I recently purchased a BH77 for my L3901. I have 1 pine that barely takes grease. A few pumps and I can not get anymore in I took the zerk out it is good. I took the pin out and it appear that when I grease it that grease comes out of the little hole in the center. I can not get grease down to the far end. I s the hole supposed to gall all the way and another hole drilled in the far end. My dealer is clueless and dosen't want to get me a new pin. Has anyone else had this issue
