Application & Compatibility

Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:

• MACK > MACK TRUCK > MACK EM7-300
• JOHN-DEERE > JOHN-DEERE 6081T
• MACK > E7 354 HP
• MACK > E7 400 HP
• MACK > E7-275 > 330

Reference applications for the 173385-R core include MACK EM7-300, MACK E7 354 HP, MACK E7 400 HP, MACK E7-275 330, MACK E7-400, and John Deere 6081T. These paths serve as verification clues rather than confirmed fitment. Buyers should cross-check the old turbo label against OEM reference numbers 178432-R and 174832-R. Verify the specific engine code, horsepower rating, and production year before ordering to ensure the 173385-R core matches your unit.

Technical Notes

The 173385-R core assembly features a central shaft connecting the compressor and turbine wheels within a cylindrical bearing housing. Visible machined surfaces and a green alignment mark on the compressor wheel aid in visual inspection. This configuration supports standard turbocharger core replacement workflows. Buyers should verify the specific engine variant, such as MACK E7 354 HP or 400 HP, against the old turbo label. Cross-checking OEM reference numbers 178432-R and 174832-R helps confirm the correct application before ordering.
