Beware! Many people are under the impression that working on a sluggish rotary dial is nothing more than a matter of spraying it with a lubricating compound or penetrant. This is an invitation to make your dial a "dust magnet" due to the sticky nature of some penetrants. Also, the lubricant tends to dry and will eventually gum the dial, especially if it has been sprayed into the governor (speed-regulating) mechanism of the dial.
 
 

• The dial must be cleaned with a solvent that dissolves old oil and gum, and it then must be dried totally.
• The bearing surfaces of the dial operating parts must be lubricated with a pin oiler that deposits proper lubricant in small amounts. This is similar to lubricating a clockwork mechanism.
• The contact points of the dial must be burnished and mechanically adjusted.
• The speed of the dial must be tested and adjusted if necessary.
• The gap of the pulse contacts must be set properly.

All of our dial repairs are done on a special test unit that measures speed and "per cent break" to insure that your dial is operating properly when it leaves our shop. Repairs are guaranteed for one full year.
