Differential rebuild in cold weather

I will soon start the rebuild on my Case W3 (530) tractor differential rebuild with new bearings and races. Unfortunately I am in the transition of building a new shop so have tractor split apart on sheets of plywood under a pole tent. Its been this way since early summer and I will finally have all the new parts for assembly. A buddy told me to coat all the bearings\races with Lubriplate 105. I am keeping everything undercover yet I am sure condensation and moisture is going to get in here and there. I have new carrier housing shims and after final assembly my plan was to seal the outside edges with a sealer so moisture would not rust them. A thought was to wipe them down with WD40 upon final assembly. So when doing service out in the field in changing temperature\humidity what precautions should I take? Is there an additive to gear oil you can use to extract water out of your differential case during an oil change? I been thinking of waiting till 2018 late spring to rebuild it yet my wife would like to the tractor back together sooner than later. Any suggestions will be appreciated. Thank you in advance.
 
Oil will float on top of water, any moisture, if it's been sitting, will be at the bottom. If you'll
running the tractor condensation etc will evaporate with friction heat generated
 
Your way over thinking this, do the
work, spray it down with oil and put it
together and run it. Tractors sit in the
fields and changing temperature all the
time, gearboxes are vented so
condensation forms of course, and then
when it gets run and warms up it
evaporates.

Thank you. I feel better already!
 
(quoted from post at 02:30:54 10/19/17) BTW cancel the WD40. It's silicone based and won't play nice with gear oil.

I agree there are a lot better spray lubricants out there than WD40.
 
Ditto on dumping the WD40. I refinished an old shotgun years ago and sprayed it down with WD40 because I was leaving it in my well house. Couple of weeks later, it was solid rust! Almost destroyed it. Still a few minor pits in the barrel after another refinish. I would just coat everything in good oil.

Wd40 makes a special spray can for preventing rust, leaves a minimal film and works great I use it in my press brake tooling since it resides in and open shed

Thank you. I'll research that in the meantime.
