41-0272024-06-04. Service bulletin. On certain Peterbilt, New Medium Duty chassis that are equipped with the optional engine intake air Pre-Filter (option code 3281830) the Pre-Filter may become clogged and cause premature failure/breach of the primary intake air filter. In some cases, a failed/breached primary filter can result in unusually high engine RPMs and high crankcase pressure. However, a failed/breached primary filter may not exhibit any of these symptoms. The immediate fix for this issue is to modify the Pre-Filter by removing the filter media from the base plate, and then reinstalling the modified Pre-Filter base plate.
