Another alternative replacement speedo

Recommended Posts

I have been reading troutman's thread about the ETB speedos,  and after searching around for alternatives, I recently found this in the UK (although it will be Chinese) from a shop called Rally Designs

It's 80mm and 30mm deep after the bezel. I bought it because it looked kind of OK and wasn't massively expensive, it may be a tad optimisic...

It has bewildering instructions, but I think it will do the job (but for how long :rolleyes:) .

I have managed to get it working on a bench, and figured out how to set speed which involves riding at a steady 20 Kph and hitting the button!!!!

I've just noticed fingerprints (glue?) on the inner bezel, do you think someone manage to open it up and prolong it's life!?

Well I wouldn't be buying it for its aesthetics. Is it waterproof?

Hah. Yeah it's sealed and waterproof, the bezel is actually part of the body, quite solid for a Chinese thing. I guess I might want to think about the back of the original dash cover where the speedo cable used to go, the plug is at the top of this unit, but some kind of silicon sealant might not go amiss. 

 

P.S. The needle does a little "sweep" when powered on, how sweet.

As long as it shower proof is all thats needed and shielded from slipstream blown water. Fully sealed instruments always end up fogging up.

Interesting take on "waterproof." I've worried myself silly trying to seal the Speedhut clocks.

A couple years on and "so-far-so-good", but looking to ride into Hurricane Dorian for the Fifteenth South'n SpineRaid.  "We shall see what we shall see. Won't we?"

I've had several BMW's and Triumphs with fully sealed instruments and all they do is fog up and stain the inner face of the glass. When it first happened to the BMW instruments back in the 80's I consulted a well known and respected instrument repairer and maker here and he advised me that he had talked to VDO on a trip to Germany about the issue.

They were aware but said they just built the instrument housing to BMW specs. His advice and solution was to vent the back of the instrument via some shielded holes. Worked perfectly.

The Triumph (modern) instruments had vents in the rear case but the baffle fitted inside hindered the ability to cope with changes so the baffles were removed and problem solved.

If they are just sealed up there’s always some water vapor trapped inside. What you need is a vacuum or inert gas but as you can imagine that’s overkill. Except for this forum. :blink::D

I've even seen someone that rigged up a pump to evacuate the air inside the instrument with the inlet air going through a tube with an inline silica gel reservoir. Worked as long as you were prepared to replace the silica gel every week as silica gel is only meant to be used in sealed/confined places not having air drawn through it.

Talk about overkill.

Wasn’t that on a Breva or something over on WildGuzzi? I think it would have been less hassle to move to a less humid climate.

2 ways to fix foggy dials. 3 if you include filling with dry nitrogen!

1: heat the glass - this doesn't require the dial to be completely airtight.

2: seal the dial so it's 100% airtight with a good desicator inside.

Never tried either!

Just my experience with keeping CCTV cameras fog free.
