I would think it would be closer to 1968 like the machine I'm working with. I'm not talking about today's machines.

So I'm home and have snap a photo of the book and the spec grid for the final drive lube spec but don't know how to get the photos into a reply.
Any help with that would be appreciated.

I circled the button in green…once you select up to four pics…
then you pick thumbnail or full photo to post…
I bet our admins have prefs on which you/we post.

As near as I can tell the book was printed 10/70 not sure of that but there isn't any other numbers in the back of the book.

Oil technology has come a long way since the book was printed.
Since I just did a final drive up and now I know FD01 oil exists, and even though it is probably 70% more expensive then the other generic gear or TDTO oils. Next oil change I am going to use it. The oil is not even the cost of one bearing.

I know it probably won't apply in your QLD climate but just be aware that a lot of the newer generation machines that use FD-1/FDAO oils in rear ends are performance-limited by the on-board electronic systems until the oil warms up to over something like 65 DegC in an attempt to prevent issues regarding lack of lubrication when the oil is cold.

I wonder how long it will be until the technology allows machines to have constant oil sampling done onboard.

The ideas have been around for awhile. There is a company advertising field analysis kits available now.

Probably another set of fault codes someone would have to worry about.
The thought is producing monitoring based on fuel usage and not just operational run time. Fuel usage and load factors are already being tracked and used in the valuation process for used machinery by some dealers and manufacturers.

We use 80w-90 in our gearboxes. Heavier weight oils might be "better", but you also need higher temperatures for them to flow as well. Up here in Canada, I'd only consider it as a summertime-only lubricant.
The only place I've seen 140w gear oil being used is in Radicon worm gear reducers.

Thanks for chiming in, I take everyone's opinion seriously If I even thought about using the machine in the cooler/colder times of the year I would have went with a lighter synthetic oil.
My tractor will only be used in the summer months, if I for some reason decide I'm going to use it below 32*degrees I'll dump it and go to a lighter grade, for now it's in there.

Personally, I don't think it's a bad choice, after all, for a splash-lubricated system like how these final drives are set up, I think everything will be getting plenty of oil.
Just keep the operating properties of the oil in mind, and I think you will be fine.
