E01 BUDDY 125 CRANKCASE

The Genuine Buddy 125 crankcase diagram shows the complete lower engine assembly, including the crankcase halves, crankcase cover, oil drain plug, oil filter cover, oil filter gasket, crankshaft bearings, oil seals, reed valve assembly, intake tube, intake spacer, dowel pins, and mounting hardware. This diagram is used to identify OEM replacement parts for engine rebuilding, lubrication system service, intake repairs, and crankcase maintenance. The crankcase serves as the structural foundation of the Buddy 125 engine, housing the crankshaft, supporting the lubrication system, and providing mounting points for intake and engine components. Common repairs include replacing leaking oil seals or gaskets, servicing the oil filter assembly during routine maintenance, repairing intake leaks caused by damaged spacers or reed valve components, and rebuilding the engine after bearing wear or internal component failure.
