CLEANING

CLEANING-TRANSFER CASE MP140

The use of crocus cloth is permissible where necessary, providing it is used carefully. When used on shafts, or
valves, use extreme care to avoid rounding off sharp edges. Sharp edges are vital as they prevent foreign matter
from getting between the valve and valve bore.

Do not reuse oil seals, gaskets, seal rings, or O-rings during overhaul. Replace these parts as a matter of course.

Also do not reuse snap rings or E-clips that are bent or distorted. Replace these parts as well.

Lubricate transfer case parts with Mopar® ATF+4 ATF, Automatic Transmission Fluid, during overhaul and
assembly. Use petroleum jelly to prelubricate seals, O-rings, and thrust washers. Petroleum jelly can also be
used to hold parts in place during reassembly.

Clean the case in a solvent tank. Flush the case bores and fluid passages thoroughly with solvent. Dry the case
and all fluid passages with compressed air. Be sure all solvent is removed from the case and that all fluid
passages are clear.

INSPECTION

INSPECTION-TRANSFER CASE MP140

Inspect the case for cracks, porous spots, worn bores, or damaged threads. Damaged threads can be repaired
with Helicoil® thread inserts. However, the case will have to be replaced if it exhibits any type of damage or
wear.

ASSEMBLY

ASSEMBLY-TRANSFER CASE - MP140

NOTE:

Do not use shop towels or rags to dry the case (or any other transmission
component) unless they are made from lint-free materials. Lint will stick to case
surfaces and transmission components and circulate throughout the
transmission after assembly. A sufficient quantity of lint can block fluid
passages and interfere with valve body operation.
