Inspect tyre for out of round, slight bulges or flat spots.
Check torque on nose fork, engine mount to frame.
Check security of steering attach and dampener attach points.
Maybe the dampener is worn out or seals are gone.
Check steering horn bolt is not fouling the air intake tube (common).

I had a similar shimmy on my 97 mxt-7. Check out service letter#62 on the maule air website

http://www.mauleairinc.com/service_lett ... ter_62.PDF

I found the steering yoke bolt holes were elongated and the steering yoke bolt was bent on mine. It wasn't very obvious upon visual inspection and just a very slight sloppiness was detectable when inspected by feel. A very apparent wear was noticeable and the bolt was found to be bent when we removed it. I replaced the bolt and yoke as per the service letter and shimmy was gone.

I have the MXT-7-180A from 1997 and my shimmy seems to be empty, not working, not damping, do nothing any more. It doesn't shimmy due to my smooth landings 8) - but I'd like to repair it.

The installed has this number on it, missing a portion of it unfortunately.

Does anyone know where to get a Servicing kit and manual for this one? Can it be serviced?
Alternatively - is there any good replacement? Maybe for one of these maintenance free shimmy dampers that are built into Cessnas etc. nowadays?

Maule sells the "O""ring kit give'em a call 229-985-2045

Refill with 5606 hydraulic fluid , not completely full or you can't get the end cap back in as the rod does not pass all the way through like a Cessna , you have to allow for the volume of the rod and seating depth of the end cap . If you're careful you might be able to "burp" the assembly with a.005-.008+/- feeler gage blade between the end cap "O"ring and the tube. Just use the feeler gage sorta like a shoe horn and be sure it well worn ( meaning smooth rounded edges so as not to be able to cut the "O"ring)
