Title: Odometer trip knob broken
Post by: 1.21GW on June 14, 2015, 11:04:15 AM
Title says it all.  The knob that resets my trip meter stopped working when I tried to reset it at fill up today.  It stopped working as I twisted and then as I wiggled it to get it to catch on something, it pulled out.  I tried to put it back in but it won't lock or latch onto anything inside the hole.

I would normally say, "meh, who cares?" but I use the trip meter to keep track of gas tank levels.

So, suggestions for repairing or replacing?  I'd prefer to fix cheap it but would be open to replace if not too too expensive (is there a stylish sleek odometer?).

The knob itself is replaceable and IIRC is threaded and is only intended to be turned in one direction, but it's been so long since I had a stock gauge I kinda forget.

Thanks, DP.  Looking at the part in the link you posted and comparing to mine, it seems that something internal broke off and is (thoroughly) attached to the knob:

Wrong answer!

Okay, any cool speedos out there?  Something simple.  No tacho needed.

Good idea, Howie.  I will look into.

I wonder how it tracks distance?  GPS I guess?  I don't like the fact that it is battery operated (rather than solar or hooked up to the bike), but I'd hope battery life is long.

That was just one model.  Look up CatEye and Sigma cycle computers.  Transplanting the speedometer from Nibor's gtauges into yours would work too.

Most use a magnet attached to a spoke, which passes a sensor fixed to the fork. To calibrate, you measure the distance traveled for one revolution of the wheel and input that into the computer. It computes speed and distance based on the revolutions.

Some can be pretty finicky as far as minimal distances between magnet and sensor. The wireless ones require a battery in the sensor and one in the computer, but they tend to last a while.

I ordered one of these for an ATV, haven't got it yet, so no FHE.  The one that's coming is the Vapor model but they have simpler and cheaper ones.

I've used Trailtech speedos before. Be aware that their warning lights have been noted as being very dim in daylight. They did do a change a few years ago and went from incandescent to LED, but the LEDs they went with were marginally better. I ended up having to install brighter LEDs to replace those.

On the plus side, their speedometer, as verified by GPS, is very accurate.

One other item of note, is that their documentation does not provide instructions for transferring the bike's existing mileage to the display. That may or may not be a problem for an ATV? If it is, PM me and I might be able to help.

Changing an odometer reading is a violation of federal law...even if you're doing it to reflect the actual mileage of a vehicle. Probably why there's no documentation. ;)

Yep. Exactly what I was told when I called them about it.

On an individual state level, some states have a documentation process which legitimizes/documents it. It usually means a new title being issued with words to the effect that the odo was replaced.

HD sells replacement speedo/tach units - if you want a tach for some reason...  and they somehow have a procedure for them to learn the mileage from the old speedometer fwiw.

I like solution, if only it didn't involve besmirching my duc with HD parts.

Thanks, I sent you a PM.  I was wanting to transfer the mileage but assumed there wasn't a way to do it.  ATV's don't fall under the Dept of Motor Vehicles jurisdiction, at least here in NV, so there shouldn't be any legal issue.

Careful Bob...it's a federal thing on odometer tampering.

Nate, for the record I looked up the federal law.  Per part (a) below I will be adjusting the mileage on the new odometer so that it remains the same as before the replacement.  All completely legal and also in compliance with common sense.

49 U.S. Code § 32704 - Service, repair, and replacement

(a) Adjusting Mileage.â€" A person may service, repair, or replace an odometer of a motor vehicle if the mileage registered by the odometer remains the same as before the service, repair, or replacement. If the mileage cannot remain the sameâ€"
(1) the person shall adjust the odometer to read zero; and
(2) the owner of the vehicle or agent of the owner shall attach a written notice to the left door frame of the vehicle specifying the mileage before the service, repair, or replacement and the date of the service, repair, or replacement.
(b) Removing or Altering Notice.â€" A person may not, with intent to defraud, remove or alter a notice attached to a motor vehicle as required by this section.

Ordered a Cateye brand bicycle odometer as my temporary fix, per Howie & D3via@nt suggestions.  We'll see how it goes.

That didn't work.  Bicycle design does not lend well, in particular the fact that the magnet is made to go around a spoke.  I don't have spoke wheels.

Will order a used ebay speedo sometime.  Can I just swap on into my console or is it a major project?

Couldn't you use a different magnet?
Title: Re: Odometer trip knob broken
Post by: Langanobob on July 12, 2015, 05:12:00 PM
Yes, any magnet should work, but a rare earth type is better.  My "one size fits all" Trial Tech Vapor speedometer came with a couple of magnet configurations.  One magnet was just that, a magnet with no mounting bracket that you could epoxy wherever you found a good place for it. Mine ended up being about 3/8" away from the sensor and it works fine.

The magnet for my house alarm fell off the door.  I replaced it with a magnet from a hard drive.  Works fine. Duct tape will hold it on your wheel until you figure out something that is better.

Pretty much this Bob. My Spa tach/speedo came with a small neodymium magnet that's Devcon waterproof epoxied to a brake rotor bolt. Sensor is on the swing arm...been that way a long time. [thumbsup]

What do they use to adhere the weights for balancing wheels to the rim?

Two sided tape...like for carpets or auto moldings...

but it isn't forever.

You should be able to find a speedo (with the knob) on EBay.

I have.  But I was looking for the quick fix.  I also wasn't sure that the issue with laws regarding odometer replacement.

Speeddog: do you know if I can just swap a speedo into my (stock) cluster?  Or do I need to buy the whole cluster?  This is what I was looking at:

I don't know the legal ramifications of speedo swaps in your location.

AFAIK, as long as you divulge the actual mileage upon sale of the bike, you're good.
I suspect there's folks in your area that know the details.

You should be able to swap that speedo into your cluster.
Ask the seller for pics of the back side of that unit, I've run into differences.
Compare the pics to the back of your unit.

Don't throw that knob away, someone may want it.
