DISASSEMBLY/ASSEMBLY PROCEDURE SEQUENCE
THIS WORK PACKAGE COVERS:
General, Cleaning, Inspection, and Disassembly/Assembly Sequence Tables
GENERAL
The tables in this work package are provided as a guide for the orderly disassembly and
subsequent assembly of the AVDS-1790 engine. The work packages have been grouped in
sequential order. In some cases there is more than one work package in a group, in those cases
there is no preference as to which work package is to be done first, they can be accomplished
simultaneously. Before proceeding to the disassembly table, the exterior of the engine must be
cleaned and the oil must be drained. Go to Work Package 0031 for the engine oil draining
procedure.
CLEANING
1. See Work Package 0028 for General Cleaning Procedures.
2. Close all openings on the engine with waterproof tape or suitable plugs and thoroughly clean
all external parts and outer surfaces. Make sure no foreign material enters working parts of
engine assembly. Wash engine using water under pressure to remove mud and dirt. Remove
oil and grease using a stiff brush with cleaning solvent.
INSPECTION
All parts must be inspected with care. Replace parts if damage or wear exceeds allowable
limits.
1. See Work Package 0028 for General Inspection Procedures.
2. Do a general inspection of each assembly as it is removed from the engine to determine if
further disassembly is required.
