Kyosho KE21V Back Plate Set Model 74035-07  [KY-74035-07]

What the 74035-07 back plate replaces

This back plate set is produced to replace the rear cover on KE21V engines, reinstating the sealing face and the locating surface for adjoining components. It is suitable for rebuilds where the original plate shows wear or deformation.

Its function is to seal the crankcase rear and to position the crankshaft and related parts correctly. When the back plate is compromised you may see oil seepage, altered crankcase pressure, or misaligned bearings. Fitting a correct replacement recovers the intended assembly geometry without modifying timing or internal clearances.

Installation is performed following normal glow-engine rebuild practice: remove the exhaust and cooling head as necessary, drain fluids, and unbolt the rear cover in the recommended order. Clean the mating faces of gasket material before fitting the new plate and torque fasteners to the service values. After fitting, check bearing seating and shaft endplay to ensure correct assembly.

This item is meant for maintenance and rebuild operations rather than tuning; it restores original fitment and helps maintain consistent engine performance during service intervals. Keep the component free of abrasive material and inspect the sealing surface at regular servicing.

A straightforward replacement for KE21V rebuilds, the Kyosho 74035-07 back plate restores sealing and alignment for dependable engine behaviour in model applications.
