[shinzon1]

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

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.
