How do you replace your new chassis with the old one on your inline skates?

You should know first and foremost that you can't always swap out. Depending on how the holes from the original frame line up with the holes from the new frame, you might not be able to make the holes necessary. Think of it like this: If the holes are all off just a tiny bit, when you make new holes for the new frame, you'd be turning the old ones into ovals, which means your frame will not stay in place. For this reason alone, I advise not trying this yourself unless you know what you're doing. With that said, the simple answer is to take the skates to a local shop and ask them to do it. Shouldn't cost more than $40 for them to swap chassis and they can have it done in an hour or so.





If you want to do it yourself, here's a step-by-step for you. Removing the old chassis is the "easy" part. First things first, take a Sharpie and trace the base of the old frame. This will help later. You'll need a power drill with a 3/8" or so bit. Take the laces out completely. Remove the footbed. You should now see the rivets on the inside of the boot. The next part will be a lot easier to do if you have access to a bench vise or something to clamp the frame in. (Notice I didn't say to take the wheels out. If you're going to clamp, the wheels will keep you from clamping too hard and bending the frame.) Take the drill and put it on the top of the rivet and SLOWLY drill it out. You'll have to do this for all the rivets, probably 10 per skate. Mind you, don't drill all the way through, just enough to get the head off the rivet so it falls out the bottom. Once you do that to all the rivets, the chassis will come right off.





Putting the new one on is tricky. Using the tracings you did earlier as a guide to make sure you're putting the new chassis on straight, lay the new chassis on the boot. Make sure you don't have that overlap of holes I was talking about before. One or two per boot is okay. More than that I do not recommend swapping.





Here's where you reach another fork in the road. At this point, I'd take it to any skate shop and have them mount the frame. They will use rivets, which are lighter but just as strong. They will also make sure the frame is lined up right. It should be cheaper and quicker because, frankly, you've done 1/2 the work for them.





Again, if you're stubborn, here's the rest of the steps. You're going to need mounting bolts which you'll have to buy from a skate shop. Once you have the frame lined up, carefully mark the holes with your sharpie. Make sure you don't move the frame. You're doing this because you don't want to drill through the frame itself. It's too easy to damage the holes in the frame that way. Mark all the holes, remove the new frame. Take a drill bit that fits the holes in the frame (or existing holes in the boot) and drill straight down slowly. I say slowly because you don't want to go too fast or too far and drill into the tongue or liner of the boot, right?





The rest is cake. Put your bolts through the bottom of the boot. (Again, skate bolts with a flat head, not some bolts you got at Home Depot.), through the frame, put a nut on but don't fully tighten. Repeat for all holes. Once you have all the nuts hand tightened, use a wrench and tighten them all down evenly. You might even want to get some Loctite and put a drop on before tightening the nuts to make sure they don't come loose on you.





(Now, that's called bolt mounting. I should point out this will add some weight to your skate. The benefit is if you have a problem you can take the frame off yourself.)





Hopefully that made sense for ya!

How do you replace your new chassis with the old one on your inline skates?
It depends on the type of inline skates you have. Many inline skates are premium models or custom assembled from boots and frames that are intended to be removed, upgraded or replaced.





If you are not sure if your skates are a permanent package or made from individual parts, go to a rink pro shop or a sports shop that builds custom skates, and they will tell you what your frame options are.





Once you know that your skates can be re-built, order your boots first, try them on before mounting to make sure the fit is good, then have the sports shop professionally mount them to insure that the frame is properly balanced on the boot.





If you are asking this question on a public forum, do not do it yourself. A bad mount will affect your skating and balance in ways you don't want to know about..
