Largus fifth gear which is better

March 25, 2016 Lada.Online 125 583 21
Largus 5th gear ratios are excellent for those who drive the car mainly around the city, often with a full load. The shortcomings are revealed on the highway when you don’t have time to reach 100 km/h, and the engine speed is already at around 3000 rpm. You can get rid of the hum and howl of the engine and gearbox with the help of a simple modification: “replacing the fifth gear gear.”

Replacing Largus 5th gear gear

The design of the Largus transmission allows you to change the 5th gear gears without disassembling the entire gearbox or even removing it from the car. You will need a gear puller, a hair dryer and two screwdrivers. If you have the necessary tools, the process takes no more than 2-3 hours. Video instructions:

When replacing gears with their own hands, car enthusiasts most often encounter difficulties when dismantling a small gear. Removing it without a special puller is not so easy, because... it sits on the shaft using a thread locker. In this situation, a hair dryer can be useful; after heating, the part will easily slide off. Don't forget to fill in new transmission oil.

Preparatory work

According to Renault regulations, when working on the Largus gearbox, the nut washer and input shaft nut, the shift fork pin and the rear end bolt of the secondary shaft must be replaced. The cost of consumables for Largus is low. This is a plus for both Russian cars and Renault cars. However, as experience shows, most services do not do this, which can lead to other damage.

To replace the 5th gear gear you will need:

standard set of wrenches, sockets and pullers;
punches;
small screwdriver;
hammer;
rubber mallet;
means for cleaning and degreasing the surface of parts;
FRENETANCHE thread locker.

It is recommended to carry out all work on a special lift; if one is not available, drive the car onto a pit or overpass. Before starting work, disconnect the battery.

Reviews about 5th gear gears

Based on feedback from owners of the Lada Largus car, as well as reviews, trials and tests, we have compiled a comparison table:

PCH-5	Shifting to 4th gear	Hill climbs in 5th gear	Confident acceleration in 5th gear	Summary
0,892	Rarely	Confident, even with a load	from 50 km/h	Loud engine noise on the highway. Only for the city and with load.
0,820	Sometimes for fast accelerations	Confident, even with a load	from 60 km/h	The howl of the engine on the highway has become less, but you still get tired of it. When trips are more often around the city and less often on the highway.
0,795	During fast acceleration	Confident, but without a load	from 65-70 km/h	To switch to 5th gear, you have to accelerate a little longer in 4th. The hum and howl from the engine and gearbox are within normal limits. Ideal city/highway option.
0,756, 0,738	Often	You should add gas	from 75-80 km/h	The gap between 4th and 5th gear is significant. Minimum noise level from the engine and gearbox on the highway. Suitable for driving on flat terrain with occasional overtaking.

This modification is primarily used to reduce engine speed when driving in 5th gear. Fuel savings after such upgrades are not significant. If fuel consumption with PCH-5 0.892 was 7.4 l/100km, then with 0.795 it will decrease by 0.3 l and amount to 7.1 l/100km. If you expect that replacing the 5th gear of Largus will pay off in terms of gasoline savings, then you will have to wait several years.

How do you feel about this modification of the Lada Largus gearbox? Is it worth changing the 5th gear driven and driven gears? What gear ratios are best to choose? Let us remind you that you can increase the speed of the car in other ways, for example, by installing wheels of a different diameter. And to make long trips more comfortable, you can add an armrest.

Replacing Largus 5th gear gear

My account

The main faults are clogged teeth, wear of differential bearings, wear of forks, wear of synchronizers. A common malfunction is oil leaking through the oil seal and driving with a low oil level because of this. If you get to the point where the oil runs out, you don’t have to bother with repairs. It's cheaper to buy from a disassembly shop. You can often find badly knocked down gear teeth of the reverse gear: The drive oil seal is damaged during disassembly, so it must be replaced in any case.

The input shaft oil seal is pressed into the release bearing guide, and the input shaft bearing is also pressed into it. Therefore, the entire assembly is replaced; in addition, on old gearboxes, the guide usually has deep grooves from wear: It is better to replace differential bearings with high mileage, regardless of their condition.

Difficulties may arise when installing the differential. Normally you need to use a press. But you can do without it.

How to recognize a malfunction?

First, we press it in, applying blows, for example, with a rubber hammer to straighten the body, or carefully through a drift, until the differential sits, reaching the spring ring. To put the locking ring on, you need to push it down a little more, but knocking on it is useless.

Therefore, we compress a little on one side with a large vice; the compression will only occur on one side, but usually this is enough for the stopper to fit into the groove. At the factory, anaerobic glue and sealant are used to seal the box. If this is not the case, you can use a regular one. The rocker is a gear knob. With its help, you can select the Renault speed.

