In sheet metal painting for various applications like tractor and automobiles, most attractive coating is metallic paints. It is widely applied using 3 coat 2 bake or 3 coat 1 bake technology. Both options, results in high energy consumption, higher production through put time and lower productivity in manufacturing process. During various brainstorming and sustainability initiatives, paint application process was identified to reduce burden on environment and save energy. Various other industry benchmarking and field performance requirement studies helped to identify critical quality parameters. There was collaboration with supplier to develop monocoat system without compromising any performance and aesthetic properties. This resulted in achieving better productivity, elimination of two paint layers, substantial reduction in volatile organic content, elimination of one baking cycle and energy saving.

Innovative setting bracket design to improve the tractor Fit and Finish between the Bonnet and Custer panel (Scuttle) The paper presents an integrated approach for arriving a process to assemble scuttle regarding bonnet to achieve Gap and flushness aesthetic requirement. Variation is inevitable due to fitting of bonnet on Tractor front semi-chassis, scuttle fitting on tractor middle clutch housing and assembling many parts with different tolerances, hence the deviation (stack-up) obtained after their assembly varies from approximately -10.175 to 9.775 mm. This is quite large and gives a huge impact in aesthetic point of view. To overcome this issue, we introduced one Innovative intermediate bracket as the setting gauge which is assembled with reference to bonnet and scuttle is mounted on this setting bracket hence zero flushness and uniform achieved between bonnet and scuttle.

The tractor usage is growing in the world due to derivative of rural economy and farming process. It needed wide range of implements based on the applications of the customer. The tractor plays a major role in Agricultural and Construction applications. In a tractor, hydraulic system is act as a heart of the vehicle which controls the draft and position of the implement. Hydraulic system consists of Powertrain assembly, 3-point linkage and DC sensing assembly. The design of hydraulic powertrain assembly is challenging because the loads acting on the system varies based on the type of implement, type of crop, stage of farming and soil conditions etc., Hydraulic powertrain assembly is designed based on standards like IS 12207-2019 which regulates the test methods for the system based on the lift capacity of the tractor. In this paper, virtual simulation has been established to optimize the design and perform the test correlation.
