The 3054 Emission Engine needs to be converted to an open circuit breather in certain 315B Excavators. Black smoke from the exhaust system caused by potential oil carryover from the breather into the induction system could cause high oil consumption and durability problems. To avoid oil consumption problems, the 3054 engine needs to be converted from a Closed Circuit Breather to an Open Breather Circuit.

Dear Caterpillar Product Owner:
The 3054 Emission Engine needs to be converted to an open circuit breather in certain 315B Excavators.

You will not be charged for the service performed.
Contact your local Caterpillar dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service. Please refer the dealer to their Service Letter dated September 6, 2004 when scheduling this service.
