Important:
When changing valve springs while the heads are still
in the engine you MUST ensure the valves do not
drop into the cylinder. This can be done a few ways.
1) Use compressed air to fill the cylinder and
hold up the valve.
2) Ensure the piston is at TDC so the valve can
not fall into the cylinder.

4) Install the Comp Cams Valve Spring Removal Tool on the cylinder that you wish to remove the
valve springs from. Place the tool over the rocker mounting studs. Tighten the included rocker
arm Polylocks to hold the tool firmly in place.
5) Make sure that the valve can not fall into the
cylinder, see important note above.
6) Place the H-beam over the valve springs ensuring
the valve stems and locks are centered with the
window on the compressor facing up.
7) Thread in the included M10-1.5 65mm bolt
through the arm and seat it in the receiver cup on
the top of the H-beam. (See picture)
