3. 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 disassembied or c1eaned 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.
GENERAL
3.2 Reassembly
(1) Wash all engine parts, except oil seals, O-rings,
rubber seals, etc. in c1eaning 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, "Maintenance Standards".)
(4) Use a torque wrench to tighten parts when
specified tightening torques are required. (Refer
to section 2, of Group 2, "Maintenance
Standards".)
(5) Replace all gaskets and packing. Apply
appropriate amount of adhesive or liquid gasket
when required.
