Identification Guide
Schwitzer Turbos
Robust turbochargers engineered for heavy-duty applications, trusted in commercial and industrial sectors.
How to Find the Number
Part Number Details
Once you find the identification name plate there are several possibilities:
1. On the name plate there is a Schwitzer part number, usually (directly after the p/n or part number), where the turbo is already identified.
2. Only the O.E.M. part number (that of the maker of the engine) appears on the name plate, this is normally the case with CATERPILLAR, DETROIT DIESEL, JOHN DEERE, PERKINS and K.H.DEUTZ, this is why we need to search for the crossing using the search of this Web site, introducing the O.E.M. part number and searching by O.E.M. part number (it should maintain the same style with spaces, hyphens, etc...).
Data Plate Reference
What to Check
The legacy Ace Turbo guide used manufacturer data plate examples to show exactly where the identifying number normally appears. Use the image as a quick visual reference, then match the number format against the notes above.
