Truck, 1/4 ton, CT, 4x4, Cargo, FFW, Austin Mk.1, FV1801A/1802A (Champ) B40 No.1 Mk 2A Engine, Whittlesey.
The Rolls-Royce B40 Engine fitted to the Austin Champ was based on a 1936 Rolls-Royce design that had been created with absolute reliability in mind, the pre-production and early production Austin Champs were fitted with the same Engine as the 'Mudlarks' the B40 No.1 Mk 2A using the BSF (British Standard Fine) thread system on studs, bolts and nuts etc.
These were crossflow inlet over exhaust in-line four cylinder engines with a capacity of 2,838cc and featured a cast aluminum cylinder head with screwed in hardened steel valve seats. This would change after the 1949 standardization to UNF (Unified Fine) threads for later production Austin Champs to use the UNF thread engine B40 No.1 Mk 5A [UNF]. This engine featured some manufacturing simplifications, used a cast iron cylinder head, and was painted light blue with “UNF” cast into its rocker cover.
Early production engines were manufactured by Rolls-Royce at their Crewe factory but most Austin Champs were fitted with the later Austin manufactured engines made to the Rolls-Royce designs. The engine drew its fuel from a 20 Imperial gallon fuel tank. Fuel consumption was expected to be around 15mpg giving a range of 300 miles, although if being driven enthusiastically fuel consumption would drop into single digits and the vehicle range would be somewhat shorter.
The engine, transmission and electrical system were all waterproofed so the vehicle could operate submerged to a depth of six feet. The air intake featured a folding snorkel that could be raised if the Champ needed to do a water crossing.
