GENERAL.
a.
These general maintenance procedures and instructions contain general shop practices and specific methods you
must be familiar with to properly maintain your Diesel Engine Assembly, Hatz 2 G 40. You should read and
understand these practices and methods before performing any maintenance task.
b.
Before beginning a task find out how much repair, modification, or replacement is needed to fix the equipment as
described in this manual. Sometimes the reason for equipment failure can be seen right away and complete tear
down is not necessary. Disassemble equipment only as far as necessary to repair or replace damaged or broken
parts.
c.
The following applies to the "Initial Setup" section contained in all the maintenance-task paragraphs.
(1)
Materials, parts, and tools are not listed unless they apply to the procedure.
(2)
Personnel are listed under "Personnel Required" only if more than one technician is needed in order to
complete the task. If "Personnel Required" is not listed, it means that one technician can perform the task.
d.
Check all tags and forms attached to the Diesel Engine Assembly for any information about the reason it was
removed from service. Modification work orders and technical bulletins must also be checked for equipment
changes and updates.
e.
In some cases, a part may be damaged by removal. If the part appears to be good and other parts behind it are
not defective, leave it on and continue with the procedure. Here are a few simple rules:
(1)
Do not remove dowel pins or studs unless loose, bent, broken, or otherwise damaged.
(2)
Do not remove bearings or bushings unless damaged. If you need to remove them to access parts, pull
out bearings and bushings carefully.
(3)
Replace all gaskets, seals, lockwashers, cotter pins, preformed packings, and other locking hardware.
