Is it possible to independently manufacture a short-stroke rocker?

Despite the fact that the cost of a short-stroke rocker is not so high, many people prefer to make and install it with their own hands, which, in general, is not so difficult to do. You will need very little to get the job done:

• a piece of pipe having a diameter of exactly 15 mm;
• the gear shift knob from the car for which the rocker is made;
• ball nut;
• backstage repair kit with axle and bushing;
• cardan from the steering mechanism.

The work itself on making a short-stroke link takes about two hours. The ball from the gear shift lever is cut off, its lower edge is adjusted so that a pipe can be installed, which will have to be properly welded. A nut is welded to the lower edge of the pipe and a ball nut is installed. After this, the cardan can be mounted to the gearshift lever.

Perhaps the whole process will seem somewhat difficult to some, but if it takes place under the “supervision” of an experienced mechanic/car mechanic, the success of the endeavor is guaranteed. It is possible to turn a car's standard rocker into a short-stroke one without the need to dismantle it. To do this, you will need to lift the fasteners of the “piece of iron” that extends from the gearbox to the shift lever itself. This is not to say that this procedure will make gear shifting truly sporty, but the free play of the lever will be somewhat reduced.

Gear shift drive rocker from Priora on VAZ 2110

What are the scenes in a car?

1. No vibrations on the gearshift knob;
2. New design of the gear knob with a gray insert to match the interior style.

1. Owners who have installed new parts notice a gap between parts 17 and 20. The metal disks 16 are not pressed against the spacers 16 and the lever 20 tightly enough due to the bushing 18. The problem can be solved by shortening the bushing by 1-2 mm.
2. Vibrations on the gearshift knob become less, but they do not disappear completely. They say that only cable shifters have no vibrations, but even there there is a rattling of the gearshift knob.

What feedback can you give about the new design of the gear shift drive? Does it make sense to modernize the design or sufficiently modify the existing one (for example, to get rid of the rattling of the gearshift knob, you can install a backlash-free universal joint and a fluoroplastic bushing)? By the way, look at other modifications of the VAZ 2110 in Priora.

Kinds

There are two types of scenes:

• Short stroke;
• Long-stroke.

There is no fundamental difference between the two types of units. The advantage of a short-throw is that it provides faster gear changes for a fraction of a second.

Do not believe those who claim that a short walk has a positive effect on dynamics. There is no connection between the rocker and the dynamics of the car. But the short walk has its advantages.

The work on installing a short-stroke rocker on the Lada Priora takes place in several stages

Lada Kalina hatchback Sport Logbook Replacing handbrake cables on the Luca ZTD

The decorative cover from the car gearbox lever and the knob are removed. Moreover, the knob is not attached to the lever in any way; it just needs to be pulled with some force. Remove the PP gearbox lever rod from the propeller shaft, to do this, first loosen the clamp using a key set to “13”. Next, you need to release the lever, having first released the locking ball (blocks the engagement of reverse gear). To do this, remove the locking ring (when removing, under no circumstances should you pull up on the lever). Remove the retaining ring and lever with ball and spring inserted into the plastic housing. The lever and rod are removed through the vehicle interior. If you wish, you can disconnect the lever from the rod for convenience, but this is not at all necessary. In order to remove the cardan, first pull off the rubber boot, after which the fastening bolt on the left of the cardan is unscrewed with a “10” key. We replace the removed Priora driveshaft with Kalina's driveshaft. Kalina's cardan has a longer rod, which must be shortened taking into account the type of short-stroke rocker being installed. In some cases, the cardan shaft may not go in completely, which will cause the gearbox lever to shift towards the handbrake. When shortening, about 1-2 cm is sawed off. Before installing a new cardan, lubricate it from the inside with lithol

The bolt, which has a cone shape, is easy to screw in; it is important not to overtighten. Next (preferably with someone's help) install the rod. The rod is also installed through the interior: one holds it in the cabin by the elastic band, while the second one carefully pulls it through. Reassembly sequence: - Place the rod on the rod of the new cardan. Assemble the reverse gear locking mechanism, lubricate the ball with lithol. Adjust the gear lever. Tighten the clamp on the rod. Important: Please note that if you start by assembling the reverse gear locking mechanism, then you may not be able to put the rod on the rod of the new cardan. This problem can be solved by shortening the cardan. Do not forget to put the rubber boot on the cardan.

Adjust the reverse gear locking mechanism

This is due to the fact that the link is adjusted, the locking mechanism may not coincide with the plate it clings to. To do this, the plate is removed and the engagement is painstakingly adjusted. The plate mounting bracket has a cutout into which the mechanism clings. Using sandpaper or a file, it is necessary to adjust and refine the hook for free engagement. Put the cover back on the gearbox and knob.

Do-it-yourself tuning of a VAZ 2109, manufacturing and installation of a short-distance rocker on a VAZ 2109

Lada 2101 Logbook Repair of master and slave cylinders of clutch VAZ 21011

The short-throw rocker is quite popular among car enthusiasts. This modern tuning is, first of all, good because, thanks to its size, it allows you to reduce the travel of the gearbox lever when changing gears. At the same time, gear shifting becomes much clearer.

The result of installing a short-stroke rocker gives an excellent result: clearly, quickly, pleasantly. But there are also two disadvantages: the price of a new rocker and the increased effort required when changing gears. Today, a short-throw rocker for the VAZ 2109, like for other cars, can be purchased at almost any auto store.

