Gearleg shimmy

Post by painless »

Thought I would submit my experience to the data base for others to reference.

I developed main gearleg shimmy in my left gear (6a) after I swapped tires due to wear. These are the original tires that came with the kit, and did not have a reference spot to align the stem with. So as a result, when I remounted the left tire, it was not in proper balance. I borrowed a static tire balancer and sure enough, the left wheel/tire was WAY out of balance.

I balanced the wheel with the stick on weights you can get at an auto parts store, and then further secured them with high speed tape. Checked to make sure the bearings were well packed, and properly seated.

I cannot believe how much of a difference it has made. Rollouts are now smooth as a baby's bottom, where before I would get shimmy at around 40mph. If I ever see the need to remove the wheel again, I may deflate the tire, crack the seal and re-clock the tire to get it in better balance. For now, I will go with the weights in place.

Your mileage may vary, but I would suggest you check your wheels/tires for balance.
