The Bedford TK is a larger foward control truck that was produced by the Vauxhall Motors-owned Bedford Vehicles company. Launched in 1959 to replace the Bedford S type, the TK was scheduled to be replaced by the Bedford TL in 1981, but manufacturing of the TK continued as a cheaper alternative.
TK series as KA, KG and so on. Depending on their tonnage and years, these vehicles, in Diesel version, are equipped with 4-cylinder engines of 3.29 and 3.60 liters (200 and 220 cu in) or 6-cylinder engines of 4.93 and 5.41 liters (300 and 330 cu in).
In the advanced cabin version (TK series) with engine at the rear of the cabin which allows 3 seats in the front as in a normal cabin, these vehicles exist in as many as twenty different model versions in the chassis cab series., available as platform or tipper, tractor as well as the 4 x 4 version. "
A military 4x4 version called the Bedford MK was also produced. After Bedford's Dunstable factory was sold in 1987 to AWD, the TK restarted production for military only use until 1992 when AWD went into receivership.
History and use
The TK range replaced the S type in 1959, and served as the basis for a variety of derivatives, including fire engines, military, horse boxes, tippers, flatbed trucks, and other specialist utilities. A General Post Office (later British Telecom) version used for installing telegraph poles was known as the "Polecat".

Available with an inline four or inline six cylinder petrol and diesel engines - the TK was the quintessential light truck in the UK through most of the 1960s and 1970s, competing with the similar Ford D series. It was available in rigid form, and also as a light tractor unit normally using the Scammell coupling form of semi-trailer attachment.
An unusual variation on the well-known TK range (which covers payloads of 3.50 to 11.40 tons) is the TK 1260 Twin Steer model specially developed to keep axle loadings legal under variable delivery conditions. Small wheels also reduce loading height.
It has a 14.730 kg (14.5 ton) GVW, 5 forward gears and six-cylinder 81 98 cc (500.3 cu in.) diesel engine developing 94.3 kW (126.5 bhp) net.
In 1981 Bedford introduced turbocharging to the "Red Series" 3.6-litre and 5.4-litre diesel engines, now producing 72 bhp and 102 bhp respectively.
