----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- Craig; The oleo portion of the Coupe/Alon/or in your case, M-10 works to cushion the initial landing shock. The rest of the time, during taxi and parking, the cushion effect is provide by the Belleville Springs. I have run into the problem of the Belleville Springs coming apart, which causes them to not function properly. They can hold the strut up or down depending on the
failure mode. The original Coupes had large rubber doughnuts which did the same job. First, regarding servicing information, call Lee Gauger at Skyport Services in Wisconsin. He has service manuals on all the models. What you need is the service manual for an Alon which will cover the Belleville Springs. His number is 800 624 5312 (I think if my memory didn't give up) or 262 534 4233 Ext 207. In order to service the hydraulic fluid level in the struts, the aircraft needs to be jacked so the main gear wheel is just off the ground. Then you remove the lower bolt on the oleo/spring strut, and swing it rearward and down until you can pull it out to a point where the "O"ring on the bottom of the inner tube is just above the servicing port. The servicing port is on the rear of the strut and has a spring loaded cap which keeps out the dirt. Once the strut is in this position, you fill the tube with hydraulic fluid. Then reverse the process to put it back together. However, it sounds like you need to pull the strut completely apart, which can be done in the same jacked position I described above. You just remove the outer tube completely off the inner one. The Belleville Springs are on the outer tube. When you have it completely off, you should have pressure generated by the Belleville Springs against the top and bottom fitting. If not, the springs are worn or possibly coming apart. You can remove the springs by collapsing the stack using large clamps, and pulling the stack together until the snap ring, near the top, can be seen in the holes of the upper, bell shaped, fitting. Just pry the snap ring out of its grove and carefully release the pressure on the clamps. Then everything comes off the top. This procedure is also explained in the maintenance manual for the Alon. Good Luck!