Moreover, the rather steep price does not stop car owners - many prefer to overpay once, but then enjoy the ride. In principle, the short-throw rocker in its design is not very different from the standard one, and after carefully studying its essence, making a short-throw rocker with your own hands will not be difficult. Moreover, this will take no more than half an hour.

Diagram of the operating principle of the VAZ 2109 short-stroke rocker

Let's look at the diagram. The OF points indicate the gearshift lever in neutral. To engage the gear, you need to move the rod (the point of attachment of the rod to the lever - point B) to the distance AB.

In this case, the knob of the gear shift lever (point F) will travel a distance FE and move to point E. Our task is to reduce this distance of movement of the lever handle. To do this, the lever OF is increased in length to point H. This is done in the place under the hinge by the length BD.

Since the PP box remains the same, the distance by which the hinge moves remains the same: AB = CD. Judging by the diagram, distance FE is much less than distance HG, which means a decrease in the distance of movement of the lever handle.

Now you don’t need to search around the cabin, both for the gear knob and then for the gear itself. Now about manufacturing and installation. You will need:

a welding machine, a grinder with a cutting wheel (or a hacksaw for metal), two metal fragments for extending the lever, a cardan from Kalina.

The work on installing a short-throw rocker on a VAZ 2109 takes place in several stages

Prepare a “Kalinovsky” cardan.

Remove the standard rocker from the vehicle.

Use a grinder to make cuts in two places.

Next, two fragments of the required dimensions are installed and welded: a piece of pipe and a piece of sheet metal. The short-stroke link is ready. Before installing it in place in the car, the rocker must be sanded and painted. When installing, adjust the position of the gear shift lever. By installing a short-throw rocker on your VAZ 2109, you will get convenience and comfort with your own hands and at minimal cost.

Comparison of short and long stroke

Car enthusiasts describe the difference in options as fantastic. The renovation dramatically improves ergonomics. The amplitude of movements of the gear shift knob decreases by two to three times, but the force on its tip increases. The increase is quite acceptable, since gear shifting occurs in an unloaded state with the clutch depressed and does not require any serious effort.

Some experts believe that an increase in the shoulder leads to an increase in forces on the gearbox rods and to additional wear on the gearbox. There is no statistical confirmation of this point of view yet. Unfortunately, it is not possible to order a short-stroke configuration from the factory. You must install it yourself at your own risk. AvtoVAZ does not approve of such changes in the design of the Nine.

Independent modernization of the design associated with welding the levers lengthens them, and the height of the gearshift knob above the tunnel increases by about 5 cm. Such alteration requires welding work and the involvement of an experienced specialist, for whom cutting the levers using a grinder, installing a pipe and a strip of the appropriate section , and also welding the levers is not difficult.

The adjustment changes the ergonomics, but due to the reduction in the strokes of the shift knob, it is not perceived as a deterioration.

Adjusting and installing a short-stroke rocker on a Priora

• VAZ 2110
• VAZ 2114
• Lada Priora

• Video publications
• VAZ tuning photo stream
• Operation and repair manuals

Tuning does not always mean installing a new body kit or shortening the Priora springs. Sometimes modernization helps improve driving comfort. An excellent example would be a short-throw rocker. VAZ owners know the “features” of the gear shift lever (GSL), which is not so easy to direct to the desired gear. The short-throw rocker on the Priora solves this problem, but we will tell you how to install it on the Priora and adjust it correctly.

The instructions in our material are also relevant for motorists who want to know how to repair and replace a conventional rocker. The instructions describe in detail the process of dismantling and adjustment, which is carried out for a factory part according to exactly the same principle.

Principle of operation

Study the diagram below to understand how the short throw rocker works. The lever is installed in the neutral position, here it is indicated by the points “O” and “F”. To start the transmission, you need to move the rod - it will connect to the control gear at point “B” - at point “A”. After this, the handle will move to point “E”. Repairs and subsequent replacements are carried out in order to reduce the distance.

This can be done if the lever extends to point “H”. This move will increase the distance. On the diagram, "A" and "B" will become points "C" and "D". Replacing the standard rocker with a short-stroke one allows you to reduce the movement of the handle. We've sorted out the theory, now we can start the repairs.

Replacing the gearbox slide

First, you should decide whether you will buy a ready-made short-stroke part or make it yourself. For Lada Priora drivers who have not upgraded components, we recommend choosing the first option. The instruction will be carried out taking into account modifications.

For work we will need:

• Two metal plates.
• Kardanchik from Kalina.
• Welding machine.
• A set of keys, including spanners.
• A grinder with a cutting wheel; alternatively, you can use a hacksaw.

Reasons for replacement

There are several situations when the owner of a VAZ 2109 has or wants to get into the design of the gearbox and specifically work with the rocker:

• Oil is leaking due to a damaged rocker seal. It must be replaced;
• The old drawstring was out of order;
• I would like to exchange the long-stroke for a short-stroke in view of its advantages.

Now to the question of when replacing or repairing the backstage is a necessary measure.

1. The backlash of the gearbox selector has increased significantly.
2. Gears change with difficulty, and when changing speed, extraneous sounds appear.
3. It is possible to change gears, but with a lot of effort.
4. Speeds change incorrectly. Instead of one, a completely different one turns on.
5. It is impossible to turn on all or part of the gears at all.
