smiths speedo
« on: 20.07. 2014 18:00 »
Hi all,
My Smiths speedo (ssn 5001/00b) fills with water when it rains (got caught at a bike rally in a hurricane this weekend). Managed to dry it out with a air bed pump but its dirty/water stained inside. I've had a look and it seems the gauge is assembled then the front flass and chrome surround crimped onto the external case. is this right? Which means theres no way to dissemble and reassemble. Any help appreciated. Pics attached.
If you don't start, I'm going to give you a damn good thrashing!!!

G'day Daz. The bezel should be screwed onto the body over the glass. They can be a real bugga to get off without damage to the unit or self. I tried to remove mine a few weeks back and gave up  *pull hair out*.

Ah Musky go to specsavers  *roll*

Daz,
your speedo is a later magnetic type and not original on an A10
The bezels are indeed crimped on and difficult to remove and replace sucessfully
New bezels and seals can be bought from "classic bezels"  http://classicbezels.com/
I have machined off an old bezel and made a jig to fit a new one, a lathe is required tho

Maybe you could seal around the glass with silicone?

not a lot is original on my bike John. Thanks for that info. Will try and seal it and put up with the dirt in it already.
Code should have been SSM 5001, which makes sense. Speedo/Smiths/Motorcycle?
Been trying to find out what the codes mean. Still looking.
Tacho is RSM 3001 - Which I guess is Revs/Smiths/Motorcycle.
cheers.

Am I right that the mount you have prevents you using a pilot bulb. the open bulb hile under the mount allows water in.  The far east copies are more reliable and cheaper than getting your one fixed.

No Warmshed. I have removed the bulb to get air in to finish drying it off. Not sure where the water is getting in. Will use this original one until it expires. Not the right setup for the bike anyway. The dials are off a much later model.
cheers.
