The Honda 13228-890-003 Connecting Rod Bearing D (Yellow) is a genuine OEM component designed for a wide range of Honda generators, engines, and equipment including E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, EV4000, EW170, G400, GV400, and HT3810 applications. As a direct Honda OEM part, this bearing insert is manufactured to the same exacting tolerances as the original, ensuring the correct oil film clearance that the connecting rod depends on. The Yellow color code identifies a specific bearing size grade — matching that grade to your engine's crankpin and rod bore dimensions is essential before installation. Always verify your machine's serial number against the fitment table to confirm this is the correct grade for your unit.
Key Features
- Correct Bearing Grade — the Yellow color code denotes a precise size classification; using the right grade maintains the oil film clearance the connecting rod requires for proper lubrication and load distribution
- Genuine Honda OEM Quality — sourced directly from Honda, this bearing insert is produced to the same dimensional and surface-finish standards as the original, ensuring it seats and performs as the engine was designed
- Broad Fitment — covers Honda E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, EV4000, EW170, G400, GV400, and HT3810 equipment, including generators, welder generators, horizontal and vertical shaft engines, and a lawn tractor
- Serial Number Verification Recommended — Honda supersedes bearing grades at production breaks; check your unit's serial number against the fitment table to confirm part number 13228-890-003 and the Yellow grade are correct for your specific machine
- Engine Protection at the Core — a worn or out-of-spec connecting rod bearing causes knocking, accelerated crankpin wear, and eventual rod failure; replacing it with the correct grade restores proper clearance and protects the bottom end
The connecting rod bearing is a precision insert that sits between the connecting rod's big end and the crankshaft's crankpin journal. Its job is to support the tremendous forces generated during each combustion cycle while maintaining a thin, continuous film of oil between the rod and the crankpin — that oil film is what prevents metal-to-metal contact. Honda grades these bearings by color code to account for manufacturing tolerances in both the crankpin and the rod bore; the Yellow designation identifies a specific clearance range, and installing the wrong grade — too tight or too loose — leads to oil starvation, rapid wear, or bearing seizure. When this bearing wears, the result is a telltale rod knock that worsens under load, a warning that demands immediate attention to avoid catastrophic engine damage.
