Rotational gearbox oil quantity

[Mick]

Guys I just posted this in general comments then realized it might have been better here
Does anyone have experience with a PDQ M5? We need to change the oil on the rotational arm gearbox. The ID tag specifies Mobile SHC 630 oil. But we don’t know the quantity needed to fill it. If it helps the gearbox part number is 800024
Thanks

On a 4000 just fill till it comes out the top .
