Oil for Transmission Gearbox
Posted: Wed Jun 12, 2019 11:03 am
Hello,
I'm sorry to ask for a question which has been already discussed many times, but I'm still confused
I need to refill my 741 Gearbox (BT6 transmission) and looking on forum the only brand mentionned is the Swepco 201 which is not distributed in France ... In the workshop manual it is written "SAE 90 HD Hypoid", and looking for such on the web available in France, could you confirm if one or the other will be OK :
- Castrol EP90 (Mineral, SAE 90, API GL4) : Castrol EP 90 is recommended for the lubrication of conventional spiral bevel final drives and mild hypoid axles where API GL-4 oils are recommended. It may also be used to lubricate spur and helical gears and for other applications where the manufacturer specifies the use of an oil meeting API GL-4. It should not be used in high off-set hypoid axles where API GL-5 oils are typically recommended or in axles with limited slip differentials
- MOTUL ALLGEAR EPL 90 (SAE 90, API GL4 – MIL-L 2105) "Mineral lubricant for mechanical transmission, synchronised or not synchronised gearboxes, gearbox/differential, transfer gearbox and hypoid differentials without limited slip system operating where a SAE 90 grade is recommended by the manufacturer."
- MOTUL GEARBOX 80W-90 (Mineral, 80W90, API GL-4/GL-5) : "Mineral lubricant reinforced with Molybdenum bisulphide to handle heavy loads and reduce transmission noise. All mechanical transmission, synchronised or not synchronised gearboxes, gearbox/differential, transfer gearbox and hypoid differentials without limited slip system operating under shocks, heavy loads and low revolution speed or moderate loads and high revolution speed. Very high lubricating power decreases friction and wear. SAE 90 grade at hot temperature to provide outstanding oil film resistance at hot temperature."
Thank you for your advises
