kingsley Posted May 8, 2007 Report Posted May 8, 2007 Hello New to this forum Im having an issue with my gear box. The first sign was a broken bolt on the shfiter that locates the centering spring and acts as a limiting bolt to limit the travel of the shifter. I replaced the bolt with genuien yamaha replacment. That fixed the problem and the box worked very well for a few hours of riding. Until i could only select 2nd and 3rd. After pulling the side cover off again, i found no signs of breakage like before and was able to regain all gears with the use of the shifter while in the shed. I may of had the selector jump out of alingment. But The part im concerned about is the slop that i have only in first gear. With the side cover off, i can rotate the input shaft back and forth 1/4 of a turn before the slop is taken up but have minimal/aceptable back lash in the rest of the gears. Is this normal for 1st gear, it feels like way too much for my liking. Im getting the feeling that a tooth may have come off of the 1st gear and may have lodged it self in the seletor barrel, limiting the rotation of the barrel and being unable to select other gears. I also noticed a slight metalic flake present in the oil but looked to be aluminum. Many thanks for any help Kingsley Quote
