Sierra 18-1361 Rod Crank End Bearing - Replaces OMC/Evinrude-Johnson 387787

The Sierra 18-1361 is a rod crank end bearing engineered for outboard powerhead rebuilds, replacing the original equipment connecting rod bearing used on Evinrude/Johnson (OMC) outboard engines. This bearing rides at the crank end of the connecting rod, supporting the rotating assembly where the rod journals onto the crankshaft, and is a standard wear item during a lower-end or powerhead overhaul. Each Sierra bearing is manufactured to meet or exceed the quality of the original equipment part it replaces, making it a direct fit for machinists and technicians rebuilding OMC-based powerheads.

The 18-1361 is precision machined to close tolerances required for proper crankshaft clearance and smooth rotation. Because rod bearings are fit-specific to the engine and rod journal size, always confirm the OE part number your engine originally used before ordering. This bearing is sold to replace OMC/Evinrude-Johnson part number 387787.
