Look up source-listed Clevite engine bearing parts, their engine/year conditions, set relationships and available shop dimensions. Preserve the engine version and catalogue notes before comparing a candidate.
Selections apply immediately; the button also works without JavaScript. Use a full engine code or part number. Displacement alone can match several different engine families.
Source: MAHLE/Clevite EB-20-26 engine-bearing catalogue. Entries retain the catalogue make section, application conditions and printed page. A make heading groups source applications; it is not proof that every engine listed was manufactured by that vehicle brand.
Numbers are Clevite references, not SKF/NTN cross-references. A set, a member shell and a separate thrust washer are different items. Unresolved or conflicting dimensions remain unavailable instead of being guessed.
3.8L 231 CID OHV 12V V6 General Motors VIN Code: '2' (1979) 3.8L 231 CID OHV 12V V6 General Motors LD5 VIN Code: 'A' (1978-1984)
Catalogue section: GMC TRUCK · Engine block 40. Match the code, year/VIN limits and each part's additional notes.
Shop dimensions are inches, including rows for metric engines. These are standard-size source dimensions, not permission to use a listed oil clearance in a different engine.

Keep engine code, production year, VIN qualifiers, bearing position and the existing shell markings. A 350, 1.8 or 4.6 label is not a unique engine identification.
Standard journal dimensions do not describe a worn or reground shaft. Verify the installed housing, required repair size and oil clearance with the engine-specific procedure.
Empty dimensional fields can reflect set-only entries, incomplete source rows or conflicts. They do not mean zero clearance, and another entry's values are not a substitute.
This independent lookup reorganises factual entries from the 2026 MAHLE/Clevite engine-bearing catalogue. The original source fingerprint, extraction record and application block are retained privately. The catalogue source is not a guarantee of current stock, current vehicle approval or complete coverage of every engine. BearingScope does not sell these parts or provide a rebuild service.
