5854Q Posted March 7, 2011 Report Posted March 7, 2011 Hello All, Just replaced the biscuits on my 1965 M20C. All went well. While I had it off the tarmac, I noticed the nose gear has about 2-3 degrees (in both directions) of play; that is movement until the rudder linkage provided some resistance. Anyone know if this is normal? Thanks!
LT4BIRD Posted March 7, 2011 Report Posted March 7, 2011 Does the nose shimmy on a roll? If it does its too loose. If not your most likely ok.
JaredDavis Posted March 9, 2011 Report Posted March 9, 2011 I wonder what happened to this plane? http://www.ntsb.gov/NTSB/brief.asp?ev_id=20110223X03211&key=1 On February 23, 2011, about 0900 mountain standard time, a Mooney M20F, N891X, departed the runway after the nose landing gear collapsed during the landing roll out at Nephi Municipal Airport (U14), Nephi, Utah.
Jeev Posted March 10, 2011 Report Posted March 10, 2011 Not normal. I just replaced my linkage in my J with a kit from LASAR, they could rebuild mine by replacing the joints, bushings and linkages but I opted for their new design with an STC from LASAR and a 337 from my mechanic. Now my steering feels nice and tight with little to no slop. The kit was $995 and the install took about 6-7 shop hours.
5854Q Posted March 11, 2011 Author Report Posted March 11, 2011 Thanks to all for thoughts & suggestions. Even though there is no shimmy on rollout (landing nor takeoff), I'll be disassembling the gear & inspecting linkage joints for any wear.
rob Posted March 11, 2011 Report Posted March 11, 2011 You're doing the right thing. If you have that much play, I would definitely rebuild it. Don't wait for shimmy.
Shadrach Posted March 20, 2011 Report Posted March 20, 2011 Shimmy in Mooneys is almost never caused by loseness in the gear. It is caused by misadjusted gear. As in nose gear retraction rod eccentrics misadjusted. Most of the left right play is in the steering horn. If you have a shimmy often times it's a sign that the eccentrics that set fore and aft gear position need to be adjusted. 1
1970m20e Posted March 21, 2011 Report Posted March 21, 2011 I've got a question about the nose wheel shock absorber. As you can see in my picture my old shock has been removed. Going through pictures of Mooney's I see most of them also have no shock absorber. Is there a reason why it was installed and then later it is removed? I can imagine that it's to prevent the nose from bouncing too much on landing. Mine was removed because it no longer had any shock absorber action and we put new Lord shock discs in. So my question is, why has everyone else's Mooney had theirs removed? Because it was no longer working or was it that it isn't really necessary.
carusoam Posted March 21, 2011 Report Posted March 21, 2011 70E, Checking a recent post on this topic.... http://www.mooneyspace.com/index.cfm?mainaction=posts&forumid=4&threadid=2334 "The shock absorber was found to be in effective and was removed. Email me direct and I will send you the approval drawing to remove the shock absorber. sellis@mooney.com" The words come from Stacey Ellis at the factory. Check with him for proper removal procedure. Best regards, -a-
N400YS Posted June 26, 2013 Report Posted June 26, 2013 Hi All I'm a new Mooney 1966 M20E owner. Very glad to enter in the community even if the plane I bought needs an extensive restauration.... My plane have all the mooney problems due to poor maintenance except corrosion and a good engine...not so bad . I'm fixing the soggy tanks, Pannel and avionics have been checked, brakes are checked and so on. I noticed a very bad play on the steering that give a very bad feeling at the landing (8 seconds ride...what a prank ) So I will replace the steering horn with a LASar REBUILT one. Does someone who already made it, give me some advises to proceed ? What is the easiest way to replace that part? Gear up? Gear down? Thanks Olivier France
