Onan Genuine Parts flanged main bearing, boxed as part number 101-0432, size designation .030 ("BEARING KIT"). Original McGraw-Edison-era Onan packaging.

Application: Onan engine / generator-set family. The exact Onan engine model, genset spec number, and journal size are not verified from the photographs — application is unverified and the item is sold by photographs, identifiers, and dimensions. Bearing size designations are not interchangeable; confirm the correct size for your crankshaft.

Condition: New old stock (NOS). The bearing shows bright machined surfaces with no running or wear pattern, only light handling marks and shop dust. The original box is aged, opened, and torn. No dimensional inspection or clearance check has been performed — measure against your crankshaft journal and the OEM clearance specification before installation.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.
