chrixxer Posted June 4, 2017 Report Posted June 4, 2017 (a) What should I use to replace radio cowling screws? I have a couple with stripped heads. (b) Is replacing the captive screws on the engine cowling easy? What part(s)? (Several have rusty heads.) For a '66 M20E. Thanks! (P.S. I'll do it, if necessary, under the supervision of my local A&P...)
gsxrpilot Posted June 4, 2017 Report Posted June 4, 2017 Aircraft Spruce will have everything you need. You can often buy an entire screw kit to replace all of them. 1
Yetti Posted June 4, 2017 Report Posted June 4, 2017 Stainless screw kit for a Mooney is the place to start. You might want to buy some plastic washers to go under them. No A&P required. Inspection port R&R is covered under preventive maintenance section. As is adding brake fluid which is under one of the radio inspection panels. Might as well get a gallon of 5606 brake fluid 1

Jerry Pressley Posted June 4, 2017 Report Posted June 4, 2017 original had camloc fasteners. similar to dzus. would be a shame to replace them with screws. 2753-2 camlock I think. 2
carusoam Posted June 4, 2017 Report Posted June 4, 2017 (edited) Chris, you may want to confirm which fastener locations... There were screws for the access panels for the backside of the radios... There were camlocks for the cowl top. These camlocks were not stainless originally and had a tendency to get routed out rust layer after rust layer. old fuzzy memories of a 65C... Best regards, -a- Edited June 4, 2017 by carusoam 1
Jerry Pressley Posted June 4, 2017 Report Posted June 4, 2017 sorry misread which screws if they are on the panels for access to back of instrument panel just go into any fbo and they will probably give you what you need, a full screw kit is wayyyy too many screws
MB65E Posted June 4, 2017 Report Posted June 4, 2017 Kim D on the field has a lot of hardware. Poke your head in the parts room and ask for Kim or Shane. Show them what you have and have, grab a good handful and leave $10 cash. Good people. -Matt 1

Some of the radio access panel screw heads are stripped / stripping. Also, those rusty camlocks. I edited my post earlier but it doesn't seem to have stuck. I found them on Aircraft Spruce: http://www.aircraftspruce.com/catalog/appages/sb-mooney-cwl-kit.php (Hopefully that's not $300 per cam lock...?!) 1
jamesm Posted June 4, 2017 Report Posted June 4, 2017 On my 67'C radio access cowl (near the firewall) had a mixture of fasteners such as tinnerman nuts, speed nuts, and nut plates, sheet metal and machined screws some varied in size over the years. which I never understood why Mooney did that. I have since changed them all to #8 nut plates . and no longer having worry about people who are trying to help you by taking a sheet metal screw putting it into a nut plate or take a machined thread #8 screw into a speed nut fastener. In the case on my '67C three (per side) lower had speed nuts for #8 sheet metal screws with same spacing as standard nut plate. so that was no brainier drill them out replaced them #8 nut plates. The top section between firewall and base of the center line of the front windshield, where are 6 sheet metal screws that was little more difficult. So I decided to remove the channel piece that goes between the Firewall and base of windshield . I took it home put in #8 nut plates reinstalled channel piece. The cowl seals better and just better all way around. If you are talking the radio access panel near the tail section on the left side. I guess I try an aircraft salvage yard or Ebay then have auto body place match your paint scheme and paint for you. http://www.ebay.com/itm/1-MOONEY-AIRCRAFT-ACCESS-PANEL-FOR-RADIO-BATTERY-AREA/192189038451 Hope this helps, James
SantosDumont Posted June 6, 2017 Report Posted June 6, 2017 I think what you're looking for are the Camlock studs. I had to replace a couple of them. On my aftermarket cowl it's the 2700-4s so you might have to try a couple to see what size yours are. https://www.aircraftspruce.com/catalog/hapages/camloc2700.php https://www.aircraftspruce.com/catalog/hapages/sb-ss-protruding.php
