When I pulled the belt pulley off the 70 I noticed moisture in the oil so I know it needs drained and replaced and the '48 A I recently picked up
has a noticeable noise when you disengage the clutch pulley so I want to try replacing the transmission oil on it and probably my 50 while I'm at
it. My operators manuals call for 90 weight in the 70 and 140 in the A if I understand it right. Is there one oil I can use in all three or should I
stick with what my manuals tell me? Also any feedback on the noisy A transmission would be welcomed. It's not a violent noise but noticeably
louder when disengaged. Not sure how to describe the sound?
