It will reside in an unheated attached garage that rarely gets down to even 40 degrees so I think I'll stick with straight 30wt.Agree with Sheldon on straight 30wt unless you are storing it and starting it in an unheated space; I would not want to startup a Magnum filled with 30wt in sub-freezing temps. Otherwise stay away from the multi-weight oils in these engines if you can. I use Rotella SAE30 year-round in the motor and transaxle (yes you should drain and refill the transaxle oil too). My tractor spends the winter in an unheated but attached garage so it's never being started much below 40*.
I will grease everything according to the manual today and should be able to get to the clutch splines tomorrow afternoon. Do you guys have a preferred grease? My dad gave me a few tubes of Redline CV-2 synthetic grease. It's got "Red Moly" in it... whatever the heck that is? See attached pics. I think he said they used it to pack cv joints in some of their high performance race cars. I'd like to use it just because I have it but it may not be a good application for the Gravely? If there does seem to be a preferred grease i can run out and buy a few tubes this afternoon.
Also... a bit off topic but the guy I bought it from had three cans of original Gravely paint in the big pile of stuff that came along with it. I thought maybe someone might find the part numbers useful? I'd guess that the newer of the three cans was purchased for the 16G. The two older cans are probably way older... I think the guy owned an 816 before the 16G so they were probably meant for that. The fact that they still have lead in them must date them back a ways...
