ENGINE TESTING DEPARTMENT This department lies adjacent to the engine assembly

section from where the assembled engines are send on roller conveyor to this department for testing under loaded conditions.

There are a number of testing beds in this section for carrying out the test. Each of the test beds has individual control rooms for monitoring engine performance.

The test beds are made sound proof from inside to reduce noise pollution. Also there is provision for discharge of emission of the engine into the atmosphere so to prevent pollution inside the section.

Each of the test beds are interconnected and are facilitated by electric overhead cranes for mounting and unmounting the engines onto the test bench as and when required.

The engines tested and passed from this section are taken directly to the Tractor Assembly Section for final assembly to the Chassis.

As the name suggests this is the final place of assembly of complete tractor. The tested engine from the engine assembly, differential, gear box, front wheel assembly, steering mechanism, clutch assembly, brakes etc. are completely assembled here to form a complete chassis of the tractor followed by painting and final fitment of the external metallic body, other accessories and wheels to complete the assembly. The assembly of chassis is carried out while it being suspended from a continuous overhead conveyor system.

The differential as well as the complete gear box is assembled here and later on sent to the final assembly line of the tractor assembly. The complete chassis is formed here, followed by passing it through the painting and drying sections lying in between the assembly line.
