What causes the speedometer cable to dry out?
When they assembled the speedometer cable at the factory, they filled the cable with bearing grease and then sealed both ends. This lubricant can leak out, deteriorate, or dry up over long periods of time. Without lubrication, the operation becomes noisy, but this is not the only problem.
Are there any problems with the speedometer on a vintage car?
Fortunately, problems with mechanically operated speedometers can often be resolved with a little effort. Here we’ll talk about how they work and common problems on vintage automobiles.
Is there a way to replace the speedometer cable?
Replacing the speedometer cable is one option, but there are two methods for lubricating the old cable that’s worth it to try first. For one method, they make a special speedometer cable lubricant that’s installed where the cable attaches to the speedometer head.
Why does the speedometer read higher when the tail shaft spins?
The faster the tail shaft spins the higher the reading on the dashboard. This type of implementation provides car makers with some flexibility to change calibration by changing the size of the gear that mounts on the transmission.
What can cause a speedometer to stop working?
The causes of an electrical failure could range from a short-circuit, to a blown fuse, to a physically damaged control module. The only way to know for sure if this is the cause of a speedometer failure is to have a trained technician test and diagnose the entire system.

What are the gears on a Ford speedometer?
Ford Speedometer Gears – Ford drive gears are machined into the output shaft on C3/C4/C5/C6 & AOD transmissions. You may need to remove your tailhousing to determine how many drive teeth your transmission has. 1 – This is a retrofit gear to allow the speedometer to function with 3.73 and 4.10 rear end gears.
How to replace drive shaft bearings on snowmobile?
Take your drive shaft out. Make sure all the pieces of the broken bearing are off of the shaft…. remove the remaining bearings (make sure to replace them all), and check the end of the shaft where the speedo cable goes in, chances are when the bearing went, the little brass colored piece was sheared off, and part of it is still in the driveshaft.
When to replace a bad wheel speed sensor?
1. ABS Light is illuminated on the dashboard Since the wheel speed sensor also monitors the anti-lock braking system on your car, it’s common for the ABS Light to illuminate when the sensor is worn out, disconnected, or has been struck by debris, which means you’ll have to replace the wheel speed sensor.
Which is more common PtO or jackshaft bearing failure?
The PTO-end driveshaft bearing, however, is a more common bearing failure than the jackshaft bearing. It is the one that is most exposed to the harsh conditions in which snowmobiles are operated.
Is the wheel speed sensor the same as the transmission?
The wheel speed sensor is different than the speed sensor attached inside the vehicle’s transmission. Its job is to record the actual wheel speed and report this data to the vehicle ECU which controls all electronic functions on the car, truck, or SUV.
