I've done other lock cylinders, gauges and speedos of a similar design, but never that way and never a motorcycle. Typical for a power zener in an instrument gauge. There must be a trick or secret to opening a motorcycle speedometer. For those of us with electronic speedo heads or digital speedometers, there may be a recalibration function buried in the software. I took my Mercedes in to have the speedometer cable replaced at the dealer. If you find any, you may need to make adjustments because the calipers are pinching the speedometer cable.
I have a hard time watching some of these go by because I have seen and done the repairs for many of them and I want to reach out and help, but not at the cost of a liability suit. Thank you for such an excellent job. Lubricating a speedometer cable will always result in failure of the speedometer so do not attempt that 'repair. The internal inertia damper was opened, cleaned out and refilled to restore its smooth action. In the case of a small plate and bolt that holds the retaining nut in place, use the appropriate socket to remove it. If so, and if the plastic is something that can be glued back together with strong glue or solvent, you could chuck it into your lathe and part it off a short distance behind the bezel, and glue it back together after the repair. I know the Suzuki speedo systems operation quite well, and developed a commercial product to connect to them.
If it is broken or the edges are rounded, the cable needs to be replaced. Lubricate the new cable with lithium grease, spreading a medium-thick coat over all sides of the cable. That said, stay tuned because HappyWrench is going to do a. Especially if you purchase used wires, double check that the speedometer cables you purchased are the correct cables for your motorcycle. It's not a trivial installation and calibration procedure, although the gadgets themselves can be had for a hundred bucks or so.
If you do it in less than that, you rushed and you are not going to be happy with the final result. One has two options, speaking from my experience many years ago. These standards say that a motorcycle speedo may not show a speed lower than the actual over-the-road speed, which sounds like a good plan. Connect the retaining nut on the cable housing to the back of the speedometer gauge. Do you see the chrome bezel or rim around the bottom? This is a very slow, very carefully done process. Truth of the matter is though, that speedometers from Harley were not really designed to be user friendly when it comes to doing a repair.
For those less familiar with speedometers and how they work — basically there is a single cable that runs from the back of the speedometer to either the transmission or front rotor. Am I to understand that as long as the word bike or car is used, we cannot help him? Similarly, if you have a spare speedometer sitting around, you can do the same process of elimination by attaching the good speedometer to your cable. There is no need to hit it very hard. I have this morning received the gauges you have restored for my Kettle and have just unwrapped them. But permissible error in the other direction is 10 percent plus 4 kph. They said the variance was to ensure an aftermarket tire that may have the same tire size but differ in true height would not cause the speedo to read pessimistically.
Trust me, going to the service department and complaining that the speedo is wrong falls on some seriously deaf ears. He studied architecture at Taft Junior College. As the tire wears and gets smaller, it rotates faster for a given velocity over the road, and the speedo spins faster. Once you've got a percentage to work with, plug the calibration device into the speed sensor—in Fenske's case, attached to the transmission—and follow the instructions to program in the correct amount of compensation. Think about it, you buy a new part, get the warranty behind it a year and they do not worry about it. Connect the gearbox-transmission side of the cable housing, turning the retaining nut clockwise until it seats.
Practical Machinist is the easiest way to learn new techniques, get answers quickly and discuss common challenges with your peers. You'll need to get a hand puller to do this to get into the unit most likely. A six jaw chuck works well. If rust or corrosion has accumulated, the speedometer needs to be replaced. And of course other cars and bikes in the two left-most lanes were overtaking me by a good 10 mph.
Last weekend I pushed my Triumph out of winter storage. I am amazed at how good they look. Carefully work your way around until it is solidly back in place. It is possible to apply enough force to crack the plastic speedometer housing and then you will be up a creek without a paddle. Locate the lower end of the speedometer cable where it attaches at the front wheel hub.
The crudely regulated rail comes out of the cluster gauge and powers the 3 wire hall effect speed sensor down near the gearbox, the voltage is 9v or 10v going from memory but it is not critical. Personally I think it does, but like I said I'm not a moderator so it's going to be their opinion that counts here. It will usually pop off before you've gone much more than about a quarter of the way around. It's usually pretty simple to change the gears.

You'll need to buy a speedometer recalibration device to perform this fix—Fenske uses one called , but you can find to suit your application.
