SECTION 10 – RUN-IN PROCEDURE

run_in1 6/96

10-1. Wetstacking

1

Welding Generator

Run diesel engines near rated out-
put during run-in period to properly
seat piston rings and prevent wets-
tacking. See nameplate or rating
label to find rated output.

.

Do not idle engine longer than
necessary. Piston rings seat
faster if engine runs at weld/
power rpm, and the welding
generator is kept loaded during
run-in.

2

Engine Exhaust Pipe

Wetstacking is unburned fuel and
oil in the exhaust pipe and occurs
during run-in if the engine is run too
long at light load or idle rpm.

If exhaust pipe is coated with a wet,
black, tar-like substance, dry the
engine using one of the following
run-in procedures.

See the engine manual for addition-
al engine run-in information.
