This paper presents the design of the spur gear on different geometric condition and finding of the effect of these on tooth load by changing the module and face width. 3C diesel engine, which has the power rating 69 kW at 4200 rpm is used as the engine of Light Truck. In this gear box, the forward speed gears are helical type whereas reverse speed gears are spur type. In an automobile gear box, the reverse speed gears have a minimum speed of revolution that means maximum torque will be exerted. So in this paper, the design of spur gear for 3C diesel engine is described. The selected material for in the spur gear pair is AISI 5160 OQT-400 Alloy Steel. Tooth load is calculated with help of Lewis equation. Dynamic tooth load and wear tooth load are calculated with help of Buckingharm equation.
