|
|
Hi all (new here)
I've got an issue with my gear shifter on my CBF125.
Attached is a diagram from BPH - it's the bolt labelled 22.

I can't tighten this up too much or the pedal won't move - any looser and it unscrews itself over time. I bought a new bolt (22) and washer (16) to try and fix it, but ran into the same issue. I'm sure I'm meant to be able to screw it tight and still have the pedal move freely which makes me think there's a part missing. When I first got it - it looked like it had the remnants of a white soft rubber ring in there. Couldn't tell if it was a bodge or not and I can't tell from any diagrams what bit I need (if any)
For context, the bike has been through the wars and almost nothing has been maintained for 12000 miles - most of which it spent outside. I picked it up a few months ago for £200 and have spent a good bit of time getting it roadworthy - just passed it's MOT - this is the last pain point.
Cheers all. |

No` 2 lever is the gear shaft lever and is fixed.
I hope the washer is the correct one and does not slide on the stud as well. |
This. ^ The pin the lever pivots on should be marginally longer than the sleeved portion of the lever, it should stick out very slightly when the lever is fully in place. The bolt and washer then tighten down against the pin, not the lever.
If it's sticking out too much, you will get a lot of sideways play, if it's not sticking out enough, it will cause the lever to bind.
As jaffa90 says, the washer should fit over the threads but not the pin. If it fits over the pin too, that's at least part of your problem. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

If you're going to be filing aluminium alloy then a good tip is to french chalk your file first to stop it from clogging (you can get sticks of the stuff). It's horrible stuff to clean out otherwise. |
