Hi,
As you said, lube oil in the gearbox is getting contaminated within short duration and average Gearbox replacement period or change of internal comes in 18-24 months cycle.
Installed Gearbox is having shaft driven lubrication pump at the input which is feeding to all the bearing internally except one of the output shaft bearing which is grease lubricated.
Reference to the filtration system indicated by you,
Dose it require individually for all the gearboxes or what is the type of arrangement?
regards
