Corvette Speedometer Expert Repair and Restoration

Corvette odometer not working? Is the speedometer needle jumping or broken completely? Is your speedometer is noisy or squealing? Or maybe your Corvette speedometer is just looking tired? Whatever your speedometer issue, can help! We have all of the parts, equipment, and experience to repair or restore your Corvette speedometer. In fact, Corvette speedometer repair, rebuild, and restoration is a specialty here at Corvette Specialties of MD West!

Typical problems with Corvette Speedometers

Speedometers that are 50, 60, or almost 70 years old need to be rebuilt, period. It doesn’t matter what the mileage may be, time is what really contributes to many problems. Lubricants that were used when these units were assembled deteriorate and turn to a wax like substance. Most of the time when we disassemble a unit that has never been serviced, it is nearly dry. The magnet, or first worm, is turned by the cable at a high rate of speed, so parts will wear out. Gears will wear (see worn magnet below) and eventually strip, and failure occurs. Unfortunately, repair is not just a matter of replacing the second and third worm gears. Corvette owners who are familiar with the distributor side gear arrangement will understand it would be easy to change one gear, but the outcome is not good when replacing a driven gear without the main drive gear. The magnet is what drives these gears, and those magnets also wear out. We have the necessary special tools and calibration equipment needed to replace worn magnets. It is also important to thoroughly inspect the frame that houses the magnet. AC speedometer began using an oilite bushing for the magnet some time in the 1962 model year and we have the bushings and tools needed to replace it!  There is also a hole for the second worm gear that can wear, so when this happens we replace the frames. The frame must pass inspection to prevent premature failure.

Some owners are able to repair and service multiple components on their Corvette, but in order to properly service your speedometer you will need a magnetizer, demagnetizer, calibration machine, and specialized equipment to properly install the first worm (magnet). If you do not have the necessary skills and equipment to repair these units, then many things can go wrong. In fact, we often receive units for repair that someone has attempted to repair on their own! 

1953-1962

Corvette speedometer repair

1957 Speedometer. Note magnet is dry. Grease dries up, no lubricant. Needs rebuilding.

Let’s face it: These are old cars and unfortunately Father Time does not overlook speedometers. Any 1953-1962 C1 Corvette speedometers that have not been professionally serviced surely need it! Typical problems would include a loud squeal or a pointer that jumps wildly and often snaps, as the magnet spins in an aluminum housing without an oil impregnated bronze bushing. Typically the lubricant has degraded and it fails. Another common point of failure is the speed cup. C1 Corvette speedometers used a speed cup that was soldered together, though revision improved the design in very early 60’s. Simply stated, the shaft that holds the pointer becomes disconnected and the speed cup must be repaired or replaced.

1963 and later

Corvette began using a trip odometer in the 1963 model year. This is where the fun began. Commonly, the 1963-1967 Corvette speedometer would experience an odometer failure between 40,000 and 60,000 miles. The speedometer will continue to operate just fine in most cases. Some other issues that arise are a pointer that jumps erratically, an audible squeal, or a complete breakdown. Professional Corvette Speedometer service is needed. Our services are comprehensive, and will also accomplish the Corvette odometer repair.

Have confidence when sending your valuable instruments for restoration.

You may have a speedometer or tachometer that needs repair and not a restoration. The car may be a survivor, unrestored, etc. We certainly understand and will accommodate the owner in most cases. However, the 1953-1962 speedometers mounted in a case may be the exception. Often the outer case and inner plates will have paint that is flaking upon disassembly. In these situations, Corvette Specialties of MD West will media blast the old paint, and repaint these finishes. We do not want unhappy customers with paint flecks in their gauges!

Speedometer magnets

Pictured above are views of a good magnet, or first worm, and a worn part. Replacing second and third worm gears with a worn magnet will not solve the inoperative odometer problem!

Many different issues can cause odometer failure. This 1963-1964 Speedometer has a worn third worm hole in the dial. (Circled)

Speedometer Repair

This part is called a jewel plate. The jewel cup is in the center. Note the enlarged hole in the jewel cup. The speed cup that holds the pointer rides in this cup. Wear like this can contribute to a “wobble” in the pointer.

When sending speedometers for service, consider your tachometer. They are the same mechanism. They also wear and grease dries out. The main difference is the tachometer does not have odometers.

WHEN SENDING PARTS, PLEASE BE SURE TO INCLUDE OUR RESTORATION ORDER FORM.

IMPORTANT PACKING & SHIPPING NOTES: When shipping gauges and other items for restoration, please wrap the items securely! We suggest wrapping each item in bubble wrap individually and cushioning the wrapped bundles within the box with more packaging. When shipping open-face gauges, protect the gauge face by taping the gauge face-down to a piece of cardboard and wrap with bubble wrap. Note that some pointer bases may stick up beyond the edge of the face so the cardboard may need to have a small hole to accommodate it. Be sure to fill the package completely with cushioning material, especially the corners, as any movement within the box can cause damage. Do not use packing peanuts as they allow too much movement within the package. Insure your items for a replacement value you feel comfortable with. Please note that even if you insure your items, if the carrier determines the package was not packed properly they may dispute your damage claim.
