So awhile ago, I asked about why my 160 mower was leaking oil past the seal, and people said to check the pressure relief fitting... So thanks to folks on the forum and social media, I was able to figure out that there was a relief fitting on the back of the gearbox. When I pulled the old fitting out, it was completely frozen, but I did find a "5" stamped in the top. So I found out that if I ordered a 1/8-27 NPT grease relief fitting 1-5 PSI, it also comes stamped with a "5", so I am hoping it is the proper replacement part. I installed it today, topped her off with gear oil, and went out and mowed for a solid hour. No new leaking that I could tell, so we're off to a good start!
