(4) Remove front planetary gear.
(5) Remove front planetary rear thrust washer.
(6) Remove sun gear and driving shell.
(7) Remove snap ring that retains sun gear in driv­
ing shell and remove sun gear and thrust plates.
Note thrust plate position for assembly reference.
(8) Remove tabbed thrust washer from rear plane­
tary gear.
(9) Remove rear planetary gear from rear annulus
gear and remove annulus gear from intermediate shaft.
(10) Remove snap rings securing annulus gears to
supports. Then separate each gear from support.
PLANETARY GEARTRAIN INSPECTION
Clean the planetary components in solvent and dry
them with compressed air.
Check sun gear and driving shell condition. Re­
place the gear if damaged or if the bushings are
scored or worn. The bushings are not serviceable. Re­
place the driving shell if worn, cracked or damaged.
Replace planetary gear sets if gears, pinion pins, or
carrier are damaged in any way. Replace the annulus
gears and supports if either component is worn or dam­
aged.
Inspect the geartrain spacers, thrust plates, snap
rings, and thrust washers. Replace any part that is
worn or damaged. Do not attempt to reuse these parts.
Inspect the intermediate shaft carefully. Pay partic­
ular attention to the machined bushing/bearing sur­
faces on the shaft.
Replace the intermediate shaft if any machined
surfaces are scored, pitted, or damaged in any way.
Also replace the shaft if the splines are damaged, or
exhibits cracks at any location. Be sure the select
spacer groove on the shaft is in good condition. Trial
fit the spacer if necessary.
PLANETARY GEARTRAIN ASSEMBLY
(1) Lubricate intermediate shaft and planetary com­
ponents 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.
(3) Install rear thrust washer on rear planetary
gear (Fig. 70). 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. 70).
(5) Install assembled rear planetary and annulus
gear on intermediate shaft (Fig. 71). Verify that as­
sembly is fully seated on shaft.
(6) Install front thrust washer on rear planetary
gear (Fig. 72). Use enough petroleum jelly to hold
washer on gear. Be sure all four washer tabs are
seated in gear.
