The application path provided serves as a verification clue rather than a confirmed fitment confirm. Cross-check part number 149790 against your service documentation or existing unit to confirm the correct replacement application for your CAT 3306 engine.

Technical Notes

The 149790 turbine housing features a cast metal body with a rough, matte black exterior finish and a machined, polished circular turbine inlet. Visible structural details include a rectangular flange with two large, rounded-rectangular exhaust ports and a four-bolt flange pattern at the corners. A small mounting tab is visible on the upper side of the housing body. These visual characteristics help buyers confirm the physical configuration matches their existing 4LF504 unit. Verify the V-band clamp size and profile against your current housing to ensure proper sealing on CAT 3306 applications. Check stud and nut thread pitches using your OEM service manual or existing unit measurements before installation.
