X.9090 X.9060 We should be glad if you could send us models of the moving parts of the EAC. valve gear namely, valve, valve and tappet springs, washers, rocker, push rod, tappet, tappet roller, etc. We have not yet handled these parts in the flesh and it is very important to know that every ounce of superfluous metal has been removed. Have we used the tubular push rods or the solid push rods in our tests? E.{Mr Elliott - Chief Engineer} | ||
