993 - Odometer stopped

[Ocho]

Hello all

Some may be pleased if this happened to stop the miles racking up, but I'm well over that!

The odometer and trip-meter have both stopped suddenly. Speedometer still operating as normal.

Anyone else had this before or have any suggestions. I've never had the dash off before - sounds a bit scary if that's what's required, so (if this is needed) any tips with that too please?

Thanks

I only know the 924, but assume the 993 will be similar.

In the 924 there is a little plastic gear which drives the odo. Over time it becomes brittle and eventually falls apart.

Replacements are readily available and cheap. Replacement is a strip the unit and press the new gear on. Pretty straight forward.

Hi - did you reset the trip meter whilst driving, this is a well known way to break one of the cogs that drive the milometer

I had the same issue, and the speedo was sent to http://www.reapautomotivedesign.com/ (I think, my local Porsche guy managed it)

I don't remember exactly how expensive it was, but recall it was reasonably priced, and no dash removal was required

Had the same issue with my 993 whilst on my way to 911 Virgin. Quite a common issue they said and suggested I go to Reap as well who very kindly repaired it while I waited. Can’t recall the exact cost but wasn’t that expensive.

Thanks all.

@CoolC - your definition and mine of "pretty straightforward" may differ a little, but I've found a YouTube video on the strip-down so may possibly give this a go one weekend...

Found the parts on Design911.

To do it yourself you have to pry the bezel off with a screwdriver or similar, unbending the bezel's crimped over retaining flange and working your way around the bezel circumference. From the videos I watched the bezel ended up looking a mess, a bit like someone has opened a tin of beans with an old style tin opener. Instead I sent my 993 Speedo off to Ryan Linley Restoration. He has a machine that carefully folds the flange without damaging it to undo and remake the crimp. As a result my repaired speedo looks entirely original, having been cleaned inside and the failed odometer gear replaced. In addition to the failed odometer gear Ryan found a small moulding defect in one of the increment gears between the counter wheels. That defect was causing a tight spot as the wheel was turned so the part was changed too. It was a couple of years ago and cost me £ 160 + return postage. Ryan was also a lovely chap to deal with.
