A simple and effective tool that makes compressing the valve spring for keeper removal a snap. Simply hook the "C" hook over the rocker shaft, locate the "L" hook over the spring cover plate, and press the handle downwards to compress the spring.
The keeper can then be removed and the valve spring separated from the valve.
To re-assemble, just perform the steps in reverse order to re-install the keeper. It's that simple.
Works like a champ on big bore Continentals valve springs. The adjustable reach is easy to set-up for a particular application.
Worked good for a while but broke a tooth off while using. Expensive tool to fail in the middle of a job for no reason!
