Default Neat little trick I learned about meritor slacks...

Instead of taking out the adjusting pawl, use a flat screwdriver and "pull" on that round disk. This disengages the pawl. Adjust the brake, release the disk, and "wiggle" the 5/16 wrench to ensure the pawl is set properly. Done!

You just have to pay close attention to make sure it does not pop back in on you or you can do some serious damage to your adjusters.

a Flat screw driver or a teeny tiny little crowbar to fit underneath the Button :P

They actually make a little insert for that.
It's shaped like the claw on a claw hammer with a flat lip at the top.
They hand them out to mechanics.
A HD mechanic friend of mine gave me a couple but the screwdriver works just as good.

Taking out the pawl was for the early ones, they did not have the lift disc. The disc came out later (not much later because taking out the pawl was a PITA)

It is an auto adjusting slack and should not require regular adjustment.

Anybody still have manual slacks?

Has anybody replaced their auto slacks with manuals?

yeah, if you're using an impact wrench ;0)

use an open end wrench... it should not require much force to turn.

Have not replaced auto slacks with manuals but have replaced a whole bunch of manuals with autos, used Meritor, Haldex and Bendix autos.

I bet a DOT inspector would catch it if you did, all new trucks since some time in the mid 90s have had to have them.

Any thing built arter Oct. of 96 is supposed to have auto's on it. I have a 96 trailer with manual's on it and they've given me a little lip a couple of times at the scale. I've never gotten a ticket though.
