🛠️ Service Notes

• Unusually for a main bearing, this family runs standard plus 0.25 and 0.50 mm OVERSIZE rather than undersize — that suits a machined housing bore, not a reground journal, so read the workshop procedure before ordering
• Its superseded number is also catalogued as a bushing, which supports the oversize housing reading
