2W4226 Turbocharger Oil Supply Conversion Group is a replacement for the turbocharger lubrication valve, which is no longer needed on the above machines. If the turbocharger lubrication valve is installed backward, unfiltered (not clean) oil will be permitted to flow to the turbochargers at all times during operation. Installation of the conversion group will prevent this and still give the correct lubrication to the turbochargers. To install the conversion group, see the instructions that follow.
(1) Remove tube assembly (1) and the hardware. Make a replacement of the bolts that held the clip brackets in position with shorter bolts as necessary. Remove elbow (2) and connector (3). Make a replacement of connector (3) with a 2B858 Plug in flange (4). Remove tube assembly (5), tee (6) and the gasket. Keep the bolts that held tube (5) to the turbocharger.
