Fix Broken Skateboard & Longboard Truck Kingpin

bjbj What I ve got here is a skateboard truck
that is completely taken apart and I ve got some new parts right here that I m going to
replace some old ones with. Now, what happened to this truck, the kingpin broke and I ve
got to replace it with a new one. Now, the kingpin is the big bolt that goes through
the baseplate and it holds the whole thing together as one unit. Now, what I m also going
to do is replace the bushings. The bushings can sometimes be the cause of breaking the
kingpin because they do get old, the oil evaporates out of them and they can crack. Now, the color
is not just for looks it also determines the bushing s durometer. Now you want to make
sure you match the durometer with your other truck that s still on your board, because
what s going to happen if you don t is you could end up with a truck that s too hard
or too soft and your board is going to be lopsided. So, what I m going to do now is
show you how I m going to take it out. This kingpin broke flush. If yours didn t, file
around the edges of the kingpin, because any little shard is going to make it difficult
to hammer out. I m going to use my new kingpin to hammer out the old one, and I m going to
use my shoe to hold the baseplate in place. What I ve got to do is line up the new kingpin
right on top of the old one and just start hammering really hard, but I m only going
to get the kingpin out about halfway because the bottom of it is going to hit the ground.
If you re going to do this, make sure you re right on top of that kingpin when you re
hammering and that you re also at the right angle or you re going to ruin the threads
of the new kingpin. Now you can see how much of the kingpin I ve got hammered out and it
s about a third of the way and you can see what the other side looks like. From the side,
you can see that the kingpin is already sticking out a little bit at the bottom of the baseplate.
Now, I m going to hammer in the rest of the kingpin out on the grass. You can start on
the grass if you want to, but there s just not enough resistance because the grass is
too soft, but since I ve already got it started on the ground, it s going to be a lot easier
to hammer out on the grass and you can see that when I was hammering, it was a lot easier
and it just popped out. Now that I got that broken kingpin out of my baseplate I can now
stick in a new kingpin. Now, newer types of trucks require newer types of kingpins and
the newer ones have the rounded ends and they have the splines which are the raised edges
and grooves on the end of it. Now, you also find the splines inside the baseplate. What
you ve got to do is line up these splines by slipping in the kingpin and just spinning
the kingpin until it lines up with those grooves and there we go just give it a little push
with your thumb to help it just kind of get into place there. Now, if you don t line up
the splines, you re going to be hammering this kingpin in for days, so really make sure
that you get them lined up right. Now, for older types of trucks, they have the hexagon
shaped-end kingpin. They re a lot easier to get in, and all you would have to do for the
older types of trucks is just put the baseplate between two two-by-fours, maybe take a new
kingpin or take your old one and just start to hammer it in. Now, that works great for
the older ones, but unfortunately for these newer ones, they require you to hammer as
hard as you can and it takes a lot of work. What can happen with all that hammering and
all that pressure is the baseplate can crack or the hardware goes in and it can also crack
in the center. So what you want to do for these newer ones if you want to put all the
pressure for when this thing is going in around the kingpin and just on the really heavy part
of the baseplate. So, the next best thing is to take a big socket, now a long one, and
just kind of make sure before you do this that it s going to go down all the way. So,
I ve got a long enough one here, I ll slip it in there, and since I ve got a whole set,
I ve got a smaller socket here that s perfect size and I can just start hammering it down.
As you can see, I duct-taped the socket that has the kingpin inside. If you need to, you
can duct-tape another socket on the other side which is the one you re going to be hammering
on just to hold everything in place as you re hammering. I put a little piece of duct-tape
on the ground to keep the whole thing from slipping. Once I get a good hold of everything
I can start hammering away and it looks like it s going down just fine!
Yup, looking pretty good. Just double-check to make sure that it s in all the way. Yup,
that one looks perfect! As you can see, hammering in that new kingpin wasn t that hard. Now
I have a quick question for you: how many bushings are in one truck? I wonder how many
of you said two. There are actually three. Most people always forget the small pivot-cup
bushing that s inside the base-plate. Now, that can be the cause of the kingpin actually
breaking in the first place. They wear down; they break down, so it s a good idea just
to replace everything and so now let s go ahead and put it back together. So we ll start
with the big washer and we ll stick the big bushing in, take out hanger, stick it on,
now we ll stick on the small bushing with the small side up now the small washers, before
I put them on, I want to point out that sometimes these can get dented in pretty good if you
like your trucks really tight, and sometimes they could actually completely flip over (they
ve got a little bit of a lip there, sometimes they ll totally flip.) So, if you ve got one
that s dented in pretty good, it s a good idea just to go ahead and replace it, it s
not that much. So, I ll just go and now stick on my kingpin nut, tighten that on there a
little bit. Now, all I ve got to do is tighten it down all the way and match it up with my
other truck and I can go skate! [email protected] [Content_Types].xml _rels/.rels theme/theme/themeManager.xml sQ}#

  1. I personally have not tried to put a theeve kingpin in an independent baseplate, but I don't see why it wouldn't fit. Remove the kingpin from the independent truck. You may have small pieces of metal blocking the kingpin from going in. The smallest piece of metal can make it very difficult and frustrating to put a kingpin in. Inspect the baseplate where the kingpin goes in and see if there anything in the way. Then have someone with some bigger muscles (no offense) hammer it in for you.

  2. The splines in my kingpin hole are gone for some reason. Do you know what caused it? And the kingpin splines are not straight.

