I just did this repair.

Same idea, but I found that a square faced punch and very light tap
with hammer did same. Also, as per your comment, I also made a small
bracket (tab) to keep the shaft and gear in place should either "walk"
out again.

Some pics here of an '85 1.9 WBX speedometer I repaired:

One thing that i didn't get right on this speedometer was the main and
trip odometer coordination; when trip odo white wheel hits 0 the main
odo does not flip to next number. Simply zeroing the trip odometer
(once speedometer installed) doesn't seem to do it.

If one takes the numbers off the speedo, I'm not sure if one should
zero the trip odo first, but there is a slot on the upper RH gear (or
wheel? can't recall) that should somehow coordinate with the trip odo
via the small black gear.

I may take my older diesel speedo apart again and take some of  what I mean.

Neil.
