### How to take care of it to avoid premature failure?

No one doubts that the condition of the gearbox has a huge impact on the efficiency and performance of the entire construction machine.

In the season it is easy to forget about the need for **regular servicing** of the transmission, while taking care of basic operating activities can significantly extend the period of **trouble-free operation** of the gearbox.

What should you pay **special attention** to? We write about this in our **guide**.

### We start with changing the transmission oil

This is **fundamental**, but it turns out that many machine owners **wait to change the oil** until the end of the season, and this can **end very badly**. Remember that the machine works in **adverse conditions,** and the transmission itself must withstand extreme loads, so it is reasonable to increase the **frequency** of oil changes.

We also draw attention to the need to **use oil** that meets the standards of the machine manufacturer (information on this can be found in the equipment documentation or obtained from a service specializing in gearbox repairs).

Of course, it is also necessary to **regularly check** the condition of the transmission oil, and if the operator notices any **leaks**, he should report it immediately, as replacing seals is always much less expensive than repairing the entire gearbox.

Another important issue is **pressure control** on the clutch and converter, but this task is best left to a specialized service, and "by the way" the mechanic can check the condition of the **crosspieces** - if he notes any play, these elements should be replaced.

### Trifles that can cause a catastrophe

The trouble-free operation of the transmission is most influenced by the **operator** and he can notice **worrying symptoms** in time and report them to his superior, which will help avoid a troublesome breakdown.

The operator cannot ignore **noises** coming from the drive side, **jerkiness** when changing gears or **alarms** displayed in the cabin. Remember that even the most durable transmission cannot withstand improper operation.

### So let's remember a few basic rules:

- Never change the **direction of travel** when the machine is still in motion.
- Do not change **gears from off-road to road** (and vice versa) or engage four-wheel drive until the machine is stopped.
- Always select gears depending on the **load of the machine** and the terrain.
- Do not start a **not warmed up machine** abruptly - after starting in the morning, it is worth letting the engine work for 5 minutes at idle speed.

Failure to perform the mentioned activities always leads to the same finale: a **costly breakdown** and immobilization of the machine for a long time.

These are not particularly complicated rules and everyone can easily remember them, and finally, it is worth noting that the basis is **regular and reliable** servicing of the transmission.
