Over inflation can push the tire out-of-round. Try 17 psi. As the others said, loose scissors bolts can cause shimmy. They should be tight enough to stop side play in the scissors but must still allow the scissors to function. Weight down the tail with sandbags on the horizontal stabilizer and see if the nose wheel still drops as it should. Another thing to check is the amount of play in the nose gear strut assembly. While the tail is weighted down try to push the nose strut (p.n. 415-34085) front to back and side to side and see if it has any play inside the nose gear cylinder (p.n. 415-34085). If so, the internal bushings are worn, which will cause shimmy.

It's a 1946 415C, serial number 510.My question is this; Can someone tell me the correct tire inflations? I have found conflicting information in several Ercoupe manuals. The nose wheel is 5.00 x 5, and the mains are 6.00 x 6.I have a fairly severe shimmy at landing speeds, which stops at about 40 mph or so. There seems to be no shimmy on takeoff. I'm thinking that incorrect nose wheel inflation could be the culprit.Bernie Wiklund============================================================================== To leave this forum go to: http://ercoupers.com/lists.htm
