Non Moving bolted 5th wheel?

You would need to just buy a Fifth Wheel Frame with the Slider, you can reuse the same Fifth Wheel Top Plate.

You would need to check what Make your Fifth Wheel is and contact a Distributor and get a quote on what one would cost.

Most Freightliner trucks are equipped with Fontaine or Holland Fifth Wheels.

You would also need to run a air line from the fifth wheel to a switch in the instrument panel.

Most likely your truck already has the air line installed from the factory, so you would need to buy the Switch.

I would estimate the cost with parts and labor could be around $1800 to $2500.

Another less expensive option would be to purchase one from a salvage yard.

Some fixed Fifth Wheels can be moved, but you will need to unbolt it and move it back towards the rear of the truck.

 

How much are you overweight?

 

I agree with everything boneebone said. I just want to emphasize to identify exactly what 5th wheel you have. Every brand makes several models, so knowing the brand might not be enough info to order the correct slider. Most 5th wheel manufacturers also make top plates for replacements for their competitors, this can add to the confusion if you do not know if it's original or not. This is why it's important to know the exact model/part #.

 

What are your axle weights in a scenario you described OP?

 

Just unbolt it and slide it back. Any shop can do that.

Its all just a matter of leverage. Once you find the sweet spot where you've maxed out your drives and steer at the same time, leave it alone.

 

Exactly. Get your axle weights on a few different loads to give the shop an idea how far it needs to be moved. Once it is bolted down where it needs to be for proper weight distribution (should be 12K +/- 100# or so when the drives are @ 34K full of fuel), you shouldn't ever have to slide it...so there really isn't any need to spend a ton of money correcting an issue that could be solved in about 20 minutes for nothing but the labor.

 

I believe that's called a stationary 5th wheel.If you're no more 500 lbs over the DOT won't say anything.Can't you just move the tandems to even the weight?Or tell the shipper to not load it all at the nose of trailer.
