The New Rover Cycle Co., Ltd.. Coventry.
The Rover lightweight is numbered among the chief attractions of the Show, and its novel power unit is separately staged for the admiration of enthusiasts. This unit comprises engine, oil sump, gear box, kick-starter, clutch, and magneto, built up in a common assembly. The engine has overhead valves operated by roller bearing rocker shafts, and the detachable head is fixed by three studs. The primary drive is triangular, the chain passing over the magneto sprocket. In order to withstand the pull of the drive, a specially strengthened armature shaft is incorporated in the M-L Maglita. The chain is adjusted by bodily moving the magneto. The gudgeon pin bush is the only plain bearing in the unit. Lubrication is by splash, an oscillating plunger pump being used to raise oil from the sump into the crank case. An external lever adjusts the delivery aperture of this pump. Very attractive features of the machine are the B. and D. shock absorbers on the front fork, the new saddle tank, and the spring-up back stand.
