Oil for Blackstone boxes?

[Rufford]

I presume its EP80-90 oil that goes in a Blackstone gearbox, can anyone confirm this or point me in the right direction?

" . . or point me in the right direction?"

 

Well it will be forward or reverse. Don't know, but someone will. The Parsons took engine oil, and had a clutch full of metal plates so EP might not have suited that. Might try emailing this fellow - Michael Key - email addy in the link:

The main gearbox is fed via the engine oil pump and thusly shares a common sump with the engine itself. The reduction box however should be quite happy with EP90 gear oil.

[Laurence Hogg]

10-30 for engine / gearbox according to handbook

The reduction box doesn't need oil with the EP rating as there are no bevel gears in there. Morris Lubricants do an SAE 90 gear oil, which is what I use.
