Subject: Re: Smiths rev counter drive off of Rotax AT146 dynamo?
Hi Ted,
Just to add confirmation. My version of this engine is the sanction 4 type, in my LG6, so even more recent! The large threaded hole in Adrian's final photo is also where my rev counter drive emerges; your photos show that you have a circular plug with four dimples for removal by a pin-drive spanner in that location. Note that on Adrian's and my engine, there is a threaded boss for a bolt to presumably lock the brass drive adaptor in place.
Your mystery component appears to include a tap handle. I would opine that it is for a water take-off, perhaps for a heater? Is this engine original to your car? If not, be aware that these Meadows engines were used in many other applications, eg buses, tanks, marine. Whilst the basic engine would be the same, there would be differences incorporated specific to the intended application. Such engines were available, sometimes still unused and crated, until fairly recently, and were a ready and cheap alternative to rebuilding an original engine. Alternatively, parts from such engines could be incorporated as part of a rebuild. or example, I've discovered that the water pump on my engine is actually the marine version, with a bronze cover plate.
