    Lefty MAX 140 TPC hydrolic lock after oil change

    Rebuilt my Lefty MAX 140 TPC. Added oil after replacing the o-ring with a quad seal. I cycled the dampener several times, the same with the rebound assembly as it was inserted, to get all of the air out. I filled the dampener with oil so it would ooze out of the bleed hole when the rebound assembly was screwed in. Once togther though I could not cycle the dampener. So, I then removed the bleed screw and pushed in the dampener rod and then installed the bleed screw; I was then able to cycle the shock. But, will this cause air to be sucked in as the fork is cycled? Am I missing something here?

    [/LEFT]I'll go out on a big limb and guess that you didn't replace the foam compression compensation element on the compression assembly.

    It's the big black spongy thing on the lower end component.

    Yup, the sponge is there. I knew that it was the volume compensating part and important. I tested the fork and it seems to work doing as I mentioned in my post. Hmmmm, is the dampener rod supposed to be out or in when filled and the compression assy threaded in?

    It has nothing to do with the manner in which you did anything. The foam is saturated. It needs to be replaced. When it can't compress anymore, due to saturation, it locks out the compression circuit.

    I would take that bet also!
    That was exactly what happened with my fork. It was a previous post from MendonCycleSmith on this issue that really saved me from wondering what the heck was wrong. Mine had become saturated and was also breaking down and getting in the oil. My fork is pure magic now!
