Now available from Aircraft Spruce is the C-01 Dual Action Valve Spring Compression Tool, which was developed to ease the removal and installation of Continental engine cylinder rocker arms, rocker arm shaft and valves, valve springs and stem clips.
While valve spring compression tools are available and have been for over 60 years, most compress only one valve spring at a time, leaving the opposite still in tension. This often retains the rocker shaft, making its removal difficult without force, company officials explain.
The C-01 Valve Tool is attached to the top of the cylinder, and in one action, compresses both valve springs to remove the rocker shaft and rocker arms.
When installing the rocker shaft, the C-01Valve Tool eases alignment of both rocker arms as they are passed through the rocker shaft bosses.
The C-01 is manufactured specifically for use on Continental C65/C75/C85/C90/0200/C0300 engines.
