JIMS, breather reamer tool - 36-99 B.T. (excl. Twin Cam) (NU) 537557 Note that the black paintUsed to repair the (often damaged by OEM plastic breather valves) breather hole. No need to disassemble the cases. This tool will ream the hole to +. 030" so a replacement steel +. 030" JIMS or S&S breather can be installed. Note: After the reaming process all aluminum reaming chips must be removed. Also, when working on early 36 69 cases, before reaming check if wall thickness in the breather hole is thick enough so the reamer will not break through.
