Marauder Posted April 12, 2019 Report Share Posted April 12, 2019 Exercising my right under Part 43, I noticed during my oil change the quick drain on my engine looks like it might have begun seeping a little. Two questions: 1) For the IAs, am I allowed under Part 43 to replace the quick drain with another one? If I didn’t have a quick drain, I would be removing a plug. Is replacing the quick drain like installing the plug? 2) I have an IO-360 A1A, is this the correct replacement quick drain? https://www.mcfarlaneaviation.com/products/product/A5020/ And is it the same has the one on Aircraft Spruce? https://www.aircraftspruce.com/catalog/eppages/safOilDrainValves.php?clickkey=6418 (And if it is, how do they get away with an almost 100% mark up?)

orionflt Posted April 12, 2019 Report Share Posted April 12, 2019 Question 1, yes you can Question 2 it is Question 2B it's a certified aviation part best thing to do is to pull your current drain and just replace the oring Quote Link to comment Share on other sites More sharing options...
orionflt Posted April 12, 2019 Report Share Posted April 12, 2019 What is the o ring replacement number for the P5000? 2 each of AN6227B-6 and 1 each of AN6227B-7 are the replacement o-rings for the valve. Quote Link to comment Share on other sites More sharing options...
orionflt Posted April 12, 2019 Report Share Posted April 12, 2019 here is the o ring for the aeroquip valve: Valve O-Ring, All Models MS28775-011 Quote Link to comment Share on other sites More sharing options...

I don’t think it is leaking from the O ring. I have never seen this type of drain before. I can see an actual spring and it looks to be leaking internally and coming out the end of the drain, not around the base. I’m headed over to the airport soon and will snap a picture of the little bugger. Sent from my iPad using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...

Sent from my iPad using Tapatalk Pro there is an internal o ring, that is what is probably leaking those were the different numbers i gave you. the base gasket is a copper crush gasket.

Marauder Posted April 12, 2019 Author Report Share Posted April 12, 2019 Mine looks absolutely nothing like this. Maybe the internal mechanism is the same but it doesn’t look like it from the outside.Sent from my iPad using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...

orionflt Posted April 12, 2019 Report Share Posted April 12, 2019 thats one of the first drain valves approved, i believe it was aeroquip but not sure. either way the design is the same. Quote Link to comment Share on other sites More sharing options...
MB65E Posted April 12, 2019 Report Share Posted April 12, 2019 That’s the Curtis CCB-37000. Aircraft spruce when I ordered mine says it’s not PMA’d for oil use. However, I called the MFG directly and they gave me the data I needed to install it. I’m not sure if spruce has since updated their data. Use some heat and patients getting the old one off. -Matt 1 Quote Link to comment Share on other sites More sharing options...

Could not figure out what it was. Believe those are 3/4" pipe threads. I wondered if I could replace it. Then I wondered if it was not there, could I remove and replace a pipe plug to drain the oil. Heat gun and permetex. Stand by and I will get a spruce number 1 Quote Link to comment Share on other sites More sharing options...
Yetti Posted April 13, 2019 Report Share Posted April 13, 2019 P5000 1/2 NPT (National Pipe thread) gonna need a heat gun to get it loose. P5000 Lyc. (same as Aeroquip AE80664H) 1/2 NPT 07-00879 $92.5 1 Quote Link to comment Share on other sites More sharing options...
Marauder Posted April 13, 2019 Author Report Share Posted April 13, 2019 Thanks. Any advantage of going with one brand over another? The Aeroquip version that is cross referenced is a lot more expensive that the one you posted. Do you know if any have a better track record than another?Sent from my iPad using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...
Yetti Posted April 13, 2019 Report Share Posted April 13, 2019 It's a way smaller hole than what you have on there so it takes longer for the oil to drain. One day I will pull the original apart and replace the O rings so it is ready to go when the current one fails. It has one job. Not leak. It does that well. 1 Quote Link to comment Share on other sites More sharing options...

Yep, same ugly POS on the Mooney right down to the 90, the 172 has the same one less the 90 plus something similar to this, just held on with a zip tie Quote Link to comment Share on other sites More sharing options...
MB65E Posted April 13, 2019 Report Share Posted April 13, 2019 The 37000 will last longer and flow better than the P5000 will. I’ve worked with both. The 37000 is Stone Age in a good way. -Matt Quote Link to comment Share on other sites More sharing options...

It didn’t have the honor of the piece of safety wire hanging on the spring release either... Now we know how easy it is to dump all the oil out the drain... So many newer designs for that. Swapping it out will make you feel better.... Best regards, -a- 1 Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted April 14, 2019 Report Share Posted April 14, 2019 It looks like your lock wire may be biasing center of the valve. This could be affecting the o ring seating. You may want to take it off and see if it stops leaking. If you are going to replace it go with the Curtis. They are made here in Chandler AZ! 1 Quote Link to comment Share on other sites More sharing options...
