Just as the title states....
When I was dressing my new motor I noticed these 'reverse' flaps. But have no idea what cable would hook up to the flapper arm, or where it would come from? Or what would activate it? Someone please enlighten me... |

the flaps are "cooling" flaps that divert air over the cylinder heads for .... well..... cooling. (IMG:style_emoticons/default/biggrin.gif) the flaps are spring "loaded" such that if the arrangement fails, then the flaps are in a default cooling mode for safety sake. the flaps are operated by a cable that runs vertically upward beside the engine up through a small hole in the tin. there is a place for a screw and nut to clamp the cable on the rod (the spring loaded rod that the flaps are attached to). the cable is attached to a bellows like piece located under the engine that is the thermostat. when the thermostat gets warm, the bellows expands and the cable is .... relaxed (?).... and the flaps move to the warm engine cooling position. when the thermostat gets cold, it contracts and pulls the cable to open the cooling flaps to the cold engine position.
where is Dave Darling when you need something explained? (IMG:style_emoticons/default/rolleyes.gif) (IMG:style_emoticons/default/laugh.gif) |
