🔧 Part Overview: GOULD MS-405P-10 Main Bearing Set
This is a New Old Stock (NOS) main bearing set from GOULD, part number MS-405P-10, manufactured in the USA and dated October 1978. The packaging includes a handwritten note referencing “OLIVER,” strongly suggesting fitment for Oliver tractors or industrial engines. The “P-10” suffix typically denotes a 0.010" undersize, meaning the bearings are designed for crankshafts that have been ground down during an engine rebuild.
🛠️ Application & Fitment
Based on cross-referenced listings and aftermarket equivalents (e.g., Clevite MS-405P-10), this bearing set fits:
-
Ford V6 engines, including:
-
3.5L DOHC and 3.7L DOHC (2007–2011)

The dual references suggest this part number may have been reused across platforms or that GOULD supplied bearings for multiple OEMs. For precise fitment, journal dimensions and casting numbers should be verified.
