Clevite CB-1238A — engine applications & dimensions

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.

2026 manufacturer catalogue, not a universal fitment promise

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.

Source-listed bearing records

11 records

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.

Use the reference correctly

Identify before comparing

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.

Measure the actual assembly

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.

Keep unresolved values unresolved

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.

Read the oil-clearance, material and installation reference →Check replacement evidence →Separate wheel, hub and seal vehicle reference →

Reference basis and limitations

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.
