(4) Run-In Procedure
The procedure outlined below will follow the order of
the sample Engine Test Report (see page 5-926).
(a) Pre-Starting
1. Fill the lubrication system.
2. Prime the fuel system.
3. A preliminary valve clearance adjustment
must be made before the engine is started.
4. A preliminary injector timing check must be
made before starting the engine.
5. Preliminary governor adjustments must be
made.
6. Preliminary injector rack adjustment must be
made.
(b) Basic Engine Run-In
1. The operator should be observant at all times,
so that any malfunction which may develop
will be detected. Since the engine has just
been reconditioned, this run-in will be a test of
the workmanship of the serviceman who per-
formed the overhaul. Minor difficulties should
be detected and corrected so that a major
problem will not develop.
2. After performing the preliminary steps, be
sure all water valves, fuel valves, etc. Are
open. Also inspect the exhaust system, being
sure that it is properly connected to the
engine.
Always start the engine with
minimum dynamometer resistance.
