I'm attempting to search by phone so maybe I'm at a disadvantage. I need to replace a zerk fitting on my BT601 backhoe that goes to my new to me 2013 BX25. The FEL zerks where 1/4-28 but I'm not sure if the BH is the same since reading all kinds of conflicting material. I tried without success to find a parts diagram of the BH and match the zerk part numbers against the FEL zerks but with this phone it's appears to be impossible. So I figure I'd ask here. Thanks in advance!
