Engine News SEBD9283, March 2000, "New Turbochargers Provide Increased Bearing Life". Disregard this reference article. See the following article for the correct information.Description of Change: New turbochargers are used on these engines. The new turbochargers have the following improvements:
new shaft bearings
a new bearing housing
a new retainer ringThe new bearings are retained in the bearing housing via a tab on the new retainer ring. The new turbochargers should provide improved service life for the bearings.A new service repair kit (bearing kit) for the turbocharger is also available.Adaptable To: The new turbochargers are effective with the following 3516 Engines: 25Z6656-UP, 27Z812-UP, 28Z653-UP and 29Z1353-UP. The new turbochargers are adaptable to earlier engines that have the listed serial number prefixes.The new turbochargers are direct replacements for the former turbochargers. The new service repair kit (bearing kit) can only be used with the new bearing housing. The former bearing kit can only be used with the former bearing housing. When the former turbochargers are serviced, the former bearing kit must be used.Table 1 lists the turbocharger part numbers. To find the proper part number for your application, verify your current engine rating and the corresponding test specification. Then use the TMI system in order to find the proper turbocharger group.
