10. Service Info

 

Speedometers on vintage mopeds are all mechanical type, not electronic. A driver or sender on the front wheel rotates the cable. The cable, with a spinning wire inside, goes up to the speedometer head. Inside the gauge a spinning magnet moves the needle. An odometer or mileage meter is also driven by the cable, with gears.  

Speedo families are heads, cables and drivers that have certain things in common. The head and driver threads are the same. The head and driver square cable holes are the same. So heads, cables and drivers within the same family all interchange. 

Speedo family name is the maker name plus the head and driver square cable holes.  

Square cable holes are a little bigger than square cable ends. A 2.0mm hole takes a 1.85 to 1.95mm cable, and a 2.75mm hole takes a 2.55 to 2.70mm cable. This is a source of confusion. 

Speedo drivers: On the front wheel is small gear box that changes the wheel rotation into the cable rotation. 

Speedo driver Side means what side of the front wheel would make the driver rotate the cable clockwise, viewed from above. Reversing the side by flipping the front wheel reverses the speedo cable rotation.

Speedo driver Type: Most drivers have the cable exiting below the axle. Most left side drivers are type d because they look like a letter “d”. Most right side ones are type b because they resemble letter “b”. But some type d’s are for right side, and some type b’s are for left. This is because the worm gear teeth can be wound left or right, like a left or right hand thread bolt.

Speedo driver Ratio means how many times the cable rotates for each wheel rotation. Larger diameter tires require higher driver ratios to achieve the same cable rotation. Smaller tires require lower ratios. The gear ratio is related to the angle of the gear teeth as well as the tooth counts.

Speedo cables can be different lengths for the same bike. Aiming the speedo driver more upward requires a shorter cable. Aiming the driver more downward requires a longer cable. When the front suspension goes over bumps, the speedo cable has to flex up and down. Aiming the driver 90 degrees to the suspension travel makes the least stress on the cable and the least interference with the suspension movement. Most newer bikes are that way. But then the cable hangs out a lot, and requires a fender eyelet to help prevent the long cable from getting snagged on things when parking or maneuvering.

1a. CEV Speedometers

CEV 60mm speedos, 0 to 40 mph, with 2.0mm cable hole

Speed testing: They are all tested on the same drill, for comparison of speed accuracy. The odometer accuracy never varies – it either works or not. It takes up to 3 minutes at 20mph to click off one mile. Each speedometer is tested for at least 3 minutes, some over 10 minutes all together. Once all of the 17 tested speeds are retested and verified, an average speed can be calculated. First the highest and lowest are ignored. Then the remaining 15 test speeds are added up and the sum is divided by 15 to give 23.8 average. You can see that most of the speedos tested at 23, 24, or 25 mph. The accuracy is an important factor in determining the price. The condition of the glass, face, and needle are also important. 

CEV-2.0/2.0 60mm round speedometers: 15 out of 17 were originally frozen. They have all been cleaned, checked, and lubed, and tested.

Markings: The brass end caps on VDO speedo drivers are marked with the tire or rim that they are geared for. 1970’s metal drivers are marked with the tire outer diameter (23, 22, 21, 20). 1980’s plastic drivers are marked with the rim size (19, 18, 17, 16). The tire OD’s are 4 inches more than the rim sizes, because moped tires are about 2 inches tall.

Batch marking: The marking that looks like a gear ratio is not. It’s some kind of batch number.

Tire marking: On some (21LH 6/61 and 23LH 23/5) the tire size marking disagrees with the measured gear ratio. 

Gear ratio: The red colored ratios are from direct measurement. Black colored ratios are inferred.

Side: Most (10 of 14) VDO speedo drivers are for the left side. Some (2 of 14) are for right side. Some (2 of 14) are for left or right side. On those the cable can attach in two places with opposite rotation. 

