Question for those using the oil filter that fits on pto opening. Curious of those using it, if and when you check it, do you find any metal or brass on the metal near filter. I checked mine soon after rebuild and after several thousand miles, and find brass dust on the metal. It's hard to tell whats in filter it self. My trans seems to be getting noisier, growls more in 1 an 2 idling around and sandy sound in bearings at speeds. Oil was clean other than fine brass by filter. Or maybe noise, is do to radio quit working?
