TRANSFER CASE 7D-27
Inspection and Repair
1. Make the necessary repair or parts replacement if
wear, damage or any other abnormal conditions are
found during inspection.
2. W ash 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. Appl
y
compressed air to each oil feed port and channel in
each case half to remove any obstructions or cleaning
solvent residue.

Inspection and Repair (Transfer Case
Assembly)
W hen wear, damage, or any other defects are observed
during the inspection, the part or parts must be repaired
or replaced. W ash all the parts with clean detergent, and
check that old oil, metallic particles, dirt, or foreign
materials are completely removed. Blow the air into oil
holes and grooves to remove foreign materials or
residual detergent.

Chain
• Check whether the face that contacts the sprocket is
free from excessive wear or damage. If defects are
observed, replace the part.
• If the chain interference mark is found on the inside
wall of the transfer cover or the chain is so slack that a
skipped engagement occurs between the chain and
sprocket, replace the chain.

Sprocket
• Check whether the sprocket tooth surface is
excessively worn or damaged, and there is evidence
of burrs, chipping, wear, or damage on the gear
spline. Remove minor flaws or scratches with oil
stone. If excessive wear or damage is observed,
replace the part.
• If excessive wear or damage is observed on the
sprocket inside sliding surface, replace the part.

Gear
• Check whether the gear tooth surface is excessively
worn or damaged, and there is evidence of burrs,
chipping, wear, or damage on the gear spline.
• Remove minor flaws or scratches with oil stone. I
f
excessive wear or damage is observed, replace the
part.

2-4 and Neutral Switch

• Check the continuity of 2-4 and Neutral switch.
If defects are observed, replace the 4H and 4L switch.
