Sliding tandems

FWIW, tandem slider holes are 6" apart. Depending on which states you run, you may have a kingpin-distance limit, which will take precedence; CA limits to 40' (the second hole from the front, the first being 39'6" for ID off-highway), PA is a 41' state (4th hole), NY is a 42' state (6th hole), etc.

MOST of the time, I would just pace-off the distance I needed to slide (from where I was to where I needed to be), walked up to the cab, scored a line in the dirt right next to my set, then paced off the distance and scored of the second line, then just pulled the truck up that exact amount.

As far as those little stoppers on the sliders, yeah, it'll get REAL old quickly in the winter, having to crawl under a dripping trailer with a hammer to get the d@mn things off. Let's hope you never take a dirt road on a rainy day, either! But, hey, it's your money, and it's your choice to spend it foolishly. I've seen people waste literally THOUSANDS at chrome shops....

 

Good "rule of thumb", which usually works, provided your load is reasonably centered. I used to have loaders at a place where they would block a group of 3 9000lb cardboard reels which sat flat on my trailer floor (with 2 right up in the nose). I knew that my load was going to take me through PA, so I set my tandems in hole #4, pulled out my scientific calculator, and just calculated where the weight centers should be for an evenly-distributed load. Ended up a nearly-perfect 33000 each axle set.....

 

It gets wedged against the chassis.

 

sure I used to use it all the time

 

Chalk or walk

 

Just slide it until my 5th wheel guage reads 33400. On the rare occasion I'm hauling anything over 35K.

 

Oh, so you have to climb under each slider TWICE each time you make a slide (once to put them in, and once to remove them)? And this is an "improvement" in just what universe???? Again, you aren't making sense....

 

Once again a poster not really looking for advice but more affirmation to something he doesn't understand in the first place.
We've all told him how to do it, yet he insists that he has all the answers.
That's fine.
