Just bumping this to the top.

Anyone have a photo of the position of the cowl flaps arm when it’s rigged properly? Mine wont stay closed in flight Due to the air pressure inside the cowl and I believe it’s because the arm ends up in the wrong position when closed. This is mine in the closed position from the right side.

Some of mine are threaded, but the one that is in the picture is press-in. I know OZW well. I started my Private training there and used to live about three miles inland. Moved to Brighton six years ago and got deeply involved with 45G. I can come down for pizza at the Airport Inn, or you can come to breakfast at 45G. We serve at 9:00am sharp in the clubhouse on the field. We normally start gathering between 8:00 and 8:30. The food is modest, but the hangar flying is the best you'll find. We'd love to see you.

Sent you a PM

I found this one missing on the right side during my last annual. Had to VERY CAREFULLY drill it out. By standard, they're the press-in style of zerk with the serrated, and smaller than anything I could find locally. McMaster Carr has them. I believe it was part number 1102K52. You'll also need a tool like the one at the link below. I had to grind a taper on the nose in order to get it to fit next to the flange and rivet. https://www.amazon.com/Lumax-LX-1430-Silver-Straight-Fitting/dp/B000MCZKB0/ref=sr_1_8?keywords=zerk+tool&qid=1555587614&s=automotive&sr=1-8

Thank you very much. I timed the flaps on the ground last night. Depending on the speed in which the valve is opened, it was between 7 and 3.5 seconds, but certainly more consistently toward the faster time. Spoke with my mechanic and we're going to make an adjustment this weekend.

That's the parts manual. Different book.

Either this is a different version of the manual that I have, or mine is incomplete, because this graphic isn't present. Anyone have a PDF copy of this manual?

Yep. It sure does. I looked at the maintenance manual, but the revision I have is about the PC system on page 6-14 and there is no page 6-15. What I have is Rev. H 11/1/85.

Thanks! I'll take a look at the manual. I'll time them tonight, but it seems to me that it's more like 5 seconds...maybe less.

Since the POH doesn't mention a single word about go-around procedure in my '67 M20F, I'd like to know what you all do. The main issue I have is that once the hydraulic switch is raised the wind pressure removes all of the flaps almost immediately. Of course, we were all taught to raise the flaps incrementally, which I am finding to be impossible in this plane, no matter how fast I try to work the lever. Are there any tricks, or secrets of which I am not aware?

I can't find an SB7 related to tanks. SBM20-230A is the only SB I can find related to tanks and seals. I do have the service manual.

Looks like maybe PR-1428-B2?

1967 - M20F Is the PR-1403-G-B2 sealant called for in the service manual still valid for the access panels? I know I read somewhere about some of these part numbers changing. Thanks.

I love McMaster Carr. One day shipping to my front door and they have every oddball thing I've ever needed.

I always fly with my button out. lol

This is helpful. I'll start searching. The "washer/vacuum" line sold at the auto parts store is stiffer and has a thicker wall than the original tubing, which has a neoprene feel to it. Several of the selections from the auto parts stores were marked that it was good to 1 bar. Seems to me that's as strong as it's going to get without stepping up to hose that is reinforced with fiber braiding.

Yesterday, I went to every auto parts store in town. None carry 3/16 tubing. It’s all either 5/32 or 7/32. The 7/32 seemed to fit snug enough. Ground test in the next day or two. The weather is supposed to be garbage today.

Yeah. I wasn’t sure if they all came that way, or if it was an option. My clock was moved to the panel years ago.

I found one, but I'm definitely going to save your link and number. Thanks!

Airspeed. This is an illusion. All is well with that connection.

Thanks for all of the feedback, guys. I'm going to go ahead and replace all of the vacuum tubing and filters under the panel and then run the checks per the manual. I'll let everyone know how it went. For reference, the step is retracting fully.

My plane is pulling pretty hard to the right when my yoke valve is installed. Been doing this over the entire year that I’ve owned the plane. I understand that this means that there is likely a leak on the right side of the system. However, we just had the plane apart for annual and found not find any breaks in the tubes, or connections. Also, all of the servos look really good, including the tape, and feel like they have a balanced amount of pull when manipulated manually. What does look bad is pretty much all of the surgical tubing that comes off the turn coordinator. Have any of you seen this tubing cause an imbalance in the system? Additionally, does anyone have a source for this tubing? I really don’t care about the functionality of teh autopilot, but I love the idea of being able to use the wing leveler.

Not as sophisticated as the rest of the comments, but my F needs to be leaned on the ground nearly to the point that an application of power will cause the engine to stumble. Took a while to figure this out, but now it’s second nature.

Grease grooves.
