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

.  

 
3. Remove the fuel inlet fitting only and clean or replace the stainless screen 
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 905005 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.
