The Star 660 is a Polish 6x6 truck designed for transport of cargo and personnel. Created by Starachowice-based FSC Star, it was the basic transport truck used by the Polish People's Army.
History
This model is a modernization of the Star 66 truck produced since 1958. As a result of the experience gathered and the army's comments on the operation of the 66 model, it was decided to modernize and better adapt this vehicle to perform the tasks it was assigned. Design work on the modernized model began in the early 1960s at the Automotive Industry Design Office in Warsaw and the FSC Star Design Office. The effects of the design offices' work were presented in 1962. Due to the lack of technical and financial capabilities of the Starachowice plant, it was decided to carry out the process of implementing new design solutions in two stages.
Production of the modernized model, designated Star 660M1, began in 1965. The vehicle body was mounted on a welded longitudinal frame made of pressed sheet metal. The chassis featured a front rigid drive axle suspended on semi-elliptical leaf springs and two hydraulic arm shock absorbers. The suspension of the middle and rear axles consisted of drive axles, each suspended on two inverted semi-elliptical leaf springs and six reaction rods. The drive axles were equipped with a pneumatically controlled differential lock. The braking system was adapted to supply the trailer brakes and was equipped with an overpressure power steering system. The Star 660M1 was powered by a Polish, 6-cylinder, in-line petrol engine type S47, with a displacement of 4680 cm³ and a maximum power of 77.3 kW (105 HP). The drive unit was locked with a 5-speed manual, non-synchronised gearbox, connected via a tubular shaft with a mechanically controlled two-speed reducer. Additionally, the gearbox was integrated with a power take-off enabling the transfer of power to external devices. The Star 660M1 was equipped with an open, two-person N66-type wagon cabin with a tarpaulin roof that folded backwards and a two-part windscreen.
In 1968, this model was modernized. The modernized vehicle, designated Star 660M2, used a metal-tarpaulin roof structure for the cabin, improving thermal and acoustic insulation, and the shape of the engine cover and gear shift lever were changed. The changes also affected the vehicle's electrical installation by shielding it, adapting it to work when completely flooded, so that the vehicle could overcome deeper water obstacles and be dragged along the bottom. The braking system was equipped with an increased power steering pump capacity and a trailer braking system control valve.
In the same year, the Star 660D model was introduced into production. This version was powered by a 6-cylinder, in-line diesel engine of the S530A type, with a displacement of 6230 cm³ and a maximum power of 73.6 kW (100 HP). From 1970, a more powerful diesel engine of the S359 type with direct fuel injection with a displacement of 6840 cm³ and a power of 110 kW (150 HP) was also used.
Despite the introduction of the new off-road truck Star 266 into production in 1973, production of models of the Star 660 family continued until 1983.
On the chassis of the Star 660 model and its derivatives, various versions of superstructures were mounted, such as the GBM 2/8 (firetruck), 117 AUM type van body, the Hydros R-061 or ŻSH-6S truck crane, the K-407B excavators, the R-118, R-137 and R-140 radio stations, the R-404 and R-405 radio link stations, the 750 Sarna type repair bodies, the AP-64 type bodies for transporting pontoon blocks, the BP-64 type bodies for transporting coastal blocks of pontoon parks or the SMT-1 accompanying bridge.
A total of 13,760 Star 660 vehicles were delivered to the Polish Army.
Post-production development
In 2000, the modernization of the Star 660 was proposed by the AMZ Głowno company, as a result of which about 100 trucks of the Polish Army were rebuilt by various entities to the Star 660M3P version. Its main element was the replacement of the engine with a modern IVECO 8140SRC20 turbodiesel with a capacity of 2.8 l, maximum power of 122 HP (90 kW) and maximum torque of 285 Nm. In addition, a ZF steering gear with hydraulic power steering, a dual-circuit braking system with power steering and a 24 V electrical installation were used. Despite the use of a moderately powerful engine from an Iveco Daily delivery van, this modernization improved the vehicle's parameters. Subsequently, approximately 20 vehicles were modernised to the Star 660M3 variant by WZM in Siemianowice Śląskie, which fitted an IVECO engine with a maximum power of 170 HP (125 kW) and a maximum torque of 550 Nm.
