    I pulled my rams today to do some painting. The older ST-90 rams I could compress by hand, and squeeze the oil out. The newer ST-7.5 rams are frozen, and would only move when standing on end, and being struck with a sledge hammer. Anybody out there ever experience this? Is there a fix, or do I replace them? Thanks for any, and all input!:salute:

    If your cylinders don't leak then their's no need to replace them. It's normal that you can't compress them by hand. If you can compress them by hand, like you mentioned that you could on your old ST-90, then that's usually a sign that the packings are worn and need tightened or replaced.

    Should the ST-7.5 rams be so tight? When hit with a sledge they only compressed about a 1/2 inch. :redbounce

    It's not uncommon for them to be virtually unmovable by any other means other than hydraulic pressure, but be sure and check them to make sure they're not bent while you have them off. BTW, you do have the hoses disconnected from the cylinders right? Just checking..

    Yep, hoses off. I just thought it odd that it was that hard to compress them. Thanks for the info B&B.
