In the past they developed a lot of special tools.
Some tools aren't offered anymore by companies, so you should make your own tools like they did in the old days.
We find this a magnificent part of our hobby.
In this section we will show particular examples of tools for mounting and dismounting.
We cannot show all our tools: it is too much and mainly standard stuff, though it was not easy to find thread cutting tools such as die M11 x 1 in a cw as well in a ccw version.
That kind of tools should be looked for at old timer shows.

This extractor is the last within a series of mobylette extractors.
It is also a real challenge to make a clam shell with a small strong rim, that pulls the bearing off the crank shaft.
When making this kind of extractor you must be able to perform heat treatments on steel, too.
For most mobylette enthusiasts this is more than a bridge too far, because they miss the knowledge of basic metallurgy.
We use the same housing for this extractor as well as for the relay box extractor. You just have to change the shells. The round retaining ring with a inner diameter of 48 mm can be used for both extractors.

On the right a shell (collet) shape for removal of the crankshaft bearings.
These shells got the usual heat treatments such as quenching and tempering to make the shells extra strong. When you look at the small edge of these shells, that grab the bearing at the radius; you will understand why this material has to be so strong. We made some sets and happily all fitted perfectly. As manufacturing is quite time consuming, we will make those just for good friends or to swap against special spares. This was again a small expensive project that gave a lot of knowledge in return.

The pulley at the relay box is pressed on a conical shaft. For removal of this pulley you may need an extractor.
The extractor housing is interchangeable with the extractor housing for removal of crank shaft bearings.
However, the geometry of its shells at the spot, where they "grab the pulley", is differently sized and shaped.

On the right a set of shells for the relay box extractor.
These shells got some heat treatments such as quenching and tempering to make those extra strong. The end result was good and all fitted perfectly.

For ignition purposes a lot of tools have been designed.You will find some of these tools in the publications about ignition.

During summer 2017 we made several M1-extractors, because people were asking for those.
Recently we made for fun two special M1-extractors. The upper part has been made of bronze. Nowadays M1-extractors can be ordered in France at Solex-Motobecane.
M1-extractor Some people find those extractors expensive; moreover the shipment cost from France to abroad are considerably high. As the M1 extractor is available now, we will stop producing this type of extractor.

Here a short movie about how to use a M1 extractor from Jan Evert van Heek.
He is using a Pantin extractor and removal of a M1 cam has become a piece of cake now.


This tool has been developed to combine 3 different extractors in one tool.

∗ Crank shaft bearing extractor.
∗ M1-cam extractor
∗ Relay-box pulley extractor

By changing shells or the M1-cam head and connecting rings, you can change the tool´s application.
It may look a bit strange to combine all those extractors, as they individually work well, but we like a challenge.

The hardest part to make was - not the thread of the M1-part - but the connecting rings of the shaft and the M1-head.
You need a special tool to check the inner rims of the bushing on a lathe.

Above, you will find examples of other pullers, too.
Among those extractors a simple model for pulling off a M1-cam.

This extractor actually is a standard pivot bolt, but it makes removal of a plastic bushing easy. Of course you need different sizes of pivot bolts for different carburetors.


Inside of the relaybox there is a bearing in a blind hole. When dismounting the assembly sometimes the bearing with an inner diameter of 20mm cannot removed easily. This remover will expands its end inside of the inner ring of the bearing. Now removal is much easier.


When you must remove an old ball-bearing out of a hub of a rear wheel, then this tool can do the job.
For mobylette we use a 10mm or 11mm tool. The pin at the top lets expand this tool inside of the inner ring of the bearing.

This caliber will check the position of the coils compared to the flywheel. There must me some play, but not too much.
Nowadays this tool can be ordered in France, but when you are a handyman you could manufacture it by yourself.

This smart tool by Frank F. from Wageningen detects the exact moment of opening of the breaker points. We use it for checkimg the quality of the breaker points, while others use it for checking if a wire is conducting well.
It is a quite compact tool, which is working on a battery and it produces a nasty sound, so the condition of the contact is immediately clear.

For parts we use a lot of special tools. An example is an attachment for making a coil on a lathe.
With the right holder the center lines of coil and lathe are collinear.
This means several different holders for mobylette, but also for other marques such as Mosquito, HMW en MAW.

When compression is poor and the valve seat shows ugly imperfections, then this cutter can enhance the seat for the decompression valve.


Some people use a bolt, some rings and a socket of a socket wrench set.
We don't.


Marco van Berkel recently restored several AV42PR-mobylettes
He was not happy with how he had to remove the free wheels
So he used a big socket of 30mm. After a bit grinding he had made his perfect working tool.
Nice job!


Stan van Asten made a special key for the big nut with inner square of 10mm.
On the right: a picture of a piston stop, made from an old spark plug.
We do not use those at engines, which did not get their overhaul recently; then a clamp is preferable. However on trips this light tool is perfect.


When disassembling a relaybox this tool can be useful.
You have bolt it against your relay-box and now the assembly can be fixed in a bench vise.
Removing parts will become a piece of cake.
Karel Slenders, who made this tool, always uses the orignal VAR tools as his example.
