The first two trucks I drove had beveled gears and you didn't need to double clutch or even use the clutch at all.Good Tractor Morning,
Mostly, Square Gears, is just another way to say the truck shifts with difficultyBill was a professional truck driver , me, I’m a converted toolmaker/ model maker , who after almost 40 years working inside that I was going to be a truck driver. I was referring to a Mack Cab Over that could not be reved, you had to shift at low rpm and double clutch, although Bill could probably do it without even shifting.
I remember training on that truck and the guy riding with me telling me that it’s going to be a long day if you can’t get the truck into the next gear !![]()
Then I got an International with no beveled gears and you were supposed to double clutch. BUT if you got the engine rpm and the transmission rpm within 100 rpm of each other the gears would drop in, no clutch needed. If you missed a shift, then you would stop and start over. When you got tired of starting over then you learned. The second one was a 'single axle' (meaning single drive axle), the first one was an imitation tandem (single axle drive but tandem axles the second axle was an air-lift axle and didn't drive, a real P.I.T.A. in the snow). 5X4 transmissions are usually "married' meaning you didn't go anywhere unless both transmissions were in a gear. They are fun to shift without the clutch, but I got good at it and taught it to all the people I trained. I ONLY taught people who already had a license could handle the truck (given its size), just couldn't get a handle on the transmissions and how the two worked together to get on down the road.
