Global Aquarium External powerhead

[bc_slc]

I have a TOP 90 made by global aquarium supply. Though they don't make this pump anymore mine is still working fine. I pretty much run it all the time and it has been making more noise. From what I have read, the motor may need some lubricating. Anyone have some advice as to how to do this?

Thanks,
Mat
