear side of driving shell
(1). Install rear snap-ring (4) to secure sun gear
and thrust plate in driving shell. Note that the large
ID chamfer on the sun gear goes forward.

3. Install rear annulus gear (1) on intermediate shaft
(2).
4. Install thrust washer (2) to rear planetary annulus
gear (1) using petroleum jelly. Be sure washer is
seated against corner witht teh tabs completely in
the locating holes.
5. Install rear planetary gear (2) in rear annulus gear
(1). Be sure planetary carrier is seated against
annulus gear.
Page 3933 of 5267
6. Install tabbed thrust washer (2) on front face of
rear planetary gear (1). Seat washer tabs in match-
ing slots in face of gear carrier. Use extra petro-
leum jelly to hold washer in place if desired.
7. Lubricate sun gear bushings with petroleum jelly or
transmission fluid.
8. Install sun gear (5) and driving shell (2) on interme-
diate shaft (1). Seat shell against rear planetary
gear. Verify that thrust washer on planetary gear
was not displaced during installation.
9. Install tabbed thrust washer (3) in driving shell (2),
be sure washer tabs are seated in tab slots of driv-
ing shell. Use extra petroleum jelly to hold washer
in place if desired.

10. Install tabbed thrust washer (1) on front planetary
gear (2). Seat washer tabs in matching slots in
face of gear carrier. Use extra petroleum jelly to
hold washer in place if desired.
11. Install the torlon bushing onto the front planetary
carrier hub.
12. Install front annulus gear (1) over and onto front
planetary gear (2). Be sure gears are fully
meshed and seated.
Page 3935 of 5267
13. Install front planetary and annulus gear assembly
(2). 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.
14. Place geartrain in upright position. Rotate gears to
be sure all components are seated and properly
assembled. Snap-ring groove at forward end of
intermediate shaft will be completely exposed
when components are assembled correctly.
15. Install new planetary snap-ring (2) in groove at
end of intermediate shaft.
Page 3936 of 5267
16. Turn planetary geartrain over. Position wood block
under front end of intermediate shaft and support
geartrain on shaft. Be sure all geartrain parts
have moved forward against planetary snap-ring.
This is important for accurate end play check.
17. Check planetary geartrain end play with feeler
gauge (3). Insert gauge between rear annulus
gear (2) and shoulder on intermediate shaft (1) as
shown. End play should be 0.15 to 1.22 mm
(0.006 to 0.048 in.).
18. If end play is incorrect, install thinner/thicker plan-
etary snap-ring as needed.
