Before I break anything, I would like to get some advice.  I need to disassemble the Nippon Denso revcounter clock. What needs to be done? I have removed the clock from the mounting plate but it seems to be very solid and I have no idea how to proceed.
 
Best leave it to an expert then.
It requires the chrome ring to be broken to get inside it, then a special crimping tool (and new chrome ring) to reseal it.
I send mine to specialists for refurbishment.

I found a better way to open the ND gauges: http://youtu.be/hnF8_bSTqlU

If you want to close the gauges, you can find this here: http://youtu.be/oJxG6Y70qwE

If you have damaged the crimp ring and you want to replace the face plates with a new one, you can find these here:

If you plan to buy new rings, you can use pliers to cut the old rings off.
 
That was easy, just needed to replace the red GEN bulb lens with a clear one in order to get Sparkbright battery/voltage monitor led show the changing colors correctly.
 
My rev counter ( 1980 Jota 180 ) jammed a little while back and snapped the cable just below the head. I just wondered before I take it apart and break it if there is any sage advice to help me avert disaster. ( I once tried to fix an iPhone screen and lets say I won't be getting too many calls on that phone ; /

In 99% of all cases, the damper is empty and needs refiliment. That's only possible by disassembling the gauges.
If it is a ND gauge, it's a great opportunity to replace the face plates, paint the needle etc.
 
Thank you soooo much Stefan. Yes I'll take a peek at those gears. Fortunately for me I have fitted clamping rings which facilitate easy opening and closing of the instruments. I think I'll wait until the weather turns and then do it as it isn't stopping me riding the bike.

I do appreciate your advice on the mechanism which could be causing the jam.

cheers

The original faces are green/blue. If the face looks more blue than green, the faces has been discolored.

    Does the spelling of "discolored" mean you are Stateside ?? If so where in the USA ? It might make a difference for affordability !
