D60 KingPin Removal - brain dead question.

[combatmatt]

I know i know, theres TONS of ways to get these F*****g things off and searching yields 100's of posts and techniques,

-BUT-

Has anyone tried a 3/4" drive, 1000 ft/lb impact gun to break the kingpins loose on a D60? I realize its really simple etc etc but im wondering why no-one ever mentions going that route.

... im wondering why no-one ever mentions going that route.

maybe because the average do it yourself'er doesn't have a 3/4" gun? :idea:

Did you try it ??? did it work ???

I got a 90 degree bent 7/8" allen key and hit it twice with a 16 pound sledge. Both king pins came out easy.

I bought a 7/8" allen wrench, cut a short section off and used a 7/8" impact socket on the allen wrench then put a 4' cheater bar and gave a small tug and they came out effortlessly.

I'm with nvrenuf - just guessing that most hobby guys (i.e.: most guys on this board) don't have that kind of hardware. No reason it shouldn't work.

Ditto on 7/8 Allen with a cheater bar - worked like a charm. 3/4 gun should work provided the impact does not fracture the kingpin top.

The bigger question is though.....who other than myself owns a 600ft lb torque wrench to properly tighten the king pins to the spec of 600ft lbs.?

Not me but my spring shop does, they do 18 wheelers tandem dumps etc, got them to torque mine for me just had to bring it there.

The 2 monster trucks eradicator and backdraft are 5 miles away and the drivers are good friends of mine. I used theirs and it worked perfect , also they had a 7/8 allen from mac and a 3/4 gun....worked like a charm.

Physics--6 foot cheater bar and 100 pounds of pressure on the end, push until it stops turning

I figger at 600 foot pounds plus or minus 5 or 10 shouldn't be a huge problem

I've had one for many years, doesn't everyone have one?

For my recent kingpin rebuild I lucked out and found a friend whom had a Matco 600 Ft. lb torque wrench. the handle was like 4 foot long put together. I kept rearing down waiting for the click until my truck started coming off the jack stands. I looked down and realized I had inserted the "Clicker" portion of the wrench in backwards. Luckily I was able to back it off and torque to proper spec. I felt like Dummy afterwords.


IMHO to get them off 5 minutes with a cutting wheel on a grinding disc to relieve the tension off the kingpin is the easiest. It twisted out with just hand force.

Sweet. Only reason i ask is that my buddy just got a job as a heavy equipment mechanic (mobile type) , now when he stops by the house theres a traveling shop with him. So yes while the average do it myselfer dosent have cool tools, i can borrow them now if i have extra beer laying around.

There are also things called torque multipliers, they work well to make stuff come off or to torque stuff to retarded numbers with just a snappy 250 max wrench.
