Gauge maintenance?

[mcsinfl]

The Autometer Phantom gauges in my truck are 5 years old. Both the pyro and trans temp are performing flawlessly. Lately my boost gauge has had a slight pause around 10-15 psi as the boost pressure drops when I let off the throttle, otherwise it's been functioning fine. It got me to wondering if I should pull all of them out and perform some maintenance.



Is there anything I should be doing such as cleaning/blowing out with compressed air or lubricating? Any advice is welcome.

anyone have any ideas?

I have autometer phantom gauges in my truck (oil temp, trans temp, electric fuel press). My boost and pyros are Isspro. Never any gauge problems yet. (knock wood).



I don't know of any gauge maintenance- they just sort of do their thing.



One thought- when you see a pause or apparent "hitch" when boost drops, it may be premature to conclude that the gauge is the issue. Maybe the gauge is telling you exactly what's happening. Maybe the boost regulator (waste gate, whatever) is getting crusty, or the vacuum servo is developing a hitch. Maybe time for an "Italian tuneup"

If you decide to try any maintenance on the gauge, I would recommend taking it apart and adding a tiny bit of clock oil to the mechanism. You can find convenient syringes of clock oil at your favorite local clock repair shop.

You want a TINY bit of the stuff. One little drop from the end of the syringe is generally plenty on a moving mechanism.

could be... i'm trying to eliminate gauge malfunction first, and i don't have access to a test gauge.

that's what i was thinking. couldn't be that complicated on the inside, i just never took one apart or new if you could take one apart easily without breaking a seal or bending metal tabs, etc. figure some compressed air at a low pressure and like you said, a very small amount of oil. so far my gauges have been great without problems. i was thinking that maybe the boost gauge has a mechanical issue and was going to eliminate that, and figured while i'm at it, i should perform maintenance on the other gauges, seeing as they're 5 years old now.