AE-88 driver, greased by a modified syringe

Greasing: The 70’s metal VDO speedo drivers had a grease zerk, but the 80’s plastic ones did not. One way to grease them without a grease gun or zerk is with spray chain lube. It penetrates in thin and then soon becomes thick. Another way is with a 5cc syringe and a 10-1.00 x 15 tall nut (for a Peugeot moped flywheel).

Huret-2.7/2.7 speedo family is on US models of Arciero, Bianchi (some), Demm (some), Garelli, Gitane, Motobecane, Negrini (some), Pacer, Snark (some), Velomec.
The speedometers in this family have a white face.

Huret-2.0/2.7 speedo family is on some US model mopeds but not many.
The speedometers in this family have a black face.

1. Huret-2.7 Motobecane, 2. Huret-2.7 60mm round MMI #H125F for Garelli. 3. Huret-2.0 60mm round, 4. Huret-2.7 48mm round

 

 

 

Good-used Huret-2.7 Motobecane speedos, unfrozen, lubed, and tested.

Long term testing: These were unfroze with acetone and re-lubricated with Tri-Flow. Then they sat on a parts shelf for four years in zip-lock bags. After that long, none had become stuck/frozen.

Huret-2.7 Motobecane speedometers: The cover is glass, so it resists scratching. Repeated exposure to sunlight fades the white background to yellow and the blue numbers to white. When the numbers are faded out the needle is still red, so speed can be estimated, like telling time on a clock with no numbers.

# price  miles   all are working normally unless noted

Good-used Huret-2.7 60 mm speedos, unfrozen, lubed, and tested.

Speed Testing: A hand drill was set to spin at a constant speed (by a stop screw in the trigger). Each speedo was spun for 30-50 seconds. The final speed was recorded.

Huret-2.7 60mm round speedometers: The test speeds all agreed quite well. These have great dampening, no jumping unless noted. The clear cover is glass, not plastic. So it does not get dull or scratched.

Preparation: All of these Huret drivers were initially frozen, tarry on the inside. Some were also tarry on the outside. Scroll down for the detailed procedure for unfreezing, cleaning and lubing. All of those listed for sale have been serviced and are ready for use.

Reversible: Most of these Huret speedo drivers are reversible. They can be used on either side of the bike, because the cable can attach to either end, resulting in opposite rotation. Most are on the left side. All have to rotate the cable clockwise, viewed from above the speedometer.

Derbi SL, SLE, TT speedometer cables: Many Derbi speedometer cables have a kink below the speedometer that causes the inner wire to break repeatedly. The kink is from the back of the “pancake” headlight pushing the speedo cable back. There is no easy remedy. As with any speedometer cable, any kink or sudden change in direction will eventually cause the inner cable wire to break there, because as it rotates it is being bent back and forth.

10. Service Info

 

Basic troubleshooting: Either the speedometer or odometer can work without the other, but the both need the cable and driver to be working. So if both speed and miles don’t work, it’s usually caused by a broken or slipping cable, and sometimes a broken or slipping driver. If either the speed or miles works, then then both the cable and driver must be good.

Stuck solid (frozen): Old speedometers become frozen where the cable enters. The grease there becomes sticky after many years. That causes the cable to break, or sometimes the driver. That is the main reason why 35 year old mopeds often have broken speedo cables. The other reason is the cable gets kinked. Speedometer drivers also become frozen after many years.

Unfreezing speedometers is done with drops of acetone and a modified allen wrench with a square end. Once the cable square hole can turn, it takes days or weeks and dozens of repeated applications of penetrating oil and rotation on a drill, before all of the stickiness is gone. If any stickiness is left behind, it can re-freeze a year later.

Unfreezing drivers: See below for the detailed procedure that involves soaking in acetone.

Greasing drivers: Most 70’s metal speedo drivers had a grease zerk, but most 80’s plastic ones did not. One way to grease them without a grease gun or zerk is with spray chain lube. It penetrates in thin and then soon becomes thick. Another way is with a 5cc syringe and a 10-1.00 x 15 tall nut (for a Peugeot moped flywheel).

modified syringe greaser

 

 

 


10a. Speedometer Tools

A. Acetone in a drip bottle with thin spout, for dissolving tar. Acetone is a powerful solvent that dissolves ink, tar, and paint. It penetrates into soft materials like rubber and vinyl, causing them to swell, distort, and become weaker. Lacquer thinner and MEK are similar to acetone. 

