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

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.

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.

I used this to break a # 41 chain, was easy to use and had no problems with it.

I personally use it for a RK 420MXZ 420x110 Kawasaki Z125 chain and it breaks it like butter. Super nice and very small but not too small where it’s hard to hold or grip!

Did the job, reason for 4 star is because the tool doesnt press center of the pin but close to the edge. I tried to reposition the chain but made no difference. It did however push the pins out easily so for the price I cant complain but it sure doesnt look right when you are clamping seeing it barely on the pin.

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.

The first time I used this thing it bent the chain links. Then when you do get it to work it won’t even push the pin all the way through. After pulling on the pin for ten minutes it had ruined my chain. NEVER EVER EVER EVVVEER BUY THIS THING. COMPLETE TOTAL WASTE OF Time, Money and a GOOD Karting Chain.

100% junk it works amazingly the 1st time and if you only need it 1 time buy it... but after that its next to useless the needle is soooooo weak it looses around 2mm its 1st use off a 8mm needle making it to short to push the pin out of the chain. 2nd time i used it , it screwed up my 35 chain cause i didnt realize this now than i looked at breaker and seen what did it. Before using it i did see the needle looked dented at the tip now the tip is gone after 2 uses!! And half of a $40 go kart racing chain is screwed up not sure if i can fix it. Very unhappy

So far so good. You have to push pin out from both sides. It’s not going to push pin out like a regular bicycle chain. If you do this the push pin should last just fine.

i only had to use it twice so far... and its been a non issue and worked every time.
