|These simply bolt to the head and the knurled knob screws down to compress the valve spring allowing the shaft to be slid out with no spring pressure.|
Worked as advertised. No complaints thus far but only used it once.
These worked great on my A65.
Iâve got a couple of homemade tools that are minimal, so I decided to try it and see. The angle of pressure applied to the valve spring ensures that the spring remains level. Simple to use. I rarely need the tool but itâs worth every penny in simplify the process. Perfect.
This tool is great when reinstalling rocker arm shafts on aircraft engines. A must have item for my tool box.
Worked great on my Lycoming 0320 with some minor clearance filing.
This tool is invaluable when reinstalling rocker arm shafts on continental engines. A must have item.
I have not used the tool but bought it for my tool box and to share with others. I saw this tool used by a Mechanic on my plane for a push-rod tube gasket replacement on our Bonanza away from home base. Much Better than the screw driver and rocker cover screw routine many of us have used. Easy to use. It works! Wish I had invented it.
Doesnt seem to work with angle valve Lycomings unless I replace the bolt to press on the valve spring with a much longer one.
Yes, as we have received good reviews from both Continental engine and Lycoming engine customers.
