Difficulty changing up gear
« on: 10 March 2014, 10:21:30 am »
This has been getting worse for some time and it's now getting to the point of making riding tricky...

Any common fazer issue cause this? I'm guessing worn selector forks.

Also - any recommendation on where to buy replacements (excluding ebay).

I am down to my last set of selector forks in stock and they are being held for a customer, not many breakers will sell the selector mechanism without the complete gear cluster and even fewer breakers seem to want to split engines any more. if not ebay then maybe something like partsearch? failing that its dealer parts and hefty price tickets!

Ok - will do a bit of searching. No mad rush to do it, but it will need doing before next winter.


Just read your how to do the selectors post... you mention a bike bench, i guess you mean something you can lay the bike on it's side on?


How long would you say it would take a mechanic who hadn't done it before?

I believe the sort of bike bench that Deefer would be referring to is something like this

It might be worth changing the detent and return springs before delving into the more inaccessible regions of the gearbox.
Also, what is the state of the gearlever itself? As the sleeve wears against the pivot it gradually gives the lever more free play which makes changing gear less precise... the lever not adjusted to the optimum position for you also makes a huge difference.

Ok - I've already done the lever and linkage the original was very worn - the new one feels really tight and hardly moves compared with before.


I'll have a look at the springs since they are relatively easy to get at.

Out of interest have you already tried fitting the old one back on to see if it makes a difference?

No - the old one was viably shot - the rubber seal were broken, the joints were rusted and so loose you could pop them apart by hand.

Ah


Jus seems coincidental that this has been changed & you are having issues thats all


Would be nice if it was so simple, probably not though eh.


Good luck

Is the lever jamming in the up position and not letting the shift mechanism return to normal and ready for the next the upshift. Try changing up, then nudging the lever down a bit and try change up again.

it's not jamming in the up position - it always returns the mid position. It seems like it simply jams and won't change up. If I try a second (occasionally third) time, it will shift. A good way to describe it would be similar to the feeling of changing gear when the engine is not running.
