Inspection and Repair
1. Make the necessary repair or parts replacement if
wear, damage or any other abnormal conditions are
found during inspection.
2. Wash all parts thoroughly in clean solvent. Be sure all
old lubricant, metallic particles, dirt, or foreign
material are removed from the surfaces of every part.
Apply compressed air to each oil feed port and
channel in each case half to remove any obstructions
or cleaning solvent residue.
Gears
1. Inspect all the gear teeth for signs of excessive wear
or damage and check all the gear splines for burrs,
nicks, wear or damage. Remove the minor nicks or
scratches on an oil stone. Replace any part exhibiting
excessive wear or damage.
Front Output Gear Inside Diameter
1. Use an inside dial indicator to measure the gear inside
diameter.

4D1–34
TRANSFER CASE (STANDARD TYPE)
2. If the measured value exceeds the specified limit, the
gear must be replaced.
Gear inside diameter
Standard : 48.000–48.013 mm (1.8898–1.8903 in)
Limit : 48.10 mm (1.894 in)
226RS040
Clutch Hub Spline Play
1. Set a dial indicator to the clutch hub to measured.
2. Move the clutch hub as far as possible to both the right
and the left.
Note the dial indicator reading.
3. If the measured value exceeds the specified limit, the
clutch hub must be replaced.
Clutch hub spline play
Standard : 0–0.1 mm (0–0.004 in)
Limit : 0.2 mm (0.008 in)
226RS042
Bearings
1. Inspect the condition of all the needles and ball
bearings. Wash bearings thoroughly in a cleaning
solvent. Apply compressed air to the bearings.
NOTE: Do not allow the bearings to spin. Turn them
slowly by hand. Spinning bearings may damage the
rollers.
2. Lubricate the bearings with a light oil and check them
for roughness by slowly turning the race by hand.
Ball Bearing Play
1. Use a dial indicator to measure the ball bearing play.
2. If the measured value exceeds the specified limit, the
ball bearing must be replaced.
Limit : 0.2 mm (0.008 in)
226RS043
Synchronizers
The synchronizer hubs and sliding sleeves are a selected
assembly and should be kept together as originally
assembled.
Clean synchronizer components with clean solvent and
air dry.
Inspect the components for the following:
Teeth for wear, scuffs, nicks, burrs or breaks.
Keys and springs for wear, cracks or distortion,
replace if these conditions are present.
If scuffed, nicked or burred conditions cannot be
corrected with a soft stone or crocus cloth, replace the
component.
Block Ring and Insert Clearance
1. Use a vernier caliper to measure the clearance
between the block ring and the insert.
2. If the measured value exceeds the specified limit, the
block ring and the insert must be replaced.
Block ring and insert clearance
Standard : 2.46–2.74 mm (0.097–0.108 in)
