D2 3J Pony clutch question

Figured I'd post a picture, not to recent, but not to old either, the old D2 is up and running now, just fine tuning it a little here and there...

all the poney cluchs are wet

If you're having trouble with a "sticky" pinion clutch, drain the oil and refill with diesel and run it a bit then drain and refill with ATF. In colder climates the recommended 30 wt engine oil is a bit thick and the ATF seems to solve this problem.

Mine doesn't have a drop of anything in it, and doesn't look like it has for some time, thats why I was wondering if there were any dry pinion clutches ever used on these tractors. I'll probably add ATF and call it good, or are there other suggestions?

Thanks,
