can you also specify the dimensions of the shaft which you are using and get sheared and also the coupling after output shaft.vikram singh tI'm making an off road vehicle with Engine of Cummins 4BT, 1800 rpm, torque 269 pound-feet with portal axle gear box. Meanwhile i have increased the rpm to 3000 and also ratio maintained in portal gear is 1:2.

The input shaft dia 32 after reduction( ration of 2:1)the output shaft dia is also maintained same.Consider the ratio as 2:1 instead of 1:2 as mentioned earlier.there is no coupling .Shaft will rotate hub to which wheel rim is fitted.Anku2993can you also specify the dimensions of the shaft which you are using and get sheared and also the coupling after output shaft.

Ok dear, i got your situation. One more thing i want to know in order to check the shaft whether it is correct or not.vikram singh tit is off road vehicle, the total weight of the vehicle is 2.5 ton & shaft material is EN353,
As you said 1500 RPM will be required when we are driving against the steep roads(uneven terrain ).
