When my father-in-law’s early 1960s Japanese-made Model 101 Over/Under (#76774) would not shoot, I found that the selector switch was stuck midway between everything and would not budge. May have been the WD-40 overdose applied before he stored it away.
A small drop of oil worked under the switch freed it up enough to move fore and aft and right to left. When it jams up again, a slight twist of the switch frees it up again. Wait and see if use continues to limber it up or pull the stock and clean it? If I tear it down, do I apply a thin film of oil to the parts?
Since the ejectors were also sticking, I searched for suggestions and found that the online Winchester manual now recommends lgrease on some parts and oil elsewhere (Fig 6 and 7 below). Where I am confused is that my F-I-L’s gun is different. In Fig 6, points A are not found in his gun. Points B appears to be a rod that is also not found. The ejector slides and related parts in his gun also differ from Fig 7. Should I apply some light grease to the trunnions and pins?
Anyone have the instructions for the Japanese Model 101?
Boy, the pictures sure look worse here than in person.
Any suggestions appreciated.

I’d suggest a good cleaning. Some oils attract dust, dirt and grime and some folks feel WD-40 gets gummy over time. WD-40 is a marginal lubricant at best but very good for some applications. I prefer CLP or other gun oils, I use a light gun grease in places that operate under pressure, like the trunnions and pins you mentioned. I’m not a gunsmith but I know after decades of dealing with dirty guns (all my favorite guns get dirty as often as possible!) the first thing to do with a malfunctioning gun is give it a good cleaning. Broken or badly worn parts will be revealed during this cleaning but usually a cleaning is all it needs.

Many thanks for the suggestion. Used Hoppe’s on it since I started using it. Probably need to pull the stock and clean the Selector Switch.
