CORE AS-RADIATOR 2984933 - Caterpillar

ACTION REQUIRED
Nominal wear is to be expected on valve train components during the course of engine life. Spalling and pitting may be present but do not necessarily indicate an eminent failure. A failure is considered when a machine is low on power or the upper valve train wear is progressing towards a low power complaint or mechanical failure.
