Mac 1/4" ratchet (mrr6fpa) assembly question.

[waterboy12]

I was using this ratchet and it suddenly started free wheeling. Took it apart and now I can't the mechanism back together. I've never seen anything like it. There's is some type of spring thing that I think is supposed to attach to a tang on the pawl selector. This thing is driving me crazy. Help me out.

Place the tang on the inside of the V portion of the spring and then slide forward (while pushing down) so that the tang ends up outside the edge, squeezed between the edge and the spring.

Got the tang on the inside of the spring sandwiched in between the spring and the edge and it will grab for a sec and the free wheel

You might have to adjust the screw 'just so'. The design is somewhat sensitive when it comes to that.

I'll keep messing with it and see what happens

Seeing how that mac ratchet is essentially a facom design, cant see why it wont work.

Step 10 is the important part now. Tighten the screw all the way and then back off 1/4 of a turn and see how that goes.

Thanks a lot guys.

Might need a dab of threadlock on the screw too.

I got it. Had to play with the screw a little, but I got it. Thanks for the help guys

I recently took apart my MAC torque wrench that has that mechanism. Took awhile to get it back together.

I believe the proper screw tigtening is this process-

Tighten screw all the way down
Back off 1/4 turn

That's from memory. I could be misremembering.
