SECTION 9 − RUN-IN PROCEDURE
run_in1 6/96
9-1. Wetstacking
1 Welding Generator
Run diesel engines near rated
output during run-in period to prop-
erly seat piston rings and prevent
wetstacking. 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 dur-
ing 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 follow-
ing run-in procedures.
See the engine manual for addi-
tional engine run-in information.
