Chain breakers

[Chino886]

What kind of chain breakers does everyone use? I was thinking of either the Motion Pro or the Tusk. The Tusk is cheaper of course!

Compressor + pneumatic grinder.. lol. I just grind off the 2 rivets flush to the outer plate and it comes right apart.

A handfile works too, in a pinch.. but takes a lot longer. ;)

I've boughten a couple different chain breakers, and haven't found one that worked worth a crud.

yupp, or an electric right angle grinder works well to. all i ever use, best chainbreaker out there.

A chain breaker and an air ratchet is much faster and cleaner than any grinder.

The motion pro will work fine for 520 and smaller chain. I have a bench mounted breaker for the bigger ones.

you'll do fine with the motion pro.

most of the time,unless its late at night or I'm at the track or soemthing, I use a grinder. I keep a chain breaker in the tool box in my truck, at home I rarely use it.

Correct me if i'm wrong but don't you have to grind the outer rivets flush whether you use a chain breaker or not?

Case in point: A couple years ago I purchased the full size Motion Pro chain breaker. Not knowing any better, I went at it with my stock chain. After a few cranks of my 3/8 ratchet, I noticed that I completely cracked the threads in half on the chain breaker itself.

This is the one I have, the large outer threads split in half when I was tightening the internal pin:

I took it back to the dealer I bought it from and they generously offered me a replacement, but told me I need to grind the rivets down first.

Anyone know if this is true or did I get a defective tool?

i've never ground down the ends. ofcourse, the times that i've needed to use my breaker i'm 5 miles from no where setting in the middle of a creek bed lmao.


btw: is this a m/p breaker?

Yeah that's the Motion Pro ^^^

[deathman53]

mine, is the same style and pushes the pins out.

I have a tusk and it works just fine

[NacsMXer]

I guess I just got a defective tool then, at least I got a replacement for free! :D

How long has Motion Pro been in business? I have a chain breaker just like the one in the pics posted that I purchased 20+ years ago. It has pccc stamped on it in three locations. I'm assuming it's the same, just wondering what the history is.
