flyingchump Posted June 13, 2021 Report Share Posted June 13, 2021 Gents. I've been chasing down a slight vibration and my attention is currently on the nose gear doors. I'm installing new heim joints for the retract links but the length of the doors caught my eye. The aft portion of both doors extend over the belly 2-3 inches but the front of the gear doors don's sit on anything... Their just in the wheel well hanging from the retract links. Shouldn't the front of the doors overlap on the lower cowl? And yes, I know my one door is bent and not aligned properly. These photos were in the middle of the repairs. I also know that these doors are getting to the end of life... I'm hoping to squeeze a few more years out of them. Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted June 13, 2021 Report Share Posted June 13, 2021 You can see by the witness marks where they used to go. Also the four new rivets are probably supposed to be flush rivets. New doors are very expensive, I would see if you can find a used set or just patch those. See if other MS'rs can send pictures of theirs for comparison.

carusoam Posted June 14, 2021 Report Share Posted June 14, 2021 When it comes to used parts amd how they are supposed to align… and where they are supposed to be positioned…. @Alan Fox is often a great resource for pre-flown parts… He might have some good pics of Fat Albert around here… Best regards, -a- Quote Link to comment Share on other sites More sharing options...
Alan Fox Posted June 14, 2021 Report Share Posted June 14, 2021 The gear doors are trimmed back about an inch and a half up front , Those "Rivets" are screws , and are "supposed " to be countersunk , I have used doors , but they are 2 grand a set... I have new doors , at 2500 a set The new doors , are overlapping doors 1 Quote Link to comment Share on other sites More sharing options...
Yetti Posted June 15, 2021 Report Share Posted June 15, 2021 It's to let all the oil out of the leaky Lycomings which provide anti corrosion coating to the belly. Quote Link to comment Share on other sites More sharing options...

Since I rebuilt my engine, which appears to be leak free, I’ll have to pay more attention to nose gear lubrications. 1 Quote Link to comment Share on other sites More sharing options...

What's the benefit with the overlapping doors competed to the old style? 10 knots faster? reduce fuel burn by half? gain 2 inches?.. (manifold pressure you pervs) 1 Quote Link to comment Share on other sites More sharing options...

You only have to lubricate once ! Because then the engine leaks again and it does the job by itself. 1 Quote Link to comment Share on other sites More sharing options...

(manifold pressure you pervs) Overlapping doors are easier to fit, if they overlap 1” and your doors are mounted a half inch further apart than spec, they still overlap a 1/2”, flush doors would have a 1/2” gap They should also be easier to get a tight fit, and it appears they would be easier to manufacture as they may only require pressing whereas it appears just from the picture that the flush doors have a roll formed edge.

Pstone Posted June 16, 2021 Report Share Posted June 16, 2021 If old doors are $2,000.00 and new doors are $2,500.00 I would like to buy the new doors in exchange for my old doors + $500.00 Pat Quote Link to comment Share on other sites More sharing options...
