Hi, guys I have 55 Victoria and for the past 2yrs only when it starts to get cold the speedometer makes noise. Does it need lubrication? Thanks.

Yup. There's a plug on the back of it that covers a felt wick. Remove the plug and saturate the wick with 3 in 1 oil or some such. While you're at it you may as well remove the cable and lube it, too. 

Thanks for the info.

As above reply!  I've had to actually remove those spedo's, disassemble the internal mechanisms, and "soak" the "oilite" bearings; if you do, do so very carefully, as there are some delicate parts easily damaged beyond repair.

Those sintered-bronze "oilite" bearings are recommended to be thoroughly cleaned in solvent (I find that the quick-evaporating brake cleaner spray is very good at cleaning them; but, that spray WILL damage plastic parts; so, be very careful using it around the spedo), then "soak" those bearings in non-detergent Mobil #10 original oil, if you can find it.

Other oils may contain some paraffin wax which WILL clog the pores of the bearings, and dry-out much quicker again.  A proper oiling should last for another 50 years or so!

BTW, for calibration following a thorough cleaning and lube. rotate the cable input at exactly 1,000 RPM (using a calibrated mechanical tachometer) and slightly rotate the [internal] calibration spring, one way or the other, if necessary, to indicate 60 MPH at that 1,000 RPM input.

How it works: The input to the odometer is direct drive through appropriate gearing; the speedometer is driven through a directly-driven rotating magnet inside the steel "bell" which is coupled to the speed indicator pointer.  That rotating magnet induces a "counter emf" into the steel [acts as a very simple electrical generator] which causes the bell to want to rotate too.  The calibration spring provides a counter force to that rotational force on the bell. The rotational force is proportional to the input rpm's [speed], which is what gives us the proper indication with changing speed.

Hope this info. helps.
