BREAK-IN DIESEL ENGINE (Except IH Diesel Engines)
The way you operate your new engine during the first 100 hours' service will have an important effect on the life of the engine and its parts. Its moving parts are closely fitted for long service, and even though all diesel engines are run on a dynamometer for several hours before they leave the factory, an additional period may
be required before uniform oil films are established between all mating parts.
During the first 100 hours' service:
1. Operate most of the time at one-half to three-
quarters throttle. Do not operate at maximum horsepower for more than five minutes at a time.
Do not idle the engine for long periods.
Keep a close watch on your instruments. Back
off on throttle if water temperature exceeds 190 degree F.
4. Drive in a gear low enough so that you can accelerate under any condition to prevent lugging your engine. DO NOT LUG THE ENGINE AT ANY TIME.
"During this break-in period, avoid full throttle starts and, if possible, abrupt stops. Gentle braking during the first hundred miles of operation will result in longer brake life and better future performance. Avoid hard stops especially during the first 250 miles of operation, since brake misuse during this period could sharply reduce future brake efficiency."
