Product Details
Westerbeke 037875 is a complete standard-size engine main bearing set for compatible Westerbeke BCG gasoline marine generator engines.
Main bearings support the engine crankshaft and maintain proper crankshaft alignment and oil clearance. Worn main bearings can contribute to low oil pressure, excessive crankshaft clearance, bearing noise, and internal engine wear.
This STD-size bearing set is intended for engines retaining standard crankshaft journal dimensions.
This listing is for Westerbeke 037875 standard main bearing set only.
Important Fitment Information
Verify Westerbeke part number 037875, generator model, crankshaft journal dimensions, and required bearing size before ordering.
Engines with a previously machined crankshaft may require an undersize bearing set instead of standard-size bearings.
