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

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.

Please grind chain a little first,, this is a great tool and well worth money,yet it's clearly from negative reviews that it's their first time using these tools.. you need to grind first not much enough to push through with this tool, or it same as forcing a square peg through round hole it never going to work... Grind first and this tool will last you many many years... Well built and strong and not cheap metal of which inexperienced say it is when it is not..this is as good as most expensive chain breaker at fraction of cost.. Very good buy from Amazon for a change and not ripped off as I have been previously and no help from am.. Buy it then light grind and use it's a great tool

If I could do 0 stars I would. All the parts just bend under any pressure. Threads just sheer off, could be one of the worst bits of kit I’ve ever had the misfortune of using … and here’s the funny part , I got 2 of them ! Both of them bent on the first rivet meaning I had to get a new link for my chain. Do yourself a favour, don’t be cheap and get a more expensive better quality product.

Honestly, it works fine, used it on a 520 chain, ground the head off, and it pushed it through just fine, what I image people have done is set the removal pins way way too far out of the screw cover and they’ve started to bend, they haven’t noticed and the pins break, I used it twice to break links, it worked fine, however, I’m not 100% on the riveting, it did start to open up the tool and I’m not 100% sure it’s actually riveted it much at all, I’ll risk it but honestly, that’s the only gripe I have with it, is it cheap? Yes, does it work? Yeh mostly, especially for actually splitting the links, works just fine for that

A quality chain tool, at a fraction of the price of its competitors. After using others, this tool is the best. Works exactly as required and with ease. Flaring the rivet on the pins is the most straight forward of all. Well worth the money

Robust kit invaluable for bikes

I wasn't too sure about this after reading other reviews. However it has worked flawlessly on breaking the old and fitting a new 520 x-link motorcycle chain. The 3.8mm pin was spot on for splitting the chain (after grind off the head of the pin). Then using the press plates to fit the new master link, and slowly tighten until it is the right width was so easy. The kit also comes with clear instructions in English. I just wish I had bought one years ago. [Note I haven't used the rivetter yet.]

This product is cheap and low quality. I should have listened to the other reviewers when they described this tool as monkey metal. That is completely accurate. I bought this tool to change my motorbike chain and I followed the instructions to the letter. I grinded down the rivets on my old chain before using the chain removal tool however when pushing out the old rivets the removal tool bent, deformed and I was lucky to get them out before it completely broke. When installing my new chain, the riveting bit completely snapped and I had to try and use whatever I could to properly install the chain. Don't risk being unable to break and install your new chain. Spend the little extra cash on a decent quality tool you can trust.

Geen geld voor een heel goede tool, gebruikt op moto en brommers!

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.

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

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。
