Double Clutching

Its a matter of preference really. most guys prefer floating but I double clutch myself. If you master it then you wont hurt your truck. At first I was doing it as a twisted form of getting some excersize, but now its just automatic.

 

You've got to match your engine speed to the road speed for the gear you're trying to go into, whether you use the clutch or not....so why use it?

 

double clutching is more work but your transmission # clutch will last longer.

 

I am in cdl school, and they are teaching us to double clutch. My first day I picked it up pretty quick(and still grind the gears quite a bit) but when the instructor isn't looking(he is on his phone a lot) I just float em and no grinding at all. He looks over and says "now you are getting it!" and goes about his phone conversation, LOL.

 

The only reason I see to double-clutch is that some companies may require it on their road test.

I failed a road test years ago because I couldn't do it. Now I stay in practice but generally float gears.

 

Big John is right that companies want you to be ABLE to double clutch. It is a good idea to know HOW to do also. You may need to use it someday, say if you miss a gear pulling a steep grade, or worse, going DOWN a grade. That said, I almost always float, but occasionally clutch to stay in practice.

 

Grind then till you find em Im still a noob but the last time I double clutched was when I took my CDL test. Didnt need to double clutch since then, sometimes I use the clutch to get out of gear but then I float to get back into one.

 

It depends on the weather, terrain, and weight of the load. If I'm hauling LTL, I'm virtually always floating. But if I'm hauling 40,000 LBS + of cargo, I'm virtually always double-clutching. Slick roads are another good reason to double-clutch.

 

Not a bad idea to know how to double-clutch, certain weather conditions and grades you will need too? Either way matching rpm,s and speed along with some feel for the truck is key for both, wether you are up-shifting or down-shifting, it is all about the rpm's. I do both depends on were I am.
