AZSSMUK Roller Chain Breaker Detacher Tool for Size #25#35#41#40#50#60 415H,428H, 520,530 Motorcycle Bicycle Go Kart Chains Replacement

Seems kinda wasteful though, I had to buy this really nice chain breaker to size the chain for my motorized bike, and I’ll likely never use it again. This is the kind of thing that auto parts stores should have in their loaner tools selection. Or the local maker space should have, though dues at a maker space are usually insanely overpriced. Anywho, good chain breaker.

Its not big enough to actually fully detach the chain on a #40 dollar chain. It can loosen the pins so you can get it apart, but if youre trying to completely remove the pin between the links, its not going to work, the pin isnt long enough to push it all the way out.

Have a 415h chain. Destroyed chain. Bends it. Doesnt push out the pin. Not new at this. Tried again. And same thing. Pushes pin out a little then proceeds to bend the chain. Been breaking chains for 30 years. Never seen anything like it.

Ok so it worked. Took about 4 minutes to break the chain slipped off a couple times but I will chalk it up as user error. Solid construction. Grab and hold abilities are a little bit weak... but again the product worked for a dirt bike chain.

I have a manco dingo go kart and I needed to replace the chain. This worked great and Im pretty sure i can use it many more times

If you are looking to remove chain and the chain is welded, this is a good part on non-welded components like chains when trying to break them...

Use for go cart chain replacement. Worked great. Easy to use. Pretty good quality

Just what the doc ordered for them ear piercing^__~ NO, please dont do that^__^ This is great! 47 and I never had one this heavy duty before! Should last me another 47 if the ticker/? does^__^ ENJOY!

Exactly what I needed. Shipping was fast, item worked perfectly, and is good quality. Thanks!

In Q &A section, someone asked if it would work on 530, 525, 520 chains and seller replied it would. I decided to call bluff and purchase it. Technically, it does but requires some grinding. It Will Not Work On Factory Pressed Rivets on 530, 525, and 520 Chain Without Grinding/Shaving Rivet A Bit First. It could work on the non-factory DYI rivets with the dimple on it without grinding. Chain I used it on was a 525. The Push Pin in device flattened (not harden steel) and felt like tool would break. Wished Id took a pic of it before tossing and installing the spare. Overall, its a solid design but intended for bicycle type chains or smaller.
