Kyosho 74035-04 Crankcase Housing for KE21V Engine  [KY-74035-04]

Engine Housing Details for KE21V

This crankcase set provides a direct replacement housing for the KE21V RC engine. It encloses the crank and internal parts, restoring alignment and sealing characteristics after wear or accidental damage.

Compatibility applies only to the KE21V engine family; verify your specific engine code before ordering. The item is designed for hobby-grade nitro RC engines and matches typical RC engine dimensions.

Installation notes: remove the engine from your model, disassemble the top-end and internals, and inspect bearings and seals for wear prior to fitting the new crankcase. Follow recommended torque values and use thread-lock where the manual suggests. If replacing a case due to impact or corrosion, check the crankshaft and conrod for straightness and fatigue cracks.

Tuning and maintenance role: a sound crankcase helps maintain correct crankshaft alignment and compression, reducing oil seepage and improving idle consistency when combined with regular carburetor and head maintenance.
