The Honda 13212-ZG3-003 Connecting Rod Bearing B (Black) is a genuine OEM replacement designed for EB12 generators, GD410 horizontal shaft diesel engines, and H6522 compact tractors. As an authentic Honda component, this bearing is manufactured to the exact tolerances Honda specifies for these applications, ensuring proper clearance and load distribution at the connecting rod journal. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes bearing grades at production breaks — the Black color code identifies this specific clearance grade and must match what your engine requires.
Key Features
- Grade-Specific Fit — the Black color code designates a precise bearing clearance grade; selecting the correct grade is essential for proper oil film thickness and crankshaft protection
- Genuine OEM Construction — manufactured by Honda to original equipment tolerances, maintaining the bearing-to-journal clearance that correct lubrication depends on
- Broad Cross-Equipment Fitment — covers EB12 generators, GD410 horizontal shaft diesel engines, and H6522 compact tractors; verify your serial number to confirm this grade applies to your unit
- Critical Wear Component — a worn or out-of-tolerance connecting rod bearing causes knocking, oil pressure loss, and accelerated crankshaft damage; replacing it at the correct service interval protects the bottom end
The connecting rod bearing sits between the connecting rod's big end and the crankshaft journal, forming a thin oil-film interface that lets the rod pivot smoothly as the piston travels up and down. Without adequate bearing clearance and an intact bearing surface, the oil film breaks down, metal-to-metal contact follows, and the crankshaft journal wears rapidly. Honda designates connecting rod bearings by color-coded grades — Black, Brown, and others — to match specific journal and bore diameter combinations measured during engine assembly or rebuild. Using part number 13212-ZG3-003 confirms you are installing the Black-grade bearing Honda specifies for the matching journal dimension, restoring the clearance the lubrication system was designed around.
