How did you all torque your kingpins?

    best thing I think I have ever heard was, heat the knuckle up, put some lock-tite on the threads, then just tighten the kingpin with a breaker bar. When the knuckle cools, it will contract onto the kingpin and tighten up.

    I used a 7/8 allen key and a section of my rollcage around 5 feet long. Just keep your tourque in mind when you use a large bar. Try to judge how much force youre putting on it.

    We used to use a 4X multiplier with a 4 foot long 3/4" drive torque wrench to do U-bolts to 600 ft/lbs. It was basically a small planetary reduction drive that went between the torque wrench and the socket.

    A 6 foot pipe on a 3/4 drive breaker bar would be eaiser though although you'd still need 100 lbs of pull on the end of it.

    I walk into my garage and pull out my 600ft. lb. Snap-on torque wrench. :D

    NICE, wish i had one of those.

    I used a 2x4 .250wall piece of steel that was in the garage and just slid it over a huge 7/8 allen wrench I got at the hardware store, and got it as tight as I could. Dont really have a torque spec on my exact foot pounds, but I figured 600ft/lbs was going to be hard to get since I only weigh 165lbs, so I got it as tight as i can.

    Instead of buying a 7/8" allan socket just stop buy a machine shop and ask for a piece of 7/8" hex shaped stock fall off. I'd get a length at least 5" long. The longer it is the more it will twist instead of shear off if it does decide to break.

    coime on what does it have to do with winning, if thats how he does it? I've got hydraulic torque wrenches at work.


    It makes me laugh everytime I hear someone say oh my gawd 600ftlbs on the king pin........ 700 or whatever it is on the D80 pinion nut :haha:


    We still have to torque some fluid end studs on some mud pumps to 2600-3200 by hand with the 4to1 :rolleyes:

    I'd imagine that twist is goin to reduce the torque getting to the kingpin...kinda like usin an extension.

    Well the twist takes place over time. Not all at once.

    the twist happens as you tighten the kingpin. the stock you are using will twist even more because it is not heat treated. as you apply torque the stock twists, you may not be able to see it, but it happens. it may spring back, but it still twists. that action reduces the amount of torque applied to whatever it is you are tightening.

    not saying it will not work, just saying u cannot achieve an accurate torque reading w/ a long extension.
