sloppy box

[handsomejackuk]

just going around my bike tonite and noticed a lot of slop in my gearbox, decided to check it further and noticed that the bolt that holds the gear linkage on to the gearbox was loose not loose to come of but just required nipping up job sorted........


thought i would shasre this with you.........

worth checking out as its not all that noticable but makes a diffference

A good point too.

That gearlever is subject to a lot of forces - jabs from boots, vibrations from that big piston leaping around inches from it's poor little shaft, not to mention the savage shearing forces on the tiny teeth that engage with those on the gearshift shaft..... It needs to be nipped up tight to cope with all those forces and to avoid excessive wear.

If the clamping bolt works loose, the splines inside the lever will be subjected to accelerated wear because they are unevenly transmitting all the forces necessary for cog-swapping so, if a clamp bolt's come loose like this, it's often worth checking the teeth on the pedal/lever for signs of advanced wear. I was once stranded miles from home after an enthusiastic gearchange stripped a worn out pedal of its splines on an ancient Triumph Tiger Cub.

I eventually got home by buying a pair of mole grips (remember them?) from a tiny village garage and clamping them onto the gearbox shaft. That gave me a pedal of sorts - but that's a story for the pub.

NB: The teeth on the gearbox shaft are case hardened, the ones on the lever usually aren't, so nearly all the wear will be in the softer lever.

think my geabox is still not quite right, i have acidentally jumped a gear a couple of times. I can change real quick without clutching. only need the clutch for first gear. does anyone else upchange real quick without clutching ?
