Honda 13226-890-003 Connecting Rod Bearing B (Brown)

The Honda 13226-890-003 Connecting Rod Bearing B (Brown) is a genuine OEM component designed for a wide range of Honda generators, engines, a welder generator, and a lawn tractor, including G400 horizontal shaft engines, GV400 vertical shaft engines, E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, and EV4000 generators, the EW170 welder generator, and the HT3810 lawn tractor. Sourced directly from Honda, this bearing carries the exact sizing, grade, and tolerances specified for these applications. The Brown color code identifies this bearing's specific dimensional class — verify your engine's rod journal measurements and Honda's bearing selection chart before ordering, as multiple grades may be listed for the same engine family. As a genuine OEM part, this Connecting Rod Bearing B meets Honda's original design standards for clearance and load capacity at the connecting rod journal.

Key Features

• OEM Grade Bearing Tolerance — manufactured to Honda's exact journal clearance specification for the connecting rod, ensuring proper oil film thickness and load distribution at the crank journal
• Color-Coded Sizing Class — the Brown designation identifies a specific bearing thickness class; match this code to your engine's crankshaft and connecting rod journal measurements before installation to confirm the correct fit
• Broad Genuine OEM Coverage — fits G400 horizontal shaft engines, GV400 vertical shaft engines, E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, and EV4000 generators, the EW170 welder generator, and the HT3810 lawn tractor, including part number 13226-890-003
• Serial Number Verification Recommended — Honda supersedes bearing grades at production breaks; check your unit's serial number against the fitment table to confirm this is the correct class for your engine
• Critical to Engine Longevity — a bearing at the correct clearance maintains stable oil pressure at the rod journal; an undersized or oversized bearing accelerates wear on the crankshaft and connecting rod, leading to engine knock and eventual failure

The connecting rod bearing sits between the connecting rod's big end and the crankshaft journal, providing a precision running surface that allows the rod to rotate smoothly around the crank pin under combustion loads. A thin film of pressurized oil separates the bearing from the journal during operation, and the bearing's thickness class — indicated here by the Brown color code — determines the exact clearance that film must fill. When this bearing wears, scores, or is installed at the wrong clearance, oil pressure at the journal drops, metal-to-metal contact follows, and the crankshaft and connecting rod can sustain serious damage. Selecting the correct color-coded class and replacing this bearing at the intervals Honda specifies is one of the most direct ways to protect the long-term health of the engine.
