The history of Lister in Argentina dates back to the 1940s, the 6/1 and another smaller one for shearers were already imported from England. Later, for some reason, they began to be manufactured locally, I suppose under license and under strict quality standards ordered by Lister, who achieved engines of exceptional quality. Likewise, the most durable was the 6/1, followed by the 8/1 SOM, and finally the 16/2. The 6/1 was the engine used to generate and for pumps, all the 8/1s I knew were electric generators. Here there was no culture of maintenance... the engine worked until it detonated for various reasons, generally connecting rod breakage due to bearing wear, and also failures in the speed control (governor) and also quite a few cases of crankshaft cutting, mainly in the 16/2, which caused a bad reputation for those engines, when the truth is that this usually happened after a careless repair .Regards.
