Kyosho 74035-04 Crankcase Set for KE21V engine part  [KY-74035-04]

Crankcase Set for KE21V Engine

This crankcase set is a replacement engine housing designed specifically for the KE21V RC engine. It provides the structural enclosure for the crank assembly and internal components, restoring correct alignment and sealing after wear or damage.

Compatibility is limited to the KE21V engine family; confirm your engine code before ordering. The component is intended for hobby-grade nitro RC engine use only and is sized to RC scale dimensions.

Installation notes: remove the engine from the model, disassemble the top-end and internal components, and inspect bearings and seals for wear before fitting the new crankcase. Use correct fastener torque and thread-lock where recommended by your engine manual. If replacing a damaged crankcase due to impact or corrosion, inspect the crankshaft and connecting rod for straightness and fatigue.

Tuning and maintenance role: replacing a worn or cracked crankcase restores correct crankshaft alignment and compression behavior, which can reduce oil leakage and stabilize running characteristics. A service replacement helps maintain consistent idle and throttle response when combined with routine carburetor and head maintenance.
