thomastractorsvc Posted July 16, 2017 Share Posted July 16, 2017 They are auto adjusters or should be. Not sure of the style of your cam but should be a snap ring and couple of spacers. Undo the clevis pin and should come off if it's been taken care of. Might have to use a puller or a hammer to knock it off. auto adjusters don't need the same maintenance adjustments manuals do usally adjust and keep greased until it's time for brakes. The more you mess with them the more issues you will have. 1 Quote Robert"I reject your reality and substitute my own." Link to comment Share on other sites More sharing options...
