Screw type bead breaker

[JohnDeere8530]

I have one of these cheapo sparex Chinese jobbies

Is it ok to use an impact wrench on it or will it break it ?


Main top nut appears to be attached to the long internal thread by means of a roll pin only. Maybe a torque limiting device ?

We have had one years now it's been on the impactor a few times and been ok but it's not the strongest thing and has had a lot of weld repairs.last time I over did it on the impactor I snapped the clamp jaw in half so that's welded up with a bit extra bracing

There's a grub screw running in a slot to keep the jaw straight. If you go too far with the impact it will bugger up the screw and slot. Hand ratchet or air one is less likely to damage it.

Just broke the roll pin on ours with an impact...... tap it out, drive a new one in and carry on!

Neighbours one had been run too far, jammed and broke the pin. I got it apart, replaced the grub screw and welded the nut instead

If you bought a chuck to socket drive adapter, maybe a cordless drill would be better. You don't really need the harmfull shock of an impactor.
