MT-7-235 Nosewheel Shimmy
Hey Folks. I've had my MT-7-235 for 3 and a half years (and yes I already know real pilots fly tailwheels, etc. etc.). But I have a serious issue with NOSEWHEEL SHIMMY on landing and takeoff. On landing I put it down usually in the vicinity of 55-60K, good speed, no bounce and around 40K, the nose wheel starts a shimmy dance. Usually keeps the shimmy going until around 10K just before clearing the runway. Right now I have a new Shimmy Dampner seal kit coming from Maule Parts. Hopefully that will help. Next step is a new shimmy damper itself for around $1700. Any suggestions or has anyone dealt with this before. Thanks for any comments in advance. See you in Llano, TX for the 2016 LoneStar Maule Roundup.

Had the same problem in my MXT Swapped out the steering yoke and through bolt. Cost less than $200 if memory serves me. Took care of the wheel shimmy, the yoke bolt holes can get elongated and the through bolt bends slightly causing shimmy. Also, helps to keep the font end light as possible, yoke in the lap eliminates shimmy at taxi speed.

Have had the same problem in the past on a customer’s bird, checked and re-bushed and new bolts in the torqued links, still had a shimmy, shimmy dampener checked-ok, replaced the nose tire with a Good Year Flight custom III tire- it has stiff side walls and a square profile not round like most tires, shimmy gone. The tire is pricy but worth it.
Works on Cessna's trikes also.

Thanks Tim. I will also look into that fix. Does that type of square profile tires have any wear characteristics that I would have to be aware of. Longevity wise, is it worth the money in your opinion. If it takes care of the shimmy it's worth it either way in my opinion.

Nose wheel shimmy
Long lasting tire with very little wear problems as long as you keep the tire aired up correctly.
I started using the Good Year Flight Custom II tire in the mid 80’s, now the Flight Custom III and have had very pleased customer’s with the tire installation.