  3. I'm not sure how you cut the kingpin, but it's probably not budging because of a tiny piece of the metal. You'll need to hammer it back in, file around the end of the kingpin and any damaged area, and then try to hammer it back out. Buy harder bushings so you don't have issues with the washer flipping.

  4. Ok i was skateing and snapped my king pin and it didnt break flush it broke futher down in the hole and no matter how hard i hammer it wont come out any tips?

  5. Is it a hallow kingpin? Kingpins can be very difficult to remove if you don't have the arm strength the do it. Sometimes someone with more muscle power can hammer it out.

  6. I have thunder hollow lights and broke the kingpin the other day skating i prefer my trucks really tight. The kingpin broke half way down the base plate, not flush. Ive been trying to use the other half of the kinpin to hit it out with a hammer and hasnt moved at all.

  7. So my Indy kingpin broke but not flush like what you said in the video. They broke inside the baseplate kinda how it was at 1:21. So I though It would be easier to hammer out. But I hammered as hard as I could and even got my Dad to help and it didn't budge. I did everything in this video and the kingpin will not move. Any suggestions?  

  8. Thanks alot again, had this problem before and could not remember how to get it out. Using another kingpin to get it out was just cake compared to what I was trying to do.

  9. I have Thunder hollows and I need to replace the kingpin because the top part is worn down from concrete. I have tried twisting and hammering the kingpin and it still won't come out. Is there anything else I can do to take it out?

  10. I would have recommended partly assembling the truck and tightening the nut to pull the king pin through, little mechanics trick for replacing camshafts and such.

  11. My trucks base plate holes widened up and i have no idea why.Can you tell me how this happened and how to prevent this from happening again

  12. Will my trucks break easier if I replace the normal kingpin with a hollow kingpin from the thunder trucks hollow kingpin replacement kit? ( have thunder lights)

  13. my kingpin got loose threads and theres no way to take off the nut,i dont have anything to cut the middle of the kingpin what should i do? please reply 

  14. I have a pair of thunder hollow lights and the kingpin is so damn hard to get out is hammering away the only solution because it's not moving 1 bit??

  15. ayyy dude can really skate tho? why haven't you posted a vid of you skating bro? you should really post one tho

  16. Dont use your new kingpin to bash out the old one!!!! Stress and fatigue causes them to break in the first place. By using your new kingpin as a punch, and hitting it with a hammer all you are doing is stressing it, and with each hammer blow possibly causing damage, incresaing its risk of early faliure. Use a punch, or an old bolt that you're not going to use again. Come on if you're going to make tutorials teach the right way, not the ghetto way.

  17. I broke my thunder trucks a week ago sadly I discovered it has that hollow kingping and those lines at the bottom. I can't release that part from the base even when I hammer it, suggestion will be great for me

  18. For some reasons, I cannot find the right length kingpin for my trucks. Normal ones are too long, and low ones are too small! What would you recommend? Adding washers?

  19. my trucks get always loose… it doesn't matter how tight they are.. the get lose… and the kingpin comes like 1 cm out from the kingpin nut… what should i do? thank you! 🙂

  20. Broke my Destrucos today and I was wondering how to replace them, since they advertise the "Life Time Guarantee" on the bottom of the base. Do I go to my local shop, or ship them to the factory?

  21. I broke my kingpin yesterday. I tried the whole hammer thing but it wont moved. The kingpin broke halfway up the shaft. Any ideas on fixing it?

  22. I got a pair of forged titanium indys from ebay but one of the kingpins is a bit crooked. I don't know if it's the kingpin itself or if that's due to wrong placement. I'm a bit afraid to take it out. I don't want to damage it further. What should I do? Will a slightly crooked kingpin affect the durability of the truck? Will it make such a difference in my skateboarding? My deck is still on the way so I can't test it yet.

  23. If the kingpin snapped and I hammered it out like in the video and then found out that the grooves that hold the kingpin to the baseplate are stripped do I have to buy new trucks now?

  24. I wanted get my trucks a bit loose , but the kingpin is complete loose and i dont get my trucks and kingpin back on my board

  25. instead of hammering th kingpin in cant you just put a spacer on the other side along with a nut and screw it in

  26. What a fucking numpty way to do it. Rest it over a vice, or a socket, and use a real punch, rather than fucking the bolt you were replacing it with. To get them back in, put a stack of washers or a socket over it, and tigthen the nut down firmly to press it into place. Undo the nut and install your hanger in the usual fashion.

  27. kingpin nut is stipped on from so many 50-50's that I cant change bushings, help please because i already bought new bushings .Lol

  28. How do I fix a truck washer the top one. It's stuck I can't tighten the truck or take off the nut. That top thing on top of the bushing is destroyed and squished help please

  29. on my truck, the nut that holds everything in place(the nut you use to loosen/tighten your trucks) is stripped really bad, do you have any tips?

  30. If you freeze your new kingpin overnight sometimes you can press it in without hammering and when it warms to room temp it will expand and lock in place. Tolerances aren't very exact in the skateboard world so some might require some hammering but it will still be easier the colder you can get the pin. I'm aware cold makes metal brittle but the temperatures in your freezer won't be extreme enough to damage your kingpin, especially since you won't have to hammer the shit out of it to get it in your baseplate.

  31. "Take the new kingpin to hammer out the old kingpin. And then order another new kingpin and use that as new kingpin for your trucks."