B. Tri Flow drip lubricant, for applying drops of oil. It contains banana oil and microscopic Teflon spheres.

C. 1.7mm cable end bent. This is for counting revolutions when measuring gear ratio on 1.8-hole drivers.

D. 1.9mm cable end straight. This is for spinning 2.0-hole speedos on a drill.

E. Modified allen wrench, ground to a 1.9mm square on the small end. This is for applying torque to a stuck 2.0-hole speedo, and for rotating back and forth once it is able to move, or around and around if it’s able to move in circles.

F. Tapered square end shaft, for spinning 2.7-hole speedos with a drill.

G. Modified allen wrench, ground to a 2.6mm square on the small end. This is for applying torque to a stuck 2.7-hole speedo, and for rotating back and forth once it is able to move, or around and around if it’s able to move in circles.

H. Small screwdriver for rotating 2.7-hole speedos.

I. Greaser made from a 5 cc syringe and a M10-1.0 x 15 hex15 tall-thin nut (for a Peugeot flywheel). It was pure luck that the nut threaded tightly onto the smooth, tapered plastic spout. Of course, this is only for M10-1.0 thread speedo drivers, which fortunately is the majority.

 


10b. Unfreezing Huret speedo drivers

1970’s Huret speedometers and drivers become frozen (stuck solid) after 40 years. Other kinds do also but not as much. Even new speedos and driver become frozen, because the Huret grease decomposes into hard sticky tar. Out of a sample of 30 new and 10 used 70’s Huret speedo drivers, all were frozen solid.  

Speedo drivers soaking in acetone

Ten frozen Huret speedo drivers were soaked in acetone in this sealed glass jar. After 17 hours they were removed and tested. 8 out of 10 were able to move, but 2 were still stuck solid. Those 2 were re-soaked with a new batch of frozen ones.

Acetone breaks down hard insoluble tar that is like taffy, and makes it less sticky and more soluble in diesel fuel or gasoline. When first removed from a day of soaking in acetone, the tar would ooze out like warm peanut butter when compressed air was applied to the cable hole. But after 20 minutes, that same peanut butter re-solidified, as the acetone evaporated out of it. So they need to go into the diesel fuel bath right after the acetone bath, rather than drying out first. They also need rotation to spread the solvent to all areas, like stirring.

The 8 unfroze drivers were then soaked in diesel fuel along with 7 others that did not need an acetone bath. The diesel fuel dissolves the loosened tar visible on the outside, as well as some soluble tar on the inside. After 2 days of soaking, 11 out of 15 moved freely, but 4 were still sticky. Those 4 were returned to the acetone bath pickle jar. The rest were brushed, cleaned and then blow dried with compressed air. 

While waiting to be greased, 1 of the 11 drivers refroze and 2 became sticky, as acetone evaporated from the grease inside. Those 3 were returned to the pickle jar of acetone.

Greasing with a modified syringe

The remaining 8 clean and free drivers were greased with a modified syringe, made from a 5 cc syringe and a 10-1.00 x 15 tall nut (for a Peugeot moped flywheel). Each driver took 0.2 to 0.6 cc of lithium grease. The syringe has to be squeezed really hard with both hands. The grease goes in slowly. The gears are rotated in between squeezes to spread out the grease. Soon the old black grease and solvent oozes out from the thin gaps, like on the left driver in the above photo. The feel goes from gritty to greasy as the new grease pushes out solvent and grit.  

The last step was straitening the fingers as needed, with a needle-nose pliers.

17 stuck drivers became 8 ready to use drivers. For the other 9 the entire process was repeated, as many times as necessary. This is how new and used 1970’s Huret (and others) speedo drivers are refurbished in preparation for sale.
