I'm going to try to replace my kingpins today. Has any tried sticking the kingpins in the freezer for a few hours before torquing them? I've read where some guys heated the inner C, then torqued. Figured this should work about the same.

Freezing kingpins

This could show my ignorance but... Why would you heat or freeze it to put it together? It's not an interference fit so it screws right in. I can see heating the knuckle to get a stuck king pin out but not putting it together. If anything wouldn't this potentially allow the king pin to be torqued too much because of the loose fit while tightening?
You probably have more experience than I do with this. I'm just thinking that cranking down on a cheater bar isn't going to get me anywhere close to the 600 ft/lbs. My 1/2" breaker bar is only rated to like 200ft/lb or so, so even if I actually break the breaker bar then I'm still not even halfway there.
if you have any tire shops around that do big truck tires they might help you out with the wrench this big.
i just click it at 600ft lb with my 3/4 drive wrench .

Really, only 200 ft/lbs? I put a 6 ft pipe on my 1/2" breaker and it supported my almost 200 lbs which would be about 1000 ft/lbs. It did break when I jumped on it but Sears replaced it free when their program still allowed it though.

It's a ratchet
Going to check out a 3/4" breaker doubt I can break that.

Thought you said breaker bar.

Haha! It's a ratcheting breaker bar, still not as strong.
So no one has had any problems with just going to town on a breaker/cheater bar? I'm just paranoid I won't get them right enough.
I took some out of 79 HP60 with an Allen wrench and aluminum tube while the axle was stripped laying i the floor. Came out pretty easy, tightened the same way. Zero issues.
The bolts that hold the blades on my Brown bush-hog type mower are supposed to be torqued to 700-800 ft/lbs. I use one of these with a 10 foot long piece of water pipe.

I put a digital pull scale on the end of the pipe, and pull about 75lbs. So far no breakage and no loose blades.
Of course, just the bar is not enough. I had to buy a one inch drive socket and extension.
All told, I had about $140 in the system, but considering the damage a blade could do it if came off, or just the cost of replacing the parts if it ran loose for a while, its cheap.
Plus, unlike doing the kingpins, I use the system two or three times per summer.

Yep, broke the breaker bar. Managed to get one off though.

I haven't had the pleasure of removing one of these however I would think some heat would be beneficial.

Can get 1000 lbs with a 1/2" dive and 12000 Lbs with a 1" drive.
I bought a 8' piece of hex stock bent the end to make a hex key.

Got'em! Damn that was an all day affair. Broke 2 1/2" breaker bars, one 3/4-1/2 impact adapter and just a little bit of pride.
And I'm the proud new owner of a 3/4" breaker and one socket

I just hope to catch mine before the pins are damaged.
judging by your avatar pic that's not going to happen .
Use a 7/8 lug nut. One of the 2" long ones. A 7/8 wrench and a four foot extension bar. I broke em loose and installed em with a kobalt brand wrench and checked the torque applied to be curious. Clicked at 600. I know it's good.
So I did leave the kingpins in the freezer until it was time to put them in. Then used my impact with max torque rating of 450ft/lb. Then once they warmed back up I gave them a good tug both ways with the breaker and 4' cheater, just to check. I seriously doubt they are over torqued.
Looks like autozone has a torque multiplier to rent so I may get that one day to make sure they're good.
