    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

tach whine

on my way to work this morning and pulled up to stop light and my tach was making a whining noise. is there a way to lubricate it? and if so how? couldn't find anything in my book.
 
I cut mine open and lubed them with synthetic bicycle chain lube. I've been riding with no instruments for a while now... ;) Time to add them on.
 
Accidentally posted the following reply to the old thread that was linked above.

Both my speedo and tach were making crazy loud noises and bouncing alot. I unscrewed the cables and sprayed some Liquid Wrench (blue-green can) up in where the cable goes, and it seemed to quiet them quite a lot, and significantly reduce the needle flutter. Not perfect, but much better.

I imagine that some more LW and time would further improve things as it gets worked in the mechanism.

I had similar success with WD-40 in a '92 Volkswagen Speedometer that was noisy in cold weather, and PB Blaster in another '92 Volkswagen's speedo. Although, the PB Blaster made the needle read super high for several days but then it settled into normal operation. Not sure why that happened, but it did.
 
Don't cut anything open, it's not necessary. Take the gauge off and turn it upside down. Shoot some spray grease in between the part that spins with the cable, and the part that the outer cable threads onto.
 
Gauge lube

Gauge lube

I use a teflon based lube on my gauges and cables, TriFlow is a high pressure high rpm lube and is more stable and penetrates dry bushings rather well.

+1. That's the way.

And, if you take 'em out and invert 'em like that, you can use a 'square-drive' bit you find in universal bit driver kits in a drill to spin it and spray lube at the same time.

Works for me every time.
