PROBLEM
Some Reman turbocharger cartridges were built with the wrong heat shield. The proper heat shield should not have a taper on the outside diameter (OD) from top to bottom. The taper on the OD could disrupt the exhaust gas flow and cause low boost pressure.
ACTION REQUIRED
Inspect the heat shield under the turbine (hot) wheel on all 0R6797 Turbocharger Cartridges in dealer parts stock to determine if it has a taper on the OD. Refer to Image1.
- If the heatshield does not have a taper, no further action is required. Repackage the turbocharger cartridge in its original packaging, mark the outside of the package to indicate that the part has been inspected according to this service letter, and return the part to dealer parts stock.
- If the heatshield does have a taper on the OD as shown in Image1, remove the turbocharger cartridge from dealer parts stock.
