26. ENGINE RUN-IN INSTRUCTIONS.
Following a complete overhaul or any major repair job involving the installation of piston rings, pistons, cylinder
liners, or bearings, the engine must be RUN-IN prior to release for service.
A typical run-in schedule is shown below.
NOTE
Before starting the RUN-IN or starting up the engine for any reason
following an overhaul, it is of extreme importance to observe the
instructions on "Preparation for Starting Engine First Time".
The dynamometer provides an excellent method of detecting improper tune-up, misfiring injectors, low
compression and other malfunctions, and may save an engine from damage at a later date.
The operating temperature within the engine affects the operating clearances between the various moving parts
of the engine and determines to a degree how the parts will wear. Normal coolant temperature (160185 ) should be
-
F
maintained throughout the RUN-IN.
