The Honda 13227-890-003 Connecting Rod Bearing C (Green) is a genuine OEM replacement built for E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, EV4000 generators, the EW170 welder generator, G400 horizontal shaft engines, GV400 vertical shaft engines, and the HT3810 lawn tractor. As a direct Honda OEM component, this bearing is manufactured to the same specifications as the original, ensuring the correct fit and bearing clearance for engines across this fitment range. The Green color code identifies this as the "C" grade variant — match it to the color-coded grade stamped or specified in your engine's service documentation before ordering.
Key Features
- OEM Bearing Grade — the Green "C" grade designation reflects a specific bearing clearance tolerance; using the correct grade is essential to maintaining proper oil film and rod-to-crankpin running clearance in the engine
- Genuine Honda OEM Part — manufactured to Honda's original specifications under part number 13227-890-003, not an aftermarket approximation, so dimensional accuracy is assured
- Broad Fitment Across Honda Families — fits E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, EV4000 generators, the EW170 welder generator, G400 horizontal shaft engines, GV400 vertical shaft engines, and the HT3810 lawn tractor, including multiple production serial ranges
- Verify Your Grade Before Installation — Honda engines use color-coded bearing grades (Green, Black, Brown, etc.) determined by crankpin and rod bore measurements; confirm the C grade is correct for your engine's specifications before fitting this part
- Critical to Engine Longevity — a worn or incorrect connecting rod bearing leads to increased crankpin wear, oil pressure loss, and eventual rod knock; installing the right grade bearing restores proper lubrication and protects the crankshaft
The connecting rod bearing sits between the connecting rod's big end and the crankshaft crankpin journal, allowing the rod to rotate smoothly around the crank as the piston moves up and down. It relies on a thin film of pressurized engine oil to prevent metal-to-metal contact — if the bearing wears, that oil film breaks down, generating heat and accelerating damage to both the rod and the crankpin. Honda assigns color-coded grades to these bearings to account for manufacturing tolerances in the crankpin and connecting rod bore; fitting the wrong grade results in either excessive clearance, which starves the journal of oil pressure, or insufficient clearance, which prevents the oil film from forming at all. When this bearing is worn, noisy, or seized, replacing it with the correct OEM-grade component is essential to restoring the engine's bottom-end integrity.
