Here is the dlc coated finger follower as mentioned - the cam lobe runs on the back of the finger follower - the left hand side of part,
So I got a bit of time to start a test rig for the Pneumatic Valve Spring assembly. I want to do a little bit of testing on it in terms of pressures and so on so a little fixture was required.
Luckily its an easy rig to make with Part 1 shown below, offcut of 6082-T6 and away we go -
Adding seat angles,
Fitting the valve guide,
Drilling the holes to bolt on the Pneumatic Valve Spring assembly, plus the air feed hole. The air hole just .75mm in diameter,
Adding the counter-bored face and hole for banjo air fitting,
Slots in sides to lighten and allow visibility,
And that's Part 1 of the test rig done.
