Zee shifter

[seanryan]

In ballyhoura the other day the downshift paddle stopped returning, resulting in me having to push it back, i assume its a spring popped off or broken or something.
My question is, how easy is it to access the spring in question and can it be replaced?
Or is it worth the hassle?

Almost guaranteed the hook at the end of the spring has popped off. I've had to do repairs on about 3 Shimano shifters in the last 20 years, so it's a rare event. I'm not sure how easy it is to get into the Zee shifters, but if it's like the other ones the lower housing can be worked off around the thumb lever (It often comes off really easily with the lever in one particular position). Mind all the small screws carefully. There are sometimes a mix of long and short and it's best to get this right when reassembling.

As for spares, look up the shifter on Shimano tech docs and see if it's listed as having available - http://si.shimano.com/php/download.php? ... 0-3439.pdf - nothing internal at all ...

Currently in pieces on the coffee table in front of me, think you might be right, just very awkward and fiddly!
