Start By A. Separate the torque converter from
the transmission and from output transfer
gears. Note Cleanliness is an important factor.
Before the disassembly procedure, the exterior of
the component should be thoroughly cleaned. This
will help to prevent dirt from entering the
internal mechanism. NOTICE Care must be taken
to ensure that fluids are contained
during performance of inspection, maintenance,
testing, adjusting and repair of the product. Be
prepared to collect the fluid with suitable
containers before opening any compartment or
disassembling any component containing fluids.
3
Refer to Special Publication, NENG2500,
"Caterpillar Dealer Service Tool Catalog" for
tools and supplies suitable to collect and
contain fluids on Caterpillar products. Dispose
of all fluids according to local regulations and
mandates.
