M14 oil/taps etc
- The crank shaft position indicator concept came from Sergio Dallan in Italy. For a while he sold a kit combining that with an oil tap, very similar to the Kimball's. In it's final version the access to the tap goes through a small door on the side of the engine cowling, and an additional safety factor was a "barbers pole" protruding through the top of the cowling, when the tap is shut.
- Vedeneyev themselves came up with an ingenious (and very simple) solution to oil in the in-take tubes. It has similar drains, but rather than dripping outside or into cans, the system was fully automatic, draining intake tube oil into a one litre container mounted as part of the engine. After start up, a separate pipe slowly took the oil from the tank through manifold vacuum and into the cylinders. An additional advantage is the extra oil provided on start up. It had a series of small check valves which automatically shut the system off during normal running. It worked well, but Vedeneyev are desperately conservative, and would not sell it because it is not certificated, and in Europe we cannot use stuff that is not.
- In passing we have just received the first two of ten M9F (430hp) engines from the Veronezh Mechanical Plant, as used by the Russian Team Su-26M3's.
