🛠️ PRO TECH TIP FOR MECHANICS (LH / RH Universal):
Caterpillar V-configured engines utilize a dual-turbo setup. However, the left-side (1W5285) and right-side (1W5286) share the exact same internal components. These include the Cartridge (6N7960), Compressor Housing (6N7959), and Turbine Housing (6N9910).
Consequently, the only difference is the housing rotation angle. Therefore, you can easily loosen the clamps on this unit to adjust the angle for either side perfectly.
