    Go to move a truck this morning and it won't build air. The old AD-2 Bendix dryer is stuck open and bleeding straight from the compressor to atmosphere. I remove the discharge valve and it's a mess so after taking it apart prior to going in the tumble blaster:


    And 10 minutes later with thoroughly worn out media at 80psi:


    Reassemble with silicone grease on the sealing rings and it works like new.

    Got the truck moved out of the way and I'll probably take this back apart to get things painted up so corrosion doesn't take hold.
