Lubricants in my '50 d6 9U6914

There has been quite a bit of discussion about the various oils and grades.
This is what I run:
Everything on a good grade of 30 wt detergent engine oil except the following:
90 wt gear oil in transmission and bevel gear compartment.
Automatic transmission fluid or ISO 32 hydraulic fluid in the pony clutch
(cuts down on clutch drag which helps engagement)
The one place I deviate is the final drives where I run Lubrication Engineers 5250 Almagear. It is a lube specially formulated for heavy shock loading. It is an ISO 1,000 (SAE 250) and it stays in there.

Either kerosene or diesel work fine for flushing.

Thanks OM.
If I understand my Oil Viscosity Chart, ISO#'s, SAE#'s, etc the ISO 1,000 (SAE 250) would be a pretty thick lub oil, right? Say like approx 3 times as thick as 90 wt?
I understand that wt isn't always the big factor, the shear factor or shock load is just as important.
Grease gun grease isn't all the same.
Where you find the Lubrication Engineers 5250 Almagear stuff?
I assume the local oil distributors have their own "model" of oil with similar specs, 76, Texaco, etc.
Other day I was at the Cat House sorta talking about some of this. They seem to want to sell their own brand of 10 wt, 30wt hyd. for some of my stuff, or their 50wt Hyd/Transmission oil for Tranny & finals. I wasn't really sold on them.

BTW, as a tidbit info, this 945 Liebherr excavator calls for Molydag 147/400 oil/grease for the ring/pinion turning gear. From what I can find out 147 & the 400#'s have a lot to do with temp ranges, as well as lot of other rocket science stuff. The Moly part has to do with molybdenum (sp) content, & the Dag seems to have to do with Lithium content. Other stuff I found out is that it is sprayed on under pressurized air system, has a certain drying time, & has to dry/set-up at a certain temp range...anyway, it's big-time hi-dollar stuff$$$.
The above may not be any of the fundamentals at all, but it's sorta how I understand then so far.
For all I know, MolyDag 147/400 may just be Crisco cooking grease😄 😄

They are based in Texas but have some local distributors.
Yes, I'm sure there are other brands/types equivilent but I am not up on the alternatives.
Your guess is about right in the 250 visc. Still pours pretty readily.
Not familiar with Molydag, kind of an odd name but I'm sure the challenge is keeping it stuck to the pinion.

All these lubes are getting pretty expensive. Easy to invest $300 - $500 for complete change outs and that's not looking at the really big guys.

BDF, At the dealer I worked for they always used DA oil & the oil Co. hauled it up from Maryland I believe where their warehouse was then. For a short while then they changed over to a cheaper Drydene brand oil & then Cat came out with their own oils so they switched over to it.We had some terrible problems with Drydene in 8 big natural gas generators in some tech schools here with high carbon build up & other things so we switched back to DA even when we used the Cat oils in the shop & we never had anymore problems with the generator engines with the DA oil in them.

I chatted with a gent who worked on big Gen sets out west and they had a similiar problem with carbon built up and switched to DA and it relieved the problems. He had said that those engines had right at 100000 hours. I could'nt believe it! But those motors are in a different environment running everyday.
