rodney Posted May 17, 2013 Report Posted May 17, 2013 My 65 E has no lower air vents for the rear seat passengers. These are the heat vents in the side panels, not the overhead ones. The scat tubing is in place on both sides, which comes from under the dash, is 1.25 in diameter and ends behind the side panels. Apparently the last time the interior was done and side panels replaced they were not hooked up and are now blowing air into the space between side panel and outside skin. I want to add the vents back, to give my kids at least a little heat back there if possible. What did these vents look like initially? I am considering adding eyeball vents to side panels but none fit the 1.25 inch scat and I will likely need to fashion a reducer of some kind. Not sure what these looked like initially. What do the outlets look like in others planes? Thanks in advance for any insight here. Rodney Quote
clh Posted May 17, 2013 Report Posted May 17, 2013 on my 64 E, they have a short little piece of aluminium tube on the end where it extends out a hole in the bottom of the side panel. Another piece extends into the baggage compartment... Quote
Bob_Belville Posted May 17, 2013 Report Posted May 17, 2013 I have a '66E so I assume yours is similar. Smaller dia SCAT hose runs behind side panels, down low, below door, etc. I'll guess it is 1", It has to be crushed a little to get side panels to fit against outer panel in some places. This pic should help... I'll look around to see if I have a pic of the outlet in the rear seat side panel. Quote
Bob_Belville Posted May 17, 2013 Report Posted May 17, 2013 I did not find a pic of the outlet but here's a close up of the plumbing at the pilot side. The right hose goes to windshield, the left to the rear seats. (The other pic is for anyone who wondered if we were able to put the plane back together after seeing the first pic. ) Quote
Bob_Belville Posted May 17, 2013 Report Posted May 17, 2013 clh, I think the baggage vents are cabin exhaust, but I could be wrong. Mine are plumbed to the outside vent shown in this pic above the wing. Quote
clh Posted May 17, 2013 Report Posted May 17, 2013 clh, I think the baggage vents are cabin exhaust, but I could be wrong. Mine are plumbed to the outside vent shown in this pic above the wing. The cabin exhaust is on the top near the hat rack. This is a tube that comes out just behind the rear seats. it is "T"ed to the heater scat hose. I found it a little strange... Also, I don't have the vents on the side of the fuselage like you do. The vent is on the top about 2 ft behind the inlet vent. Quote
Bob_Belville Posted May 17, 2013 Report Posted May 17, 2013 clh, interesting. Yours is 64. Mooney had made a change by the time my 66 was built. Rodney's is 65 so it could be either. I guess your plumbing runs over the spar beside the rear seat? Quote
rodney Posted May 17, 2013 Author Report Posted May 17, 2013 Thanks guys.. This is fascinating. I do not have the side vents like Bob on my 65. I do have a exhaust vent from hat rack to top of fuselage. I am not sure if it has a tee. I do have 1.25 inch scat from down low on each side, but on the door side, there is a tee, right under the door. Nothing connected to 2 of outlets of the tee. No tee on pilot side. I was wondering why the tee was there and it didn't occur to me this could go all the way to top of hat rack to the exhaust. The tubing is long gone if it was ever there. What purpose would this serve? I might have to look at hat rack exhaust now to satisfy my curiosity. Rodney Quote
clh Posted May 17, 2013 Report Posted May 17, 2013 On mine after the tee one branch comes out in the footwell of the back seat. the other comes out on the baggage compartment floor just behind the rear seatback. The only function I can see of the "baggage warmer" is to keep stuff from freezing? The exhaust vent is on top of the hat rack is completely separate system. They must have changed it sometime in late 65 or 66. Quote

Bob_Belville Posted May 18, 2013 Report Posted May 18, 2013 HMR - YOUI think it's scary? That's the shot the avionics shop sent ME about 1 week into the panel upgrade! Note I also posted an "after" shot in a later post. 1 Quote
1964-M20E Posted May 21, 2013 Report Posted May 21, 2013 On mys former 64E model the back vents were not much more than a hole in the side panel and a plastic trim ring and a short aluminum tube poking through connected to the scat hose to the front Quote

Bob_Belville Posted May 21, 2013 Report Posted May 21, 2013 Hey B-26, that looks like a partial panel, with a yoke and a power quadrant it's almost airworthy. Quote
