M type

 Fitted with a Meadows 4ED engine, usually with a single Solex carburettor, the M-Type was significantly quicker than the J and K-Types with their 4EC and 4EB engines, but the additional power put significant strain on the transmission, often leading to failure, particularly of the rear axle.

Designed in late 1925, the 1926 Lea-Francis range saw a number of modifications being made to the chassis design. The newly designated J, K, L, M and N types kept the quarter elliptic rear springs, hand-brake operating on the transmission and cone clutch of the earlier models, but with improvements such as stiffer rear cross-members and improved rear spring mounting. All models, except the G Type, now came with four wheel brakes as standard.

When fitted with the then new, higher revving Meadows 4ED engine, motor cars on this chassis were designated L or M type. The 4ED engine featured a separate aluminium crankcase and a pressure fed crankshaft mounted on three white-metalled main bearings. This with alloy connecting rods and larger ports in the cylinder head and a reasonable camshaft profile gave a more powerful and easier revving engine than the 4EB and 4EC types. In fact, while arguably a little too powerful for some of the components on the earlier Lea-Francis cars to which it was fitted, the Meadows 4ED became the engine of choice for the majority of the company’s cars from this point on.

 The M-Type was equipped with Hartford shock absorbers on the front only and many had Dewandre brake servos. Most were two-seater or four-seater tourers or saloons.

236 M types were built of which possibly six have survived, four owned by Club members.
