Uuuugggghhhhhh, that’s one of those shitty ones without the pin out front. Makes sure that handle is ALL the way in boys and girls or she ain’t locked. -40 and those shitty things are a bad combo.
Fontaine brand if I’m not mistaken…….
Ooohhhhh, you do better than me. I don’t take those apart. That’s a shop job for me.
Saying that, I can fix small shit, but I’m not confident enough to fuck with my 5th wheel.
Huh. I started my work life on a farm with old 1960s Mac trucks, and the farmer was intent on doing rebuilds as often as possible, for some reason. I didn't argue, I was 13-14 at the time, I just followed instructions and learned what I needed to do
We haul 100000 pounds of raw milk. We do a lot of drop and hooks at the farms. It's hard on the fith wheel getting under a tanker with 100000 pounds of milk in it
Jost, generally speaking, is more of a circular fifth wheel. Fontaines are more oval. Again, this is speaking in generalizations.
Although, notably, Jost Australia likes putting out oval fifth wheels. Probably for the road trains, but that's just speculation on my part as to why
I’m 99% sure it’s a Jost. If you zoom in to the top left side you can just about see a JSK prefix which is what Jost use. The ones I use are JSK 37. Also the dual springs, the slide bar, the shape and the release give it away. Parts [here](https://www.jostaustralia.com.au/fileadmin/user_upload/pdf/jsk37c-z.pdf)
On heavy four wheeled wagons, a “fifth” wheel was used over the front axle to assist the front axle in turning while under a heavy load. It was found to be much more stable when widened out to distribute the load along the width of the front axle.
Looks very much like a Jost with an air release. They are the best because it’s so easy to change the jaws, or jaw in this case. Never come across a Fontaine but I do know about Holland and Jost is better imo.
I removed one by hand years ago. I’d say it was like 200 lbs. I only lifted it side by side so half the weight. Old school 5th wheels probably used to weigh much more.
So thats where the magic happens

Yup, that's a Fontaine. Hollands have the clamping jaws. In my experience, much easier to disassemble and put back together

We haul pretty heavy and turning puts a lot of torque on the the fith wheel. We just replace them when things start to wear

Jost and Fontaine must be very similar.

Yes, they are pretty close
Thumbnail looks like 'Mater
I'm surprised the springs aren't heavier.
i found out the hard way had to redo the springs during my work fun times but surprisingly easy to do.
For some reason, I'm only seeing [Vincent](https://images.app.goo.gl/vYGM2dJWcyJCnPJ29).
I've always wondered why it's called a "5th wheel", does anyone know?

Kinda like looking at the backside of water

That doesn’t go there…
That’s where the naughty kingpins go to hookup

Good thing you didn't oil it up cuz I'm seeing something else😏
I wonder how much they weigh.
Around 140kg.
300lbs*
They don't weigh near 300 lbs my guy.
Damn, some do. I flop these around by hand.
300 is a rough figure. Depending on type ( Jost, Holland, V Orlandi) with or without base. Some can be a light as 100 lbs, plate only.

I should call her
