I was concerned about having dislodged the bearing seals on my spindles by over-greasing my Scag Cougar spindles. I wrote to Scag, and they said over-greasing damage to the bearing seal is unlikely, because Scag spindles have a pressure relief fitting precisely to protect against over-greasing damage. Here is the correspondence: Reply from Scag Thank you for contacting us with your question. Your thoughts in regards to the purpose and operation of the grease relief fittings on your spindles is absolutely correct. They serve as a pressure relief to prevent damage to the bearing seals due to over-greasing. I doubt very much that you have anything to be concerned with. Thank you again for your question. I hope that this information will be helpful to you.

I assume that the manner of greasing the spindles would be to grease till a bit comes out of the relief fitting (I assume this because I just greased it for the first time and the area around the relief fitting is where I see the grease come out. How's that relief fitting work? Does the grease come out of the center of the fitting, like a one way valve? Will this relief fitting save one from over-greasing and thereby dislodging the bearing seals? I ask this because I didn't see in time, the grease ooze out on the first spindle I greased, and I over greased it till I discovered a glob the size of a golf ball by the relief fitting side that was hidden to my view by the LH belt cover. I hope I didn't screw up the bearing seals. What do you think?
