Oil Metering Valve Repair
The repair kit has been packed with all the parts to rebuild your oil metering
valve. The parts may differ in detail from what you have in your valve. This
is due to changes and to the unavailability to the parts over the decades.
1. Disconnect the copper fuel lines from the valve inlet and outlet and
overflow using 2 wrenches, then remove the valve from the mounting
bracket, do not remove the bottom fitting or the overflow fitting from the
valve. Unscrew the two retaining screws holding the valve top to the body.
Note that the valve top and the valve knob are attached.
2. Remove the float from the float pin; remove the needle from the seat
fitting. Using a 5/16ths socket, remove the seats fitting from the valve top
casting; however leave the copper washer in.

behind the inlet fitting. Clean the threaded aperture in the top casting to
remove any dirt or buildup. Perhaps use a pipe cleaner to clean the path from
the inlet hole to the seat fitting aperture.
4. Remove and replace the viton o’ ring on the valve stem, and clean the
stem groove. Clean out the stem guide in the bottom of the valve housing
and the overflow tube.
5. Clean the inside of the valve housing castings, top and bottom. Replace
oil inlet screen with new and replace the inlet fitting into the top casting (use
teflon tape and do not over tighten).
6. In 02-000 kit only, place the small adaptor in over the copper washer and
place the new copper/brass washer over the adaptor, then screw in the new
seat into the top casting until tight but not so tight as to damage the
aluminum threads of the casting (35 inch pounds).
7. Place the new needle in the seat and slide the new float on so the flat
bracket groove catches the neck of the needle.
8. Insert the float hinge pin and test the movement of the float up and down
and that it moves the needle up and down in the fitting. (When held upside-
