Sorry I’m out of the farm and for some reason every image I post exceeds size limit

mine has a little Oiler About an inch in diameter with a brass flip cap and Two bolts on each side..on it it’s filling channel it is the size of a small straw..
does that mean I have a wet clutch? I Also I have a plug on the bottom of the bell housing that’s about 3/4 so if anybody can tell me if I just drain it and let it be or put the 70% of the quart I drained out that would be awesome. Also some weird little screws came out they’re the kind That look like a small bolt thread with a flathead screwdriver channel cut in the top and a tiny cone on the bottom I’ll try to post pictures later thank you in advance!

Only if you oil it too much, you'll have an oil clutch, that oil cap is for the sliding collar on the clutch. Those screws are from the clutch brake, they hold the lining on.

It should be a dry cluch and the wet cluch have a deep stick for check oil level.

Thank you! How many of the screws are there, I wonder if somebody just lost them and used  new ones..
When I do oil that collar how much 30 weigh should I use just like 10 drops or something? 

The clutch was working great didn’t seem like it was sleeping at all, I stalled it out a couple times Trying to push too much dirt
Accidentally drained it thinking it was the transmission but I’m glad I did, I know now that oil seeps in there from the transmission and knowing is half the battle!

For the J model D2, it calls for filling the cup with transmission oil every 20 hours of use, and on the U model it says to fill every 10 hours of use, cup should be mostly filled with felt or similar packing to hold the oil.

Thanks Josh on point!

The filling cup for the transmission on my D2 does not have any kind of felt or anything, and I don't recall any such filler on my old D4. I never realized they were supposed to have something in there to retain some oil to slow down its dripping to lubricate the collar. Any recommendations on what to stuff into the cup for that purpose?

30w? 

Ok, I believe those are adjustment screws from the pinion latches, part #3B5121

They must need some purple thread locker or red? Apparently they Are not super necessary as my clutch seems to be working fine? Who knows I guess I got a pull the cover and look around
