Tryen to start a load moving on a semi with out the clutch can be done BUT do you really want to as if things go wrong your piggy back will not like the end results . And you say ah what can go wrong ??? lets look at what all can go wrong , shearing of all the bolts holding the transmission to the bell housing , Ripping the centers out of the clutch , twisting the drive shaft , breaking the u/ joints.ripping the gears out of the power divider , tearing up of the ring gear , twisting and axle , ripping the engine mounts off the frame , breaking the bell housing . You can still do all this damage even usen the clutch . But once you LEARN HOW TO DRIVE a big truck shifting one up and down with out the clutch becomes second nature and you will never grind a tooth and each shift is as smooth as silk . When first starting a load with a semi you normally do not even have to push on the fuel pedal as the Governor will pick the load up and once the clutch is fully engaged then you add power . Only two times did i ever have to add power to get a load moving , First time was with my brand new 1977 4300 as that was the first year for the ceramic disc clutches and those clutches grabbed hard till they got seated in . First load i put on her back every time you went to take off she would grab hard as there was no feathering it was either in or out even at ideal . I had a fortyfive ton load on and i was tryen to get it to come off a light on a hill and each time i came up easy on the clutch she would grab and kill the engine . OK enough of this you are either going to learn how to engage or i'll ripe you out here and now . stuffed her in third gear put the go pedal on the floor and came off the clutch and Crowler slid her out in third , that trimed the rough edges off that clutch and was smooth as silk after that . then the second time was getting 389880 lbs moving .
