200 ENGINE INSTALLATION & TESTING
Page 8-5
FUEL SYSTEM
1. Check fuel system to ensure that all
connections are tight.
2. Remove any trapped air by operating
manual priming pump, if equipped, located
on the side of injection pump (V-MAC only).
Prime the fuel system with clean, Grade 2D
diesel fuel (DF-A).
3. Check injection pump timing. Injection
pump-to-engine timing must be set for the
specific engine. See Engine Identification
Plate or Tune-Up manual for specifications.
Engine Operational Check
1. Remove all tools from the engine
compartment.
2. Connect battery cables (negative cable last).
3. Clear work area of debris and personnel.
4. Start the engine. Check for leaks and
monitor gauges for satisfactory oil pressure,
etc.
5. After several minutes, shut the engine down.
Check fluid levels and fill to capacity before
restarting engine.
6. Refer to the following Rebuilt Engine Run-In
Procedures for testing procedures.
REBUILT ENGINE RUN-IN
PROCEDURES
Description
The durability and service life of a rebuilt engine
is directly related to its initial run-in following
overhaul. After a complete overhaul or any major
repair job involving installation of piston rings,
pistons, cylinder sleeves or bearings, the engine
must be run-in prior to release for service.
Run-in procedures vary depending on method
used (i.e., engine dynamometer, chassis
dynamometer or highway run-in). Regardless of
method, however, always properly prepare
engine before starting it for the first time.
Run-In Check
Install any additional instrumentation needed for
run-in method selected.
The operator should be familiar with correct,
established procedure for checking chassis
power before using chassis dynamometer
method for run-in (refer to applicable chassis
dynamometer operation procedures).
The operator must be observant throughout the
entire run-in procedure, in order to detect any
problems that develop. Constantly monitor the
instrumentation displaying functions of the engine
and support systems, and record all readings.
If, during run-in, the engine develops any of the
following abnormal running characteristics, shut it
down immediately. Investigate and correct the
problem before continuing run-in procedure.
Always investigate the following conditions:
앫 Unusual noises such as knocking, scraping,
etc.
앫 A significant drop in engine oil pressure.
앫 A significant rise in coolant temperature,
exceeding 240°F (116°C).
앫 A significant rise in oil temperature that
exceeds 240°F (116°C).
앫 An exhaust temperature that exceeds
maximum acceptable limit for the specific
engine involved, as measured by a
pyrometer (if applicable).
앫 Any oil, coolant or air inlet system leaks.
