KE21V Crankcase Set Kyosho 74035-04  [KY-74035-04]

Overview: Crankcase for KE21V

This crankcase set is a replacement engine housing tailored for the KE21V RC engine. It secures the crank assembly and internal components, helping to re-establish correct alignment and sealing after wear or damage.

Compatibility is confined to the KE21V engine family; always confirm your engine code prior to purchase. The component is made for hobby-grade nitro RC engines and is produced to RC scale sizing.

Installation notes: remove the engine from the vehicle, dismantle the top-end and internals, and inspect bearings and seals for wear before fitting the replacement crankcase. Adhere to recommended fastener torques and use thread-lock where specified by your engine documentation. When a case is replaced following impact or corrosion, examine the crankshaft and connecting rod for straightness and fatigue.

Tuning and maintenance role: replacing a worn or cracked crankcase restores crank alignment and compression behavior, which can reduce oil leakage and help maintain steady idle and throttle characteristics alongside regular carb and head maintenance.
