Main BearingThe AC12231-B5010 is a main bearing supplied as an aftermarket replacement for forklift engine rebuilds. Main bearings support the crankshaft inside the engine block and take the brunt of combustion loads, so they need precise clearances and consistent material quality. Shops rebuilding lift truck engines order this part when bringing a worn crankshaft back into spec, and fleet managers stock it for scheduled overhauls on aging units. Working with the original description "BEARING KIT - MAIN STANDARD", this listing covers the bearing as referenced in OEM service literature.
