The different components of the Mehari transmission
An essential component for all vehicles, the transmission plays an indispensable role in the smooth running of your car. It fulfils several functions, the main one being to transmit the power developed by the engine to the wheels so that the vehicle can move. It is made up of several complementary sub-assemblies: the clutch, gearbox, drive shafts and hubs. For a better understanding of each of these components, you can consult our various technical diagrams
(in French). They will help you to visualise the assembly of the various parts and accessories that make up the transmission, and will help you to find the right reference for your needs.
A key element in the engine/gearbox relationship, the clutch temporarily disengages the engine from the transmission when changing gear. The Mehari clutch has undergone a number of changes over the course of its history, with two main models: the 'old model'
clutch, which was fitted to these cars until 1982 and featured a 3-finger mechanism, and the 'new model'
clutch, which incorporates a diaphragm mechanism for greater comfort and flexibility. To select the right Mehari clutch kit for your car, visit the dedicated section of our technical website
Directly coupled to the engine, which transmits its motive power via the flywheel and clutch, the gearbox enables the driver to reach the desired speed by selecting the corresponding gear or gears. The gearbox on the Citroën Mehari has 4 gears, including 3 synchronised gears and a reverse gear. The 4th gear, initially called the "overdrive", is marked with “S” (Surmultipliée). With the exception of the 4x4 model, which had a specially designed gearbox, the gearbox on the 'classic' two-wheel-drive Mehari underwent only minor changes, mainly to the splines on the drive shaft to adapt to the different clutch models.
The function of the drive shafts
is to transmit engine power and torque from the gearbox to the wheels. Unlike the 2CV, which had several generations of drive shafts (heterokinetic with double crossbars, then homokinetic with ball joints), the Mehari was only equipped with the second generation, which appeared on the 2CV in 1967. These are ball-joint driveshafts, also known as bearing joints or constant velocity joints. The Mehari universal joint is made up of two main parts: the outer driveshaft
(on the wheel side) and the inner driveshaft
(on the gearbox side). These two parts fit together to form the complete transmission shaft to each drive wheel. They are fitted with various cardan gaiters to protect them from dust or dirt and maintain an optimum level of lubrication. These different cardan shafts and their accessories (gaiters kit, individual gaiters, pins, grease nipples, etc.) are available on our site. We also offer a video tutorial
to help you change your Mehari drive shafts quickly and easily.
The final component of the transmission is the wheel hubs, which transmit the rotational movement of the drive shaft to the wheel, minimising friction between the running gear and keeping the wheel straight and fixed as it turns. They are made up of several parts, including specific bearings
for the front and rear wheels, sold in kit form or individually, bearing fixing rings, nuts, studs and drum plugs.
An unrivalled choice of parts and accessories for the Mehari gearbox
Our site offers you 3 references of completely refurbished gearboxes
(ref 1013101, ref 1013102 which differ according to the type of brakes fitted to the car) but also multiple parts for the majority of parts that make up the Mehari gearbox: various gearbox shafts (primary shaft, sliding gear shaft, gear shaft) as well as bevel gears, forks, differential bearings, differential spindles, pinions, synchro rings, levers, bearings, gear levers, end bearings, dismissal wheels and other references such as the gearbox rear plate or various gearbox oils specially adapted to the mechanics of the little Citroën.
Everything for your Mehari 4x2 or 4x4 transmission
In our online shop, you'll find our full range of Mehari transmission products, including our best-sellers at attractive prices. Whether original or MCC-made, each of these parts complies with Citroën's technical specifications. Although they are mainly intended for the Mehari 4x2, all these parts can also be fitted to the Mehari 4X4. Indeed, even if the 4x4 model has certain specific features, such as a longitudinal drive shaft that passes through the chassis to drive the rear wheels, the spare parts that make up its transmission are very similar to those of the two-wheel drive Méhari. Only a few elements are characteristic of the Mehari 4x4, such as its gearbox and larger wheel bearings, as on the 2CV AK400 van or the Acadiane (76mm diameter instead of 72mm).
