main cilinder in mast (# D-30389) does not lower, unless i add about 130 lbs of weight

I removed the chains and the carriage lowers with no problem, the cilinder does not lower i disconnect the hidraulic hose from the control valve and the cilinder itself, and it will not lower i have to add weight in order for the cilinder to lower, Is there a check valve inside the cilinder? or is the packing keeping it from lowering?any suggestion before i repack the cilinder? it lifts ok and does not leak.....

i found that the pin holding the check valve inside broke damaging the gland and i had to replace the cilinder shell and the gland at the bottom it works great now

Fact of the week
Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