The need to repair the backstage occurs if increased vibrations are observed when changing speeds. In this case, it is necessary to inspect the condition of the ball joint. To dismantle the rocker, it is necessary to disconnect the exhaust gas exhaust system, the control drive rod, and remove the cover. After this, free access to the mechanism is provided.

The slide is fixed with bolts that can be unscrewed with the appropriate key. For this purpose it is necessary to dismantle the existing casing.

The gearbox is part of the transmission of cars. A few practical tips will help you avoid repairing the Renault Logan gearbox: Change the oil in the gearbox in a timely manner, it is the driving force of any transmission.

But when changing the gearbox oil, you need to carefully select it, otherwise you will cause even more damage.

Shift according to the maximum and minimum speed limits that are assigned to each gear stage. In first gear this value is up to twenty kilometers per hour, in second - up to forty, in third - up to sixty, in fourth - up to eighty, fifth - after eighty.

In winter, do not forget to shift the gear to neutral. Remove the computer, and then the mounting blocks on the left and right. Loosen the tension on the clamp holding the box control rod.

At the same time, note the relative position of the lever and the rod; in this case, reassembly is simplified. Slide the clamp along the rod and separate the latter from the lever.

Press the fastener of the speed sensor block with a screwdriver or a sharp object, and then discard the wiring harness. Take a screwdriver and use it to pry off the fasteners of the block with the wires that supply power to the reverse speed lamp switch. Take out the engine harness, then move it to the left or right so that it does not interfere with further removal.

Tighten a pair of mounting bolts for the TDC sensor mounted on the crankcase, and then remove the device. Press out the block fastener of the oxygen control sensor, and then separate the block from the clamp. Remove the transmission breather tube from the holder. Tighten the caliper mounting bolts on the front brake assemblies.

Reviews about 5th gear gears

Based on feedback from owners of the Lada Largus car, as well as reviews, trials and tests, we have compiled a comparison table:

We select the optimal gear ratio for the highest gear of Largus. A set of gears will cost about 3,000 rubles, and the craftsman will charge the same amount for replacement. However, the gamble is worth the candle: a faster fifth gear will reduce engine noise and make travel more comfortable.

Selecting transmission oil

Tranself TRJ 75W-80
The transmission determines the dynamic and speed characteristics of the vehicle. When the gearbox fails, vehicles lose their driving performance. In some cases, this may be the result of the transmission fluid losing its quality. For Lada, it is necessary to select oil that must match the brand of the automotive system.

Transmission oil is poured into the box, which is designed for the entire operational life of the vehicle. However, a number of car owners decide to replace them at 60,000 km. As a rule, Tranself TRJ 75W-80 is used for the Lada Largus gearbox. The oil level should be checked every 15,000 km. Replacement should be done with the car warmed up. It is not recommended to mix different types of transmission fluid on Lada.

Lada Largus

Over time, you get used to the shortcomings of the car you drive all the time. But there are exceptions to the rules. For two years now I have been using the Lada-Largus editorial station wagon and still cannot accept the heart-rending roar of its engine on country roads. On a long journey, you get tired of this tedious monologue, and the rising tachometer needle puts pressure not only on the psyche: you constantly think about increased fuel consumption. Judging by the numerous unflattering comments on thematic Internet forums, I’m not the only one who doesn’t like the too short fifth gear. Moreover, this problem mainly concerns the most popular passenger version with a 16-valve 1.6-liter K4M engine. Different boxes and main pairs are installed on Largus (see table). And in a passenger car with a sixteen-valve engine, fifth gear turns out to be the most high-torque. Even the van speeds faster in fifth gear. Although logically it should be the other way around.

The faster fifth gear primarily reduces engine noise, making travel more comfortable. But you won’t save much gas: the cost of a new pair of gears and the work to install them will pay off only after a few years.

Reliability jh3

The JH3 gearbox is considered a reliable unit, therefore it is still relevant in the automotive market. Car owners prefer cars with a structurally simple gearbox, partly because of its accessible and cheap maintenance. The disadvantages of manual transmission boil down to the lack of a high level of driving comfort.

The gear shift does not always occur clearly and quickly; sometimes there are jolts and jerking of the vehicle. Structurally, the unit has been fully studied, so even in the event of a serious breakdown, its overhaul will not be difficult. Usually the lever for switching from one speed to another becomes loose ahead of time, which leads to unclear switching.

