Two New-Style Connecting Rods (Matched Pair) for Onan B and P Series 16 HP Twins This listing includes two new-style standard connecting rods, a matched pair for both cylinders of the Onan twin-cylinder engine. They replace Onan part number 114-0394 and use the solid-beam new-style design that supersedes the older 114-0300 / 170-4444 rod. The rods are gravity cast. Fitment Fits Onan 16 HP B-series and P-series engines: B43, B43E, B43G, B43M, BF, BFA, BFAB, P216, P216G, P216V, OL16, and LX720. Old-Style vs New-Style - Important for Balance New-style rods have a solid lower beam; old-style rods have a cast hole in the lower end. Compare your rod to the product images. If your engine currently has old-style rods, replace both rods with this pair so the engine stays balanced - do not run one old and one new rod. If you already have new-style rods and need only one, a single-rod version is available separately. Size, Torque, and Related Parts These are standard big-end rods for a standard crankpin journal. If the crankpin has been reground undersize, order the matching undersize rods (114-0394-10 for .010 in, or 114-0394-20 for .020 in). Torque to 30 Nm (22 ft-lb / 265 in-lb) - note this differs from the original Onan specification. This engine family is also served by piston ring sets, gasket sets with crankshaft seals, camshaft bearings, and complete rebuild kits.
- Two new-style standard connecting rods, a matched pair for both cylinders of the Onan B-series or P-series twin. Each is the solid-beam new-style design that replaces Onan 114-0394 (superseding the older 114-0300 / 170-4444 style).

- Balance note: new-style rods have a solid lower beam; old-style rods have a cast hole in the lower end. If your engine has the old-style rods, replace both with this pair to keep the engine balanced - do not mix old and new. If you already run new-style rods and need only one, a single-rod version is available.
- Standard big-end size for a standard crankpin journal. If the journal has been reground undersize, order the matching undersize rods (114-0394-10 or 114-0394-20) instead. Torque these rods to 30 N-m (22 ft-lb / 265 in-lb), which differs from the original Onan specification.
