shaft seal cavity in the compressor housing. Apply clean compressor oil to the shaft seal seating area on input shaft.

8.Lubricate the inside area of the rotating seal with clean compressor lubricating oil, do not wipe or touch the face of the rotating portion of the seal. Align the slot in the rotating seal with the drive pin on the compressor input shaft, see Figure 5-30. Carefully push the seal on, holding onto the out- side area of the seal until the seal seats against the shoulder on the input shaft. Make sure the seal is seated against the shoulder. If the seal is not fully seated against the shoulder, the shaft seal carbon will be damaged when the seal cover is installed.
