Farmall B rocker arm oiler stud question

I have an odd question. Can anyone tell me if there is supposed to be a lockwasher on the oiler stud that holds the rocker arm assembly down? I was checking head torque this weekend, so I had to take it off. When I put it back on, I started it, and watched the rockers start dripping. But I also noticed oil oozing out of the lockwasher, since, obviously, the washer is split. This got me wondering if my dad stuck that on there years ago when he last serviced it. I took it off, and there is a noticeable difference in quantity of oil reaching the rockers - it went from a slow drip of oil, to a steady drip. But now I'm worried the stud will come loose with the lockwasher removed...

Does anyone have access to the service manual with parts diagrams to confirm? I used to have the PDFs somewhere, but I can't find them.

Thanks for any input!
 
The parts book does not show a washer being used on the center (oil) stud. It should be torqued to 30 foot-pounds, that will keep it from coming loose. The outer pedestal studs should be torqued to 25 foot-pounds...
