RedVise, me thinks (big SWAG here) that your ratchet has a water wheel type of gear system. That little flat bump on the one side of the head is right where an external set screw would normally be with a spring and pin behind it. Maybe you could snake a thin piece of spring steel down through the hole in the top and prevent the pin from popping into a gear groove and then it might slide out?

Sort of like this:

Yep, looks very similar, but there is not  a externally accessed  set screw, or opening at all.
So (my SWAG) is that there is a spring and pin, but they are loaded from the center, and the ratchet mechanism is then  inserted in the center  and a set screw is used from the top (somehow). Ta Da !!

No patent number to use either...

I have got the ratchet mechanism freed up, who hoo 10teeth !!
Have tried depressing the pin, no success.
Will keep shooting the lube to it and trying to push done on the pin.

"Technically" not gearless.  I believe I counted ~250 or so clicks in mine.  I haven't had the cajones to try and use it in a hi-torque situation yet.........wonder how strong it is?

Mine is not very strong at all, but it's worn out though.

Hi all,
I have two older ratchets that I would like to fix. Do any of you have for sale or know where I could buy repair kits for a New Britain 54 3/8drive flexi head ratchet and another repair kit for a MAC XR8-P ratchet. If anyone has these for sale could you please quote the price including shipping to Malta? I have already contacted MAC in Europe and they do not a repair kit for this ratchet anymore. Thanks in advance.

I'm betting most are worn out.  I have 3/8, 1/2 and 3/4 drive versions and I'd really like to try them but I'm a bit leery of either breaking the ratchet or my hand.

You know, kwos, the more I look at your ratchet internals the more I see coaster brake parts on a bicycle rear hub. Forward = spins free. Back pedal = a set of tangs push the brake wedges out and rub on the inside of the hub.
Since yours are worn (and thus slipping under load), I'm wondering if you couldn't arc weld some small blobs onto the outer edge of those parts and then grind them smooth - but not totally down to the original steel. That extra couple thousandths of a inch my be enough to fully lock it when used. Maybe? IDK

How about cutting some slight groves across those wedges with a file so they bite better.
A person who could really read human minds would be privileged to gaze on some correct imitations of chaos.

Anyone over here (Bonneyman  ==  Twertsy) know anything about this wards ratchet?  Who made it for Wards and when?

Apologies for the massive delay!  I believe it's Truth if I recall.

Yeah, sorry about the delay. Been real busy with too many projects and honey-do items.
