DAYUAN 13 pcs Motorcycle Chain Breaker Set, Chain Removal Tool Chain Cutter and Riveter Kit for Cam and 25 to 630 Chains

Great for the price

worked perfectly for removal, pressing, and riveting chain links together.

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.

Life saver! I always buy these and forget where I put them before I need it again. Hahaha!

Hard to use funky low quality several parts already broken But it did get the job done. Definitely get what you pay for. Update there customer service team reached out and resolved my issues.

Pins Broke on the first use, everything but the pins seem like good construction. i ended up having to use a nail instead of the supplied pins

Good buy. isnt the best but still really good for the price used about 6x

I was surprised to see that one of the most affordable options worked so well. I’ve used this on three chains so far and it’s been working great for me

Kettennieter/Kettenbrecher für den Preis Top! Funktioniert, wie er soll. Aber wie auch andere Kunden beschreiben, erst mit dem dicken Bolzen bis zum Kettenanschlag vordrücken, und dann mit dem entsprechenden dünneren Bolzen die Niet rausdrücken. Dann verbiegt sich auch nichts.

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.

特に曲がるようなこともなく、チェーンカット、カシメともに問題なく使用できました。 値段が値段なので、複数回使えたら十分。

The tool I got worked as it should. I cleaned the threads and then Lubed them with grease and when it was turning hard pushing the pins out I would just back it out a bit and then keep pushing the pins out. No problems at all breaking the chains. A great tool IMO for the price.
