Sierra 18-1374 Wrist Pin Bearing for Evinrude/Johnson Outboards, Replaces OMC 395627

The Sierra 18-1374 is a wrist pin bearing built for Evinrude/Johnson outboard powerhead rebuilds. It sits at the connecting rod's wrist pin location and is manufactured with a machined finish for a precise, consistent fit. Sierra engineers this bearing to meet or exceed the quality of the original equipment part it replaces, giving rebuilders a reliable alternative to sourcing a discontinued or hard-to-find OE component.

The 18-1374 cross references directly to OMC/Evinrude-Johnson part number 395627, as well as GLM 16220, Mallory 9-51103, and Wiseco W5217, so it can be ordered against any of those interchange numbers. Each engine application uses four of these wrist pin bearings, and Sierra groups this part alongside related bearings for the same connecting rod and crankshaft assembly, including the 18-1353 center main bearing, 18-1395 lower crankshaft bearing, and 18-1361 rod crank end bearing, which are commonly serviced together during a full powerhead rebuild.

At just 0.39 x 0.39 x 0.39 inches and 0.07 pounds, the 18-1374 is a small but critical wear component. Installing it correctly requires disassembling the connecting rod and piston, so it is typically handled during a complete engine teardown rather than as a standalone repair.
