It has a clear sight window with oil fill marks so you can monitor lubricant level, and a side fill plug for adding oil without removing the cap. The cap threads directly onto 6-1/4-inch x 8 UN(M) hubs and includes an O-ring seal. Replace it if the window is cracked, the threads are stripped, or the side plug is leaking.
