Abstract
An easily accessible phase adjustment mechanism for a vibratory plate compactor includes an improved seal arrangement to protect against leakage of internal lubricating oil into the hydraulic cylinder providing fluid pressure to the adjustment mechanism. An easily demountable cylinder housing provides ready access to the piston and seal assembly which can then be threadably detached and replaced in its entirety.
