Tips on Disassembly and Reassembly

This service manual covers recommended procedures to
be followed when servicing diesel engines. It also
contains information on special tools required and basic
safety precautions.
It is the responsibility of service personnel to be
familiar with these requirements, precautions and
potential hazards and to discuss these points with their
foreman or supervisor.
Study this manual carefully and observe the following
general precautions to prevent serious personal injury
and to avoid damage to the engine, equipment and
parts.

3.1 Disassembly

(1) Use the correct tools and instruments. Serious
injury or damage to the engine can result from
using the wrong tools and instruments.
(2) Use an overhaul stand or work bench if necessary.
Also, use assembly bins to keep the engine parts in
order of removal.
(3) Lay down disassembled or cleaned parts in the
order in which they were removed. This will save
you time at reassembly.
(4) Pay attention to the marks on assemblies,
components and parts for positions or directions.
Put on your own marks, if necessary, to aid

reassembly.

(5) Carefully check each part for faults during removal
or cleaning. Signs of abnormal wear will tell if
parts or assemblies are functioning improperly.
(6) When lifting or carrying heavy parts, get someone
to help you if the part is too awkward for one
person to handle. Use jacks and chain blocks when
necessary.
3.2 Reassembly
(1) Wash all engine parts, except oil seals, O-rings,
rubber seals, etc. in cleaning solvent and dry them
with compressed air.
(2) Use only the correct tools and instruments.
(3) Use only good quality lubricating oils and greases.
Be sure to apply a coat of oil, grease, or sealant to
parts as specified. (Refer to section 3 of Group 2.)
(4) Use a torque wrench to tighten parts when specified
tightening torques are required. (Refer to section 2
of Group 2.)
(5) Replace all gaskets and packing. Apply appropriate
amount of adhesive or liquid gasket when required.
