First off, let's find out what makes the RCV 58 CD tick. The crankcase splits horizontally about its thrust line, with the upper and lower cases being held together by six Allen bolts. Removal of the bolts and gently separating the cases reveals the intricate innovative workings of the RCV. Our next job is to gently lift out the crankshaft along with bearings, thrust washer/seals, prop driver, piston and conrod assembly; all can be removed in one go.

At last, a single cylinder four-stroke of over 120-size. . . at a decent price, too.

Let’s start the strip in the usual place, by removing the pressure die cast alloy backplate. This has bright machine-finished internal and external mounting flange surfaces and, cast into its centre, is its new country of origin - ‘China’. With an internal flat at the top for liner / piston clearance, the backplate sits deeply in the crankcase and is fastened by four M4 Allen bolts. Sealing is by a rubber ‘O’ ring that’s fitted in a machined-in groove just inside the retaining flange.
