Setting Your Expanding Pilot

1. Select an expanding pilot that is the same diameter as the valve guide ID.
2. Insert the pilot into the valve guide, making sure the expanding section of the pilot (collet) is completely within the valve guide. The pilot will not center properly and may be damaged if the collet extends outside of the valve guide.
3. Pilot shoulder should be about 1/8" above the valve guide.
4. Turn the pilot while holding the nut at the opposite end. This will expand the collet and secure the pilot into position.

NOTE: DO NOT use Expanding Pilots with multi-angle valve seat cutting systems such as 3-D Fast Cut.
