5. Expand output shaft bearing snap-ring (1) with
expanding-type snap-ring pliers. Then push output
shaft forward to release shaft bearing from locating
ring.
6. Lift gear case (2) up and off geartrain assembly (1).
7. Remove snap-ring (3) that retains rear bearing (2)
on output shaft (1).
8. Remove rear bearing from output shaft.
DIRECT CLUTCH, HUB AND SPRING
WARNING: The next step in disassembly involves compressing the direct clutch spring. It is extremely
important that proper equipment be used to compress the spring as spring forceisapproximately830
pounds. Use spring compressor tool 6227-1 and a hydraulic shop press with aminimum ram travel of 5-6
inches. The press must also have a bed that can be adjusted up or down as required. Release clutch spring
tension slowly and completely to avoid personal injury.

1. Mount geartrain assembly in shop press (1, 5).
2. Position Compressor Tool 6227-1 (6) on clutch hub
(3). Support output shaft flange with steel press
plates (4) as shown and center assembly under
press ram (1).
3. Apply press pressure slowly. Compress hub and
spring far enough to expose clutch hub retaining
ring (3) and relieve spring pressure on clutch pack
snap-ring.
4. Remove direct clutch pack retaining ring (3).

5. Remove direct clutch hub retaining ring (2).
6. Release press load slowly and completely.
7. Remove Special Tool 6227-1 (1). Then remove
clutch pack (3) from hub (2). Note the orientation of
the clutch discs. The clutch pack consists of 10
double-sided friction discs and they must be
installed in the same orientation as they were
removed.

2. Remove sun gear (5) and spring plate (3). Then
remove planetary thrust bearing (2) and planetary
gear (1).
3. Remove overrunning clutch assembly (1) with
expanding type snap-ring pliers. Insert pliers into
clutch hub. Expand pliers to grip hub splines and
remove clutch with counterclockwise, twisting
motion.

4. Remove thrust bearing from overrunning clutch
hub.
5. Remove overrunning clutch from hub.
6. Mark position of annulus gear and direct clutch
drum (1) for assembly alignment reference. Use
small center punch (3) or scriber to make align-
ment marks.
7. Remove direct clutch drum (2) rear retaining ring
(1).
8. Remove direct clutch drum outer retaining ring (1).

CLEANING
Clean the geartrain and case components with solvent. Dry all parts exceptthebearingswithcompressedair.Allow
bearings to air dry.
Do not use shop towels for wiping parts dry unless the towels are made from a lint-free material. A sufficient quan-
tity of lint (from shop towels, cloths, rags, etc.) could plug the transmission filter and fluid passages.
Discard the old case gasket and seals.Do not attempt to salvage these parts. They are not reusable. Replace any
of the overdrive unit snap-rings if distorted or damaged.
Minor nicks or scratches on components can be smoothed with crocus cloth. However, do not attempt to reduce
severescoringonanycomponentswithabrasive materials. Replace severely scored components; do not try to
salvage them.
INSPECTION
Check condition of the park lock components and the overdrive case.
Check the bushings in the overdrive case. Replace the bushings if severelyscored or worn. Also replace the case
seal if loose, distorted, or damaged.
Examine the overdrive and direct clutch discs and plates. Replace the discs if the facing is worn, severely scored,
or burned and flaking off. Replace the clutch plates if worn, heavily scored, or cracked. Check the lugs on the clutch
plates for wear. The plates should slide freely in the drum. Replace the plates or drum if binding occurs.
Check condition of the annulus gear, direct clutch hub, clutch drum and clutch spring. Replace the gear, hub and
drum if worn or damaged. Replace the spring if collapsed, distorted, or cracked.
Be sure the splines and lugs on the gear, drum and hub are in good condition. The clutch plates and discs should
slide freely in these components.
Inspect the thrust bearings and spring plate. Replace the plate if worn or scored. Replace the bearings if rough,
noisy, brinnelled, or worn.
Inspect the planetary gear assembly and the sun gear and bushings. If either the sun gear or the bushings are
damaged, replace the gear and bushings as an assembly. The gear and bushings are not serviced separately.
The planetary carrier and pinions must be in good condition. Also be sure the pinion pins are secure and in good
condition. Replace the carrier if worn or damaged.
Inspect the overrunning clutch and race. The race surface should be smoothand free of scores. Replace the over-
running clutch assembly or the race if either assembly is worn or damaged inany way.
Replace the shaft pilot bushing and inner bushing if damaged. Replace either shaft bearing if rough or noisy.
Replace the bearing snap-rings if distorted or cracked.
Check the machined surfaces on the output shaft. These surfaces should clean and smooth. Very minor nicks or
scratches can be smoothed with crocus cloth. Replace the shaft if worn, scored or damaged in any way.
Inspect the output shaft bushings. The small bushing is the intermediate shaft pilot bushing. The large bushing is the
overrunning clutch hub bushing. Replace either bushing if scored, pitted, cracked, or worn.
