Back Plate Set for KE21V Engines 74035-07 Kyosho  [KY-74035-07]

Service role of the Kyosho 74035-07 back plate

This back plate is a replacement component made to fit KE21V engines and restore the rear crankcase interface. It addresses wear or deformation that compromises sealing or bearing alignment.

The part seals and locates the crankcase rear and forms the mounting plane for adjoining components. A defective plate can permit oil leaks, reduce crankcase pressure, or misalign the crankshaft and bearing seats. Fitting a correct replacement returns the assembly to its intended geometry without altering internal timing.

Installation follows common glow-engine rebuild practice: remove exhaust and cooling head where required, drain fluids, and unbolt the rear cover in the correct order. Clear gasket remnants, prepare mating faces, and install the new plate. Tighten fasteners to specified torque figures and verify bearing seating and shaft endplay after reassembly.

Consider this part a routine maintenance item rather than a performance modification; it restores factory fitment to keep engine behaviour predictable across services. Regularly inspect the sealing face during maintenance to prolong service life.

Ideal for KE21V engine rebuilds, the 74035-07 back plate helps reestablish sealing and alignment to maintain dependable engine operation in model use.
