Indeed. S&S have been around a LONG time. I loved the 52300. I hated the Electro/Hyd governor system. The Selenium Rectifier in the DC charging system was also a problem. Failed often, and when it did, it was a health problem. smells like rotten eggs, and is poisonous. This picture is NOT a representation of the one on the gen set. The one on the set weighed about 5-6 pounds, and you could have beat a rhino to death with it.
The DC charging system regulator, was another trouble spot, It was, I was told, the same as what was installed in the M113 track. High failure rate. Could be adjusted through a small hole in the top, with a tiny screwdriver.
The AC Volt Regulator was also a part that was good to have several on hand. It used 4 small glass tubes, that we always kept in a drawer. If new tubes did not help the AC reg problem, then the whole thing went into the trash.
The rest of the set was very solid.
