Benefit of double clutching

Double clutching is for non-synchromesh transmissions.

 

Simply put, big truck transmissions are not synchronized. Double clutching matches the main shaft speed of the transmission to the engine speed/rpm.&nbsp;<br><br>On upshifts, clutch in, shifter to neutral, clutch out, clutch in shifter to next gear, clutch out. Timing is every thing, match rpm to road speed. &nbsp;Sounds funny, but think of the adams family theme song to get the perfect timing. The whole shift should take place during the duh-duh part of the song lol.<br><br>Downshifting, clutch, shifter to neutral, throttle up/ clutch, next gear. Much easier, just have to match the road speed to the proper gear, and learn to be quick.<br><br>Any help?

 

Sunshine it's supposedly is supposed to make taking it in and out of gear easier. It "saves" the transmission by not chewing up gears. But I've found its harder on the trucks by creating lash in the drive line. Clutching out may help but clutching in doesn't do much to be honest. Plus you will burn up a clutch pretty quick if your not fairly good at it. If your new to gear grabbing I say go ahead and by all means do it. But if your getting a little time under your belt then ease yourself into floating the gears. May be rough at first but worth it in the long run. Ps don't tell anyone about this. I'm a trainer for the same company. Lol

 

It makes your left leg much larger than your right so you walk in a circle.

 

Clutches ... We don't need no stinking clutches... Double clutching is how you are to learn shifting a non synch transmission. Once mastered you may be able to start floating. As long as it's done with out grinding ! Grinding is not good no matter the shifting method ! Have had trainees ask if my truck was a auto ? Made me laugh, "you see me shifting" !

 

double clutched with a set of sticks but quite when i went on a single stick truck. to me its just something to do if you are bored. with the ease of driving these new trucks you dont really need to do it. i know a lot of young drivers are going to rear back and say they do it all the time but i was driving before some of them were even born, so by now should know a little bit about shifting and clutching a truck and like sdanial said grinding is bad. be safe out there

 

You get into any kind of serious construction sitework driving, you'll learn the benefit of it quick. You'll hit a good number of access 'roads' or running over bare earth where the only way to not get stuck is not to stop. Hitting soft spots where you have to suddenly drop several gears quickly, you won't accomplish by floating - least of all, while you've got the power divider and differential locks engaged.
