so there is another one underneath i didnt know that.

Yep, they hid it good.

 You really know your stufff, Exactly as you described it! Opened the drain and nothing. Plugged with a metal like hymen Got some light fence wire pierced it swirled around and drew back and forth 70-80 times and eventually I had about a quart of Weird looking oil and metal approx 1 dimes worth of metal sludge very fine, I used a half gallon plastic milk jug to catch the oil, brake cleaner and gas worked good !  
      I poured in Marcon LV until it flowed out the side level plug and then I plugged it and  poured a couple ounces more I might run it for a bit and then replace it with a fresh batch of Mercon LV equivalent (low viscosity) or try mercon 3
 Thank you!

Your welcome, good to have it all cleaned out now, should work allot better too.

i'll have to flush mine out properly too it was working fine but 50yrs of crud is in there. so you fella's have better results with atf which is around a sae 5 weight oil.
yes they used 30 weight in everything back then as its what they had multigrade oils didnt exist and took yrs to be accepted as superior in most situations and much more convenient.

Unfortunately no change still grinding when I throw the first lever towards the rear, thinking those screws I found in the clutch housing drain I have a place to be..so now I guess I got a pull the pony motor,  About the ring gear grinding, are we talking about the ring gear on the pony motor? 

If you push back on the clutch/brake lever it should stop the pinion gear so it can engage with the flywheel ring gear. If not then the brake discs are worn out.

On my RD4 I have a short bit of water pipe about 12" long sitting over the pilot motor clutch / brake lever, which gives me just that bit extra leverage to stop the pinion spinning so I can engage the pilot.

One of these days I'll pull the pilot motor off and rebuild the pinion clutch and brake plates, but in the meantime, the pilot motor starts easy and runs well, and that tractor only gets driven maybe twice, or 3 times a year, so my Okie fix is buying me plenty of time, because I know if I pull that pilot motor, it will not go back on till I've fully reconditioned the darn thing, and that doesn't make sense right now because it runs so well, and why open a Pandorra's Box that doesn't need openning......

yes those sort of projects snowball real easy!

Still confused as to what kind of grinding you are getting? Video maybe? Pictures showing first lever? I know with my D4 it will grind terrible if I forget to release the pony clutch when the main starts. If I remember the pinion slides right in quietly.
