DAYUAN Motorcycle Chain Breaker Set, Chain Cutter and Riveter Kit, Red Case

Works great, does the job on large motorcycle chains. just make sure u have a grinder also.

This tool was terrible. I read the instructions twice and watched several YouTube videos on how to use it to make sure everything went smoothly and I was confident. Which I was. But when time came to break and rivet my chain, it was extremely difficult and it constantly felt like something was going to break. The tool had me continuously thinking, "Am I doing this right?" I managed to break the old chain with this, but it wasn't easy and it deformed the 3.8mm pin in the progress of doing so - eliminating the potential for future use of this tool. Then, when it came time to rivet the new master link chain... same situation. Extremely difficult, constantly fussing with the tool, returned to watch YouTube videos two times to verify proper use of the tool. As I cranked down to rivet the master link, it felt as though it was pushing the links plates tighter together, which is not supposed to happen at all at this step... and then the tool snapped in half. Sparks flew and the metal sheered. "Wow..." Luckily i didn't get hurt. This tool is clearly built for one time use and not meant for installation on a quality made chain. I will have to find someone with a better chain riveting tool to finish the job for me. Money and time poorly spent ordering, waiting for and using this tool.

Great for the money! Used it to rivet a 530 chain on my Harley and had no issues at all

This is a solid tool. Seems like it will last over time. Easy to use & comes with instructions. FYI - This is a real review, not a bot or AI.

Used to drive pins from a #60 chain. The driving screw stripped the threads on the first use. ***Updating my original review from one star to four stars, for the sellers customer service. This chain breaker remains flawed; this should be made from tool steel and is not- rather soft carbon steel. For lightweight chains (EG bicycle) this breaker would probably work fine. For larger chains like a #60 or #80 I would look at something else. The seller reached out (After the return window was exhausted) and offered a full refund.

Review: DAYUANTOOLS Chain Breaker Kit (Amazon) I picked up this chain breaker kit for basic motorcycle/dirt bike work, mainly for a 420 chain. Overall, it does work, but there are some pretty big limitations you should know about before buying. Pros: • Comes with multiple pin sizes and attachments, so it’s a complete kit out of the box • Compact case keeps everything organized • Affordable compared to higher-end chain tools • Easy to use for light-duty jobs or smaller chains Cons: • The biggest issue: the pins are not very strong • While using it on a 420 chain, some of the included pins started to bend under pressure • Doesn’t feel durable enough for repeated use or tougher chains • You have to be really careful lining everything up perfectly or you risk damaging the tool Performance: It will break a chain if you take your time and don’t force it, but it’s not something I’d trust for frequent use or stubborn/rusted links. For a 420 chain specifically, it’s right on the edge of what this tool can handle. Final Verdict: Good for occasional use or emergencies, but not ideal if you’re regularly working on chains. If you plan on doing more than a couple jobs, it’s probably worth spending more on a stronger, higher-quality chain breaker. Rating: 3/5 ⭐ Works, but durability is questionable—especially the pins.If you want, I can recommend a stronger chain breaker that won’t bend on 420 chains 👍

Look good

Don’t waste your money on this non of the parts in this set even work together and the cheap Chinesium metal that they use bends if you even try to break a chain bigger than a Honda grom. Horrible product, even after I angle grinded it to all hell it still could break the chain apart. DO NOT BUY THIS

Werkt super.

La herramienta es perfecta. Dura como ella sola. Los pasadores no los doblas ni queriendo. Probe a subirme al fino con todo el peso de mi cuerpo y ni se dobló. La primera vez que extraí la cadena si que me puse a rebajarlo, que tardé un buen rato con una dremel. Cuando saque el remache y lo investigué... vamos me hubiese apostado todos mis ahorros a que lo de rebajar es una chorrada porque el remache no llega ni a 1mm, es IMPOSIBLE que un acero por muy reforzado que esté aguante la presión de esta herramienta. Pues tras probar con otro eslabón de una DID 520 VX3.... Ha salido como mantequilla sin rebajar ni nada. Lo importante es la técnica! Mirad videos en YouTube que lo explican perfectamente. Primero es que la tuerca interna de la herramienta hay que usarla para centrarla bien sobre el pasador y aprisionar la caden fuerte (No pasa nada porque reventamos los X-Rings que van a cambiarse, pero debe quedar bien fija y centrada). La tuerca externa es la que se gira para sacar el remache y solo hay que usarla con el palito que viene con la herramienta... Así es imposible que doblemos nada a menos que seamos Thor, claro. Si no sale con eso, es que la herramienta no está centrada y punto. Además que hay que usar el tamaño del pasador oportuno. Lo único que no me ha acabado es el pasador de remachar la cadena... He partido un remache porque tiene una forma demasiado plana y cuesta verle el punto. Pero también ha sido porque me he motivado. La herramienta de verdad que es una pasada por el precio que vale. Lo que pasa es que hay que saber usarla.

Despite the mixed reviews, I found this to be substantial bit of kit. I have only used it on a 520 chain, which it handled easily, but with the different sized anvils and push pins I would be confident in tackling a heavier chain with it. The instructions only describe which parts to use for breaking and riveting but no great detail how to actually use them, and the press-plate is difficult to keep lined up over the link plate pins before they are pushed proud, so for that reason I only gave 4 stars for ease of use. The pins fit inside the larger threaded bar and seat onto a spring. They are then wound down with a smaller fine threaded insert. You need to position the breaker pin with only a millimetre or so protruding, and then wind the entire assembly down to contact the ground off link pin. You then wind down the smaller fine treaded bar to push the breaker pin through the link. Once the link pin is being pushed from the chain, the breaker pin follows it through and is kept straight by the chain. As long as you use the correct size breaker pin, don't have loads of it poking out before too start and grind off the link pin head, then you should have no trouble. The rivet tool is equally robust. I managed to split the hollow rivet wide open and break it by applying too much pressure. That was my fault and not the tool, but I mention this to demonstrate how surprisingly strong this is. The same kit is available from other sellers at varying higher prices, so if you need a chain breaker/riveter then you may as well get this one as its the lowest price you will find it for. All in all, this could only be improved with slightly more detailed instructions and perhaps a lock for the press plate to keep it lined up with the link plate pins as they push through. Two minor points, and certainly not enough to make me unhappy with this kit.

Ottimo prodotto. Resistente e molto maneggevole.

Macht einen soliden Eindruck. Habe ich für den Notfall im Reisegepäck.