Often, owners of Lada Largus with JH3 note the noisy operation of the manual transmission and a crunching sound when engaging reverse mode. Early wear of the synchronizers cannot be ruled out. If we close our eyes to some shortcomings, we will get decent mechanics that can go 200-300 thousand km without a single repair. There are known examples of cars that have covered about 500 thousand km on JH3 without a single repair. Much depends on your driving style and quality of service. The oil change must be carried out in accordance with the maintenance regulations.

WHAT IS GOOD?

The standard sixteen-valve box has both pros and cons. Among the advantages is the ability to provide dynamic acceleration and excellent elasticity. A car with a gross weight of nearly two tons and armed with only a 105-horsepower engine confidently stays in traffic, and in fifth gear it cheerfully picks up from 50 km/h - there is no need to shift often. On long hauls, sometimes you drive for several hours in fifth as if on automatic. It’s convenient, but you have to pay for it with increased noise and fuel consumption - and even when the speedometer needle has not even reached a hundred. Therefore, together with the specialists from our technical center, we decided to experiment with different gear ratios. After all, the design of the Largus transmission allows you to change fifth gear gears without disassembling the entire box or even removing the unit from the car. By the way, owners of Renault models (for example, Logan or Sandero), as well as Nissan-Almera, can similarly configure the top gear for themselves.

There are different sets of gears on sale, each of which will cost about 3,000 rubles. The craftsman will charge the same amount for a replacement. The beauty is that you won’t have to part with the car for a long time: a competent repairman can handle it in a couple of hours. Let's try!

Disassembling the differential

Now you can start disassembling the differential. To do this, remove the locking ring:

Then take out the glass:

We turn the box over, pull out the oil seal (hitting one edge of the oil seal will warp and then you can pry it up and pull it out), under it there is another retaining ring. It also needs to be dismantled; this ring is pressed by the differential spring washer. To make removal easier, you can clamp the differential gear and housing in a large vice. This will make it easier to remove.

Now the differential is held in place only by seating in the bearings. We put something under the box and knock out the differential, striking the shaft through a drift. In this case, you need to be very careful not to clog the slots. Or better yet, use a straightening hammer. Some people hammer this differential on a piece of wood until it knocks it out

The wide spring ring should be installed as shown in the picture; pay attention to this when assembling. It serves to ensure the required bearing tension

In general, there are two rings, the thin one is stuck to the gear:

We simply knock out the large bearing; in order to press out the small one, you need to remove the speedometer drive and the retaining ring:

We pull up the speedometer shaft with narrow pliers and then take out the gear:

Then we take out the retaining ring and knock out the bearing.

THREE FROM THE CASTER

Editorial "Largus" tried on three pairs of gears with different gear ratios. In addition to the standard fifth gear of 0.892, we sequentially installed sets of 0.820 and 0.795 (see table). On a 300-kilometer test route, including highways and suburban roads, they compared the difference in fuel consumption and accumulated subjective assessments, which are sometimes even more interesting for the car owner than measurement data. For reliability, the expert assessment was supported by measurements at the Dmitrovsky test site. Test results and comments are presented below, including photographs, tables and diagrams.

0,892. The basic version provides excellent elasticity. Fifth gear can be used from 50 km/h even when fully loaded. You rarely have to shift down - the traction reserve is enough even for quick overtaking. But the noise of the engine operating at high speeds is annoying, even if you are moving no faster than the permitted 90 km/h: on long trips you quickly get tired.

Summary. The basic version is good for those who move mainly around the city, often with a full load

0,820. The engine is no longer perceived as so elastic, but still within normal limits. You only have to shift to fourth gear for quick accelerations. Even with a full load and in fifth gear, the car easily overcomes climbs, and on horizontal sections it confidently picks up speed from 60 km/h. At the same time, it became significantly quieter at high speeds. The gain on fuel is insignificant.

Summary . A universal option for every day. Fifth gear is quite functional in the city, and driving on the highway has become more comfortable. We recommend that AVTOVAZ take this option as the base one.

0.795. My personal choice . Editorial "Largus" is rarely fully loaded, and on country routes I usually drive on roads with flat terrain. The number of shifts from fifth to fourth on the test route increased, but only slightly. When upshifting, I stayed in fourth gear a little longer before engaging fifth, and when overtaking, on the contrary, I began to shift from fifth to fourth more often.

Summary. Optimal for suburban highways, tolerable for trips around the city. If you load your car to capacity or drive on roads with long, steep climbs or frequent overtaking, choose the 0.82 option.

0.756 and 0.738 . We have not tested these options, but judging by our impressions of the 0.795 fifth gear box, they accumulate the shortcomings of the previous option. Elasticity will deteriorate, you will have to shift from fifth to fourth more often, and there will be a significant gap between these gears.

Summary . These options are convenient, for example, for driving on a flat and empty highway at a constant speed and rarely overtaking.
