1. Open the valve by turning both knobs four counterclockwise
turns.
2. Withdraw the two Phillips head screws on the upper part of the
valve body and remove the cover.
3. Remove the roughing screw (10). Lubricate its threads and the
spherical socket.
4. Insert the two Phillips head screws that held the cover into the
two pivot rods and, using the screws as handles, pull out the
rods.
5. Lift out the handle. Its sides have been sprayed with a
semipermanent coat of molybdenum-disulphide. The lubricant in
most cases will not require replenishing. If the user judges that
re-lubrication is necessary, a small amount of Fel-Pro C-100
should be applied to each side of the handle where it guides in
the body.
6. Remove the rod assembly and lubricate both ends. Replace it.
7. Lubricate the pivot rod holes in the handle. Do not lubricate the
pivot rod holes in the body.
8. Reassemble the handle and pivot rods.
9. Replace the roughing screw, valve cover, and two small screws.
10. Follow the procedure specified in para. “Adjustment of handle
position” to close the valve and adjust the drive mechanism for
proper operation.
