Kyosho KE21V 74035-09 Maintenance screw set for engine  [KY-74035-09]

Maintenance screw set for KE21V engine

This maintenance screw set is intended as replacement hardware for the KE21V engine in RC models. It serves as a straightforward spare parts option for routine engine service, allowing builders and mechanics to replace worn or lost fasteners during disassembly and reassembly.

Compatibility is limited to the KE21V engine as stated, and the set should be treated as RC-scale accessory hardware rather than as general-purpose fasteners for other assemblies. Use the screws when performing scheduled engine maintenance, inspection, or when preparing an engine for tuning adjustments.

The role of this screw set in tuning and upkeep is primarily preventative: ensuring correct fastener condition helps maintain consistent component alignment and reliable reassembly after carburetor, head, or crankcase servicing. Take care to secure screws evenly and avoid over-torquing to prevent thread damage on engine housings.

For hobbyists maintaining a KE21V-equipped model, this maintenance screw set provides a direct replacement option to keep engine service and tuning workflow uninterrupted.
