Why You Need This: A chain breaker tool is a must for your tool box if you are going to be wrenching on vintage motorcycles like the Honda CT90 / CB100 / CB125 / CB175 / CB200 / CB350 / CB360 / CB450 / CB500 / CB550 / CB750. We were getting tired of the issues found in the average chain breaker tool, so we decided to make our own and fix the pesky problems that have plagued lesser designs.
Our two areas of improvement are:
1) Tighter Thread Tolerances: The chain breaker tool relies on thread engagement between all the parts to press chain pins out or plates on. Many chain tools have very sloppy thread engagement which makes the tool more difficult to use. The additional play causes the center pin to bend or break off due to misalignment. Stripping the threads of the tool under force is also a frequent failure point on sloppy threaded tools. Our Common Motor motorcycle chain breaker tool has positive thread engagement, providing smooth operation, while removing all the excessive play between the critical tool components. This means less misalignment for easier use and less chance of ruining the tool due to threads stripping.
2) Locking Anvils: We have too often found the base anvil falling out of chain breaker too body when holding the chain breaker tool at various angles. This is especially frustrating when tying to assemble a cam chain master link. The Common Motor chain breaker tool feature anvils that friction fit in the lower half of the chain tool body, keeping them in place regardless of the position you are holding the tool.
Chain removal is a snap as this chain tool features multiple size drive pins for all common chains found on motorcycles (drive, cam, balance shaft, electric starter). The chain tool also has press plates for installing rivet style master links and staking end pins. The motorcycle chain breaker tool / chain press tool is able to remove links from 428, 520, and 530 drive chains that come standard on many vintage Honda motorcycles. The tool is also commonly used to disassemble cam chain or to install a press style master link on a cam chain. This chain breaker / chain press tool kit is built tough and we use it here in our shop daily. Replacement pins are available as special order items, contact us directly to order one.
Installation Tip: Lubricate the threads of the tool with a few drops of oil each time it is used. Refer to out setup video below to learn how to set up the chain breaker / chain press tool for each type of job. Always clamp the chain link you are pressing the pin out securely in the tool by using a 14mm wrench to tighten the main clamp screw against the link. A 14mm wrench can also be used to turn the press screw in and out versus using the included bar. When assembling our Common Motor press style cam chain master links, the inner press pin is not used, but rather the just the guide for the pin. The guide presses the plate over and onto the inner link. Proper alignment is very important when pressing chain pins to make sure they move as easily as possible. When pressing out pins you will feel resistance on the tool but smooth action. If the chain tool binds up, back off the center pin, snug the tool on the chain and try again.
