The Break In Period
The diesel engine must be broken-in, avoiding heavy loads (no greater than 75%), for a
period of twenty (25) hours to ensure proper operation of the generator set. After the
initial break-in period, engine lubricating oil must be changed, cylinder head nuts torque
must be checked, and intake and exhaust valve clearances must be checked and
adjusted.
Current technology provides the means of manufacturing engine parts with
unimaginable precision however they still far short of achieving the near perfect fit that a
proper break-in will provide. Break-in, is the allowance of the machined parts in the
engine engine to conform to each other. This conforming or mating specifically of the
ring and cylinder surfaces is the ultimate goal of a proper break-in. Mating these two
specific parts will produce a very tight seal in each cylinder. A tight seal is very important
because of the intense pressure diesel engines operate under. Mating helps prevent the
escape of unburned fuel and pressurized gasses into the crankcase, while further
preventing crankcase oil from entering the cylinder above the top compression ring. The
blow by also causes a loss of pressure and results in lack of power.
It is normal to find metal shavings trapped in your oil filter during this break in process.
Clean your oil filter normally.
Friction causes heat and until the break in occurs extra heat and most of the ware and
tear will happen during this period. Break in your engine before using it! Don't forget oil
will become contaminated faster because of combustion blow by fumes and metal that
is ground away during the mating process. The oil should be changed at at the first 25
hours. This is an important time for an engine. You should not subject the engine to
significant loading for the first 25 hours or more however some load IS desirable since
the heat and friction is also needed for the break in to occur. Excessive heat will burn oil
and cause it to harden leaving an enamel like residue on the cylinder wall, commonly
known as oil glazing and prevents the mating from occurring so small gaps between
rings and cylinder surfaces will never seal. The same applies to use synthetic oil during
the break in period. It will also prevent break in from happening. Only use synthetic oil
after the break in period. A
moderate loading is the key to a proper break in . 1/2 the
rated power may be ideal. While some manuals suggest decreasing the RPM it is not
easy to do on generator motors since they have a fixed run or stop position that locks
into place on the throttle. If you can, secure it for this process for a break in period so
are running it at half the RPM you will benefit from it in the long run. Obviously you can
not use the generator until the normal speed is restored.
Improper Generator Use - Wet Stacking
"Wet Stacking" happens when a diesel engine operates below the rated output level
the engine starts over-fuel or "wet stack". Diesel engines are designed to operate with a
load and operate more efficiently in the 70 to 80% range of rated output. When a diesel
