Norton owners using (140 wt?) redline heavy shock proof gear oil report reduced (or no) wear on the gears. This is great but the oil is so thick that in some cases it might not flow into the bronze bushings and starve lubrication to the shafts.

So I've been mixing it with synthetic 75-90 wt and or quality 90 wt gear oil to reduce the viscosity - adding a little more film protection to reduce gear teeth wear while still providing lube to the shafts and bronze sleeves. 1/3 to 1/2 shock proof by volume seems to work well so far.

How about using the lightweight shock proof oil? The blue stuff. It made my BMW R60/2 shift quite a bit better.
 
I use the Redline lightweight shockproof in the Norton. I found that if you shake or stir it before pouring it becomes much thicker and looks more like green. The heavy parts settle to the bottom of the jug almost like a grease and the blue floats on top. Hopefully the gears can quickly whip up the mix again every time the bike is used. I think there is plenty of agitation going on in there. I like it because it sticks to the parts above the oil fill line so they don't rust. There was a more recent posting on here advising not to use it but I can't remember what the reasoning was.
 
I use the heavy in all machines for years no issues BSA A65 Triumph T120 Commando 68 MGB would use it in my 1939 Farmall F30 if I could afford to buy 10 gallons of it for rear end and gearbox
 
I run the red stuff. Sticks like glue. Love it. Helps the clutch actuating lever and cable end and some nuts in the outer that would otherwise receive no lube at all.

Interesting kit the Farmall, would imagine it to be pretty tough

The heavy red shock proof may be fine - I have not confirmed that its too thick to lube the bronze sleeves. But I heard that it can be too thick for the sleeves.
 
I'm overhauling my gearbox now. It was overhauled before the 2012 season. Close ratio set from RGM. After nine years and 16,000 km, gears are worn out. Last two years and 7557 km with Red Line Ligthweigth. Before this I used ordinary 80W-90 gear oil of reputable brands.
The amount of metal shavings increased dramatically last year. Coincidence, I don't know. But think I'd try ATF F after Comnoz's earlier statements.

not hard to turn at all you have to start with a hand crank which takes some muscle..especially in cool weather the guy in the blue shirt is who i got it from (Beatty). when he was a teenager he went with his father to the auction when we sold the farm equipment off after my grandfather died in 1971. the beattys used it on their farm til his father died about 1980 then parked it it had sat there in a shed for 38 years until by sheer chance Beatty and i started talking in a store and he said he still had the 'old tractor' I went to his place and looked at it I remembered it from when i was a kid and would go to my grandfather's farm (it had been in our family since 1830). after a brief negotiation I bought the tractor for $1500 and had it hauled to my house. I spent about $1000 on tires, carb rebuild kit, magneto points, and manifold. it has 21 grease fittings.. rather than make it all shiny I power washed it and then soaked the whole thing with WD40 to preserve patina. here are a couple more pics
