T"year 1925 saw the introduction of the first Leyland Lion bus chassis, and since that time this model has been giving excellent service to a very large number of users.
For 1929 the Lion has been redesigned to bring it into line with the new Leyland range of passenger chassis of the six-cylinder type, but the engine will still have four cylinders The unit, however, is built on exactly the same lines as the six-cylindered engine, in other respects also the chassis is built on the lines of the six-cylinder models. This has enabled many of the parts in the Lion to be made interchangeable with those on the other chassis. For instance, the latest type gearbox, with its cover carrying the selector mechanism mounted at the side of the box instead of the top, is bolted up as a unit with the engine and clutch. The change-speed-lever box is carried at the off side of the crankcase, and use is made of the remarkably smoothacting, toggle-or.:Tated single-plate clutch with fabrie-aced clutch stop.
A two-piece propeller shaft with Spicer-type joints conveys the power to the underneath worm of the rear axle, which provides alternative gear ratios of 5.5 to 1 and 6.5 to 1, according to the requirements of the buyer, the higher ratio being found to be more satisfactory, except where the condi
tions of usage are particularly arduous.
The frame is of deep channel-section steel braced with robust channelsection cross-members. Long semielliptic springs of chrome vanadium steel, practically flat under load, are utilized for both axles, and, as in the other recently produced models, wear on the sides of the springs, frame brackets and shackles can be taken up by a screw adjustment.
Lubrication is effected by batteries of Tecalemit ,nipples arranged in acces sible positions, and the whole chassis can be attended to in this respect in a few minutes.
A 35-gallon petrol tank with an arrangement for a• reserve supply is mounted at the near side of the chassis frame. Light steering is afforded by a Marles cam-and-roller gear.
• Braking is effected through a Dewandre vacuum servo.
