ACTION REQUIRED
Show/hide table
| Before completing the rework, please review the safety actions in the Operation and Maintenance Manual for the engine. This Program has been approved by the Environmental Protection Agency. As such it is a mandatory requirement for a Field Fix Rework label to be affixed to every reworked engine. A label, Reference CPI295973_RW001, must be obtained from EngineCertificationHelp@perkins.com identifying Reference CPI295973_RW001 and the machine and engine serial number. The dealer initiating the rework must ensure the label has been received before the rework can be carried out. Adhere the field fix label onto the engine front cover. The label is classified as a permanent part and must NOT be removed during any service or maintenance activity. The label is a security type label which will be damaged / destroyed by any attempt at removal. Prior to fitting the label be sure that the mounting location is free from debris, loose materials and grease. The area can be degreased using a suitable proprietary cleaner prior to label fitting. Please choose one of the following actions: 1. If turbocharger has not failed, reflash the engine ECM with the new software. The new software holds the engine at a safe speed until oil pressure is detected. 2. If the turbocharger has failed, replace the turbocharger and reflash engine ECM with new software. For detailed instructions on removing and installing the turbocharger refer to KENR9105, "Turbocharger - Remove - First Stage Turbocharger" and "Turbocharger - Install - First Stage Turbocharger". |
