    Default Video on Cylinder Repair

    Here's an interesting (to me anyway) video on repairing a hydraulic cylinder.

    CSI Yard Man Part 1 - YouTube

    If you enjoy watching this guy, be sure to watch his "Broken Beaver" series of videos. It has nothing to do with hydraulics, but it is an impressive feat of repairing an abused piece of machinery.

    I like Keith's videos......he's got some interesting projects

    the scores he had in the cyl barrel were from the steel piston head (cast iron or alum piston heads cannot be welded) dragging on the steel cyl barrel (not from bad hyd oil)..........either a bronze welded overlay or a machined wear band would have been a better alternative

    the ball hone was definetly a no-no......too rough, it will wear out the hyd seals prematurely.....those ball hones are designed for honing combustion chambers with cast iron piston rings that will wear in to seat.......hydraulic seals don't wear in, they just wear out....
