Oil for manual transmission: whether it's important or not?

Oil change in manual transmission-in? It is necessary? Some time ago gears were considered eternal, but now often hear about damages that are the result of driving with old oil.

Even if the manufacturer does not recommend oil change, Sometimes it is desirable to replace oil in the gearbox Sometimes amateur may submit a replacement oil in a box, in other cars is very difficult Wrong choice for oil
transmission can mean problems!

Why be smarter than the manufacturer? If the manufacturer writes that do not have to change the oil in the gearbox, whether it is worth exaggeration? definitely yes, and for several reasons. Najvažnije – sveže ulje može sprečiti veće kvarove.

Fresh oil lubricated bearings better

It will certainly confirm and users Toyota Corolla, in which the manufacturer has not specified change of oil in the gearbox. However, to avoid the need for replacement of bearings (mainly the fifth gear) after about 150 thousand. km, oil be replaced every even 60.000 km na! The driver will also prefer Opel Astre H i Zafira B, in which famous works (unfortunately, not durable) M32 menjač – zamena ulja je jedna od malobrojnih aktivnosti koje možemo da učinimo da se zaštitimo od problema, and there are many: worn bearings , cracked housing, broken teeth.

Do not forget to manufacturer, when he writes, "for the whole life of cars", does not mean 20 years and 500 thousand. km, but half of the time and distance. During Labor (or elapsed time) ulje gubi svoja svojstva – osim podmazivanja (You also need the right viscosity) It Must Be cool, protect against corrosion, etc.. Although there are better working conditions of the engine oil (lower temperatures, no exhaust gases), too old! The last argument for the replacement can be low price.

The right choice transmission oil is the basis of a good deal

Nadamo se da smo vas uverili u potrebu za promenom ulja. Can you do it alone? In most cases, gives, or mechanic can wait a few traps, causing problems even for professionals.

The first thing is to prepare the right oil. While badly chosen viscosity can avenge, na primer, problems in winter or improper lubrication during flight, use of the second API (American Oil Institute) than necessary can lead to the destruction of parts of the portable after several thousand kilometers! theoretically, the higher range (GL-3, 4, 5 or even 6), better prepared for difficult conditions (GL-5 has twice the anti-wear additive such as GL-4), however, use GL-5 oil in incorrect transmissions can destroy, na
primer, synchronous non-ferrous metal!

Some manufacturers do not specify the parameters of oil, they only give their standard. Proizvođači ulja su spremni za to – razvijaju proizvode koji ispunjavaju ove zahteve. some companies, such as Honda or (Lada Samara), recommended viscosity transmission oil 10W-40 ... (especially for transmission or engine!). If the transmission is lubricated with differential that has, na primer, limited friction, then you can request an additive LS (limited slip). We will not give specific brand recommended oil, but sometimes it's worthwhile to review the professional website and get feedback from the forum focused on the given model, because it may turn out that in certain cases some oils work better than others.

Oil is not always easy to change

Oil is bought, Time to trade. If all goes smoothly, it will take a few minutes. A pack be heated to a suitable temperature (just a few kilometers).

Each manufacturer has its gearbox design system. Menjač uglavnom ima dva čepa šrafa – onaj koji se nalazi odmah ispod polovine menjača služio je za dolivanje i punjenje. It was enough to put off and see if it is under your finger feels oil. During refueling of oil it is necessary to wait for the oil appears in the hole. At the lowest possible point of the gearbox was a drain plug.

Always begin by unscrewing the cap ...! If there is a problem with this (with the appropriate key, location ...) operations may be deferred. Ako ispustite ulje ranije – auto će biti onesposobljen.

NOTE: Do not place the screw on the gearbox if it you are not sure of the purpose !

Sometimes it's easy to find a plug for filling oil, na primer, vehicle speed sensor, sensor or the reverse relief, mounted within the housing.

Often you can not rely on the hole filling, because the amount of oil that
seeking a manufacturer located, for example, 1 cm below the hole (or replenishing oil from the top
notebook). Therefore, it is necessary to pour precisely measured amount of oil, not suggesting its level.

there are cars (eg. Ford) where there is no drain plug. Sometimes it may also turn out that it is necessary to unscrew the right cover, eg. or under the differential housing cover (Daewoo Lanos). The oil can be changed or suction, na primer, when replacing clutch (when you need to remove the transmission and can be rotated so that oil leaks, eg. near the shaft). Depending on the gearbox and models, there may be other surprises waiting: na primer, Opel proposes replacing the drain plug transmission, sometimes it is necessary to use a seal or additional elements (eg. Buckles to destroy, disassemble battery, cover, etc.).
Although the change of engine oil or automatic mode is more important than the manual transmission, this certainly should not be ignored!

Manufacturers often provide information on oil drain intervals in the gearbox. Could be 30.000 km, as well as 200.000 km na. If you do not have the right information, You can assume that oil will last until the end of transfer. However, worth it to pay attention to the often neglected reserves regarding the use of the car in difficult conditions. It turned out that, for example, in the city or while towing a trailer, theoretically untouchable oil must be replaced by new. Even if the manufacturer assumes that oil can not be replaced, we think it's worth it. At what frequency? It depends on the brand of car, transmission models, etc.. If there is no additional indication (eg. The tendency of the box that carries bearings), worth doing every 80-100 thousand. km or every 8-10 years.

Drain plugs sometimes have magnets on which accumulate chips. Treba da ih gledate – daje opšti pregled stanja prenosa. Closures may have seals (eg. copper washers) or it is recommended to use a gasket (Not very glue). Sipajte svježe ulje – u ovom slučaju morate ga pažljivo izmjeriti, or can be drawn in the chest by gravity from the tank, syringe is not required.
