[EXPLAINED] Starting air distributor maintenance! MAN B&W

[@manuel04309]

I wish you had continued the video explaining more about the astern movement. In the astern movement, the air would enter from the lowest port of the Valve. That is understood, but how does that change the direction of rotation, of the distributor? Which Pilot Valve will receive the air first? the pilot valve on the negative part of cam or positive?

[@HtoonPyeat]

Thanks for your comment! The pilot valve which can go outwards first makes the rotation.

[@manuel04309]

@@HtoonPyeat thanks so much for your prompt response sir. Would you know which pilot valve would go outwards first, sir?
The one whose roller is on the negative part of cam, or positive part?

In Astern , which type of Alarm or problem you faced. Please explain briefly. Thanks.

[@HtoonPyeat]

There was an astern fail alarm with no starting air because the related astern pilot valve was sticking. So, we tried Ahead air for a short period to rotate the camshaft . Then, it was possible to run in astern because the cam position was changed.

Please watch 03:29 of the video. You can see No.6 pilot valve will move outward at the outer cam profile
