Surge Control Help

Either that or pretend there is an egg under your fuel foot and push easy.......ease the power on. This is an acquired skill..........

Lemme make you feel better....when I first broke out in tank.....I was all that...yep, I had it down. Well I rocket up to a stop light like a freight hauler ...and stopped.

Yep, all that. The surge hit me so hard i set the brakes and went back to see what hit me. That car had to be totaled...... but there was no car......nothing there but my embarrassment.

Good luck driver....

 

When you accelerate, as you are accelerating, the product will go to the back of the trailer When you get ready to shift to the next gear, accelerate up to the speed and hold it there. Then gently take your foot off the throttle so as not to decelerate too quickly. This will keep the product at the rear of the trailer..then shift smoothly into the next gear, say you took it out at 1800 rpm, put it in 1400 rpm, hold it there at 1400, wait until you feel the product bump the rear of the trailer, then you accelerate...gently
The big mistake most people make is they try to shift like a normal truck..you have to have a delay between when you getit in gear and when you get on the throttle. You have to wait for that little tug, then accelerate gently... Hesitate, wait for the little bump or you will get the slam.

 

Ok..when you shift you going to lose road speed. The truck slows down, the product does not. So the product will slosh forward a little but then gravity will take over and the load will go to the back of the trailer. If you accelerate too fast, you are slamming the back of the trailer into the product. If you wait to feel the "tug" signaling the product has flowed back then accelerate gently you don't get the slam. It is keeping the product and truck in syncronized speed.
(never explained this in words before, easier done than said)

 

It was e z to teach 'em using a 5 speed R Model Mack...

Complete the shift and let the clutch up and wait some b/4 hitting the throttle.

Once the clutch is up the drive line is pulling and the wave starts back.

Smooth is how soon you gingerly turn on the power...

The old timers said get it in the back & keep it there!

 

A continuously-variable transmission would be a godsend to trucking, and particularly to tanker yankers.

 

or a twin clutch like the new i-shift2, there is no break in power from start to top speed.

 

If you are pulling a slight grade, once you have shifted and your foot is off the clutch, hold the road speed/rpm. Keep it steady. Don't let it fall off. You may be easing into the throttle just to maintain the road speed/rpm, but give it just enough throttle to maintain that road speed/rpm. You will feel a little tug because every time you shift, the product is going to come forward a little bit and then go back. It will be less of a tug on a slight grade but you can feel it. It feels like a slight touch of the trailer brakes.
After you feel the tug, then you can get on the throttle to increase road speed/rpm.

 

Sounds like catching a wave when bodyboarding.... catch it just at the top, paddle like heck and flow with the wave! <G>
Hope y'all are having a good day!
