Hello to all who have helped me with this project . @emerygt350 ,@TJB/914, @Superhawk996 , @ChrisFoley , @rjames , @MDTerp
I am in the middle of rebuilding my MPS and have a couple of comments and questions . First when I opened up the unit I found the most difficult job was removing the rivets holding the two halves together. When I removed the retainer plate to take out the old diaphragm it was in two pieces .  I needed to take two measurements since I was replacing the stop screw , I needed to measure the the stop screw protrusion into the housing . The instruction sheet sent to me by a member had the measurements he must have made when rebuilding his MPS . His stop screw protrusion was 1.97mm and mine only measured 1.72mm. His inner/outer screw assembly depth in the old diaphragm measured 6.51mm . Here's one of my questions ? when I measured mine I got two measurements depth to inner/outer screw assembly was 4.03 and depth to the washer outside the inner/outer screw assembly was 5.46mm. Again there is a difference and since mine was never accessed before (epoxy over screw was not disturbed) is the difference in measurements ok and which measurement should I use I will try to attach a photo or two to help with my question. this one .  I have not touched either of these measurements yet and awaiting any help/comments. I think it's this one to the washer on diaphragm .  |

Thank you Superhawk and emery ,You are correct in all you wrote I did a bit of squirreling today . I should have verified all the points you made . I basically need to pull back and start over but at this point I am beating myself up a bit as I should have known better . I will start correcting all these points next week when my head is clear and I have the time to commit to correcting my mistakes . When things went bad today I made a few bad choices . I should have asked about the CHT install since I was not well informed . I really screwed this one up today .
Thanks in advance for the questions coming next week . |
