Recently replaced a leaking bearing assembly on my Armstrong S-25 pump. The previous one required oiling, the new one is the permanently lubricated MF/BF model. I look forward to not having to lubricate the bearing assembly, but what about the motor? The original manual that came with the pump indicates that the motor has oil cups that must be lubricated at the start of each season. However I don't see the cups, nor any inlets to add oil to. How would I go about lubricating the motor?
