Honda 13225-890-003 Connecting Rod Bearing A (Black)

The Honda 13225-890-003 Connecting Rod Bearing A (Black) is a genuine OEM component designed for a wide range of Honda generators, engines, a welder generator, and a lawn tractor, including the E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, EV4000, EW170, G400, GV400, and HT3810. As a factory-original part, this bearing is manufactured to the same specification as the unit it replaces, ensuring the correct clearances and fit within the connecting rod assembly. The Black color designation identifies this specific size variant — confirm it matches your engine's original bearing before ordering, as Honda uses bearing color codes to denote running clearances. Always cross-reference your unit's serial number against the fitment table to confirm this is the correct bearing for your application.

Key Features

• OEM Bearing Specification — genuine Honda construction ensures the correct oil-film clearance between the connecting rod journal and crankpin, which is critical for proper lubrication and load distribution at the rod
• Color-Coded Variant — the Black designation is Honda's size classification for this bearing; match this code to your engine's original bearing to confirm you have the right running clearance for your crankshaft
• Broad Fitment Coverage — fits Honda E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, and EV4000 generators, the EW170 welder generator, G400 horizontal shaft and GV400 vertical shaft engines, and the HT3810 lawn tractor
• Serial Number Verification Recommended — Honda supersedes bearing specifications at production breaks; check your unit's serial number against the fitment table before ordering to ensure part number 13225-890-003 is correct for your specific machine
• Engine Protection at the Core — a worn or out-of-tolerance connecting rod bearing allows excessive crankpin movement, leading to knocking, oil pressure loss, and accelerated internal wear; replacing it restores proper rod-to-crank contact

The connecting rod bearing sits between the connecting rod's big end and the crankshaft crankpin, forming the critical rotating interface that transfers the piston's power stroke into crankshaft rotation. It relies on a thin film of pressurized engine oil to prevent metal-to-metal contact under load — correct clearance is everything, which is why Honda color-codes bearings by size. When this bearing wears beyond its service limit, clearance grows, oil pressure drops at the rod journal, and the characteristic knock of a failing bottom end follows; left unaddressed, rod failure is the result. Replacing it with the correct OEM-specified bearing restores the designed clearance and protects the crankshaft from further damage.
