Double clutch question

[Deus]

When I learned how to drive truck I was taught to double clutch, of course now I float but every now and then I still double clutch a bit just so I don't forget how to do it, just in case :-)

Floating gears is just about mandatory if you run a dump truck. You shift hundreds of times a day, your knee would be wore out if you double clutched all those shifts.

bikerboy, I know exactly what you mean. I used to drive concrete mixer trucks (Mack 8spd) all the constant use of the clutch. especially when pouring into curb machines was hell on my knee. Mechanics told me to float the gears to save on the clutch cables(broke it twice).

I know this is a four-wheeler (a Beemer at that). But it does show the double clutch technique. I hope this helps.

Double clutching is one of the things that they grade you on in CA. However, that alone own't fail you, but it lowers you score.

u can fake it

I thought that was case as well. Just push the clutch two times while shifting normally.

Before CDL training, I had never operated a manual transmission before in my life. I got pretty good at double clutching, but I can see how that would become exhausting, especially during local, in town runs.

When I rode with a guy at Swift, he never touched the clutch except to put it into low gear or out of low gear. If I had driven like the guy who took us to the CDL test, I would have failed. LOL

Double clutching is actually a better way to drive. Without it the only way you can pull it out of gear is by quickly unloading the engine. When you think about this, you're actually using extra fuel.

u can fake it i just push once put foot on clutch and float it they can't tell it

That's funny that you say that...the first instructor I had for double clutching actually took the oil out of the clutch so that he could hear the clutch squeak twice to make sure we were double clutching

That is about the dumbest thing I've ever heard.

Well I gave floating the gears a whirl this weekend. It does save on the left leg (I am a local driver). Some of the gears are easier than others (to float), but I still have to single clutch in some circumstances. I don't have the RPM match down pat yet.

Conway and Roadway required you to double clutch during the road test.

Your best bet is to use the clutch regardless. If you can know that you can change gears better by floating in a certain situation, then you will figure out a way to make it look like you are using the clutch.

That can also come from the gears being ground too much. Alot has to do with previous drivers of that truck.

I think in reality double clutching is less safe. More you have to concentrate on, plus I'm a local driver and as such I'm in and out of the tractor all day long. When it is wet ouside, I find it is pretty easy for your foot to slip off the clutch. Plus when you're on a bumpy road, it can be a real bitch.
