All of these letters and numbers can get confusing. Is it really necessary to know what each of these specifications means?
Axles, differentials, final drives and other gear sets used in mobile equipment applications all require specific lubricants designed for the heavy loads and the sliding and rolling forces associated with the operation of gears. All gear lubricants are definitely not the same.
Different industry associations and different equipment manufacturers issue unique specifications. Most of the time, these specifications are not interchangeable. Substitutions of one type of gear oil for another can sometimes be done, but these substitutions can be tricky and you should use the guidance of a lubrication specialist to help you make the right decision.
For these reasons, it is important for equipment owners, operators and lubrication technicians to identify which specification is recommended by the equipment manufacturer for each machine and each gear set to ensure that the correct lubricant is being used. Who is right? I liked ATF as its easy to spot leaks red and the thinner lube must release a little power with lower churning losses, it also must find its way into the bushes in the sleeve gear easier than thicker oil.
Its a very sturdy box ,lube type not critical , just fit a breather to inhibit rust. They only recommended the oils available at the time, BSA recommended the same oils in the 50's and by end 60's they had changed to EP90 which was developed in the mid 60's, which has the same viscosity as a straight 50W engine oil.
Haynes followed the same path using Castrol recommended oils as they had a tie up. I've read that some modern transmission oils are mean to yellow metal. The data sheet for that oil says it don't harm yellow metal. So I use it in AMC boxes too. The original EP oils contained sulphur based additives which attacked bronze bushes but they have nearly all been reformulated, regardless the Glacier Bearing Engineers manual tells you the effect only happens above C.
Annas statement to 'never use aEP oil as this desoloves bronze in time' contradicts her statement that her norton manual says use hipoly 80 castor this must be meant to say Hypoid 80 Castrol which is an EP80 oil. After about 30K miles my gearbox bush set were all worn enough to need replacement, Sleeve gear bushes were the worst. I decided that the oil was not getting thrown around enough and did not have an easy path to the bushes.
To this end I went for the thinnest EP oil I could get.
