When is it necessary to change the transmission oil on a scooter?
Due to the fact that the scooter gearbox endures enormous loads, it must be maintained regularly.
After all, after a certain mileage, the transmission oil becomes saturated with various metal particles, and a sediment also forms in it. All this leads to a deterioration in its physical condition and properties, which means that it will no longer provide the necessary protection, and the part will fail in the near future. In principle, the frequency of replacement, as well as the class of oil, is indicated by the manufacturer, and it is these recommendations that should be followed. However, if we take an average, the frequency of this event should be about three thousand kilometers. What about running in equipment, then this operation should be carried out a little more often. The first time - after three hundred kilometers, the second - after a thousand, the third - after the mark has passed 2000 km, and then every 3000 km or once a year if the equipment is not used very often.

Replacing scooter gearbox bearings
In most scooter models, bearings are located in the same places; let's give an example of removing and installing bearings on a Honda Dio. The first step is to pull out the old bearings that are tightly pressed into the gear housing. In most cases, you will have to find a puller to remove it.
It is very important to carefully remove old parts and not touch important parts of the gearbox. On the Honda Dio scooter, three bearings are installed in the gearbox:
- on the body;
- on the intermediate shaft;
- on the gearbox cover.
It is extremely important not to tear the gaskets on the gearbox; they are extremely difficult to find in stores. Otherwise, you can make it yourself from paranit or thick cardboard
The replacement process is carried out as follows:
- We place the scooter on its side for better access to the gearbox, if necessary, remove the plastic;
- Afterwards, the old bearings are dismantled;
- Installation of new ones is carried out by preheating the seat, while the bearings themselves need to be cooled;
- We check the integrity of all gaskets, if damaged, replace them, do them yourself, or fill the gasket area with high-quality sealant.
- In the next 100-300 km after the replacement, it is recommended to change the oil in the gearbox.
Problems when paying with bank cards
Sometimes difficulties may arise when paying with Visa/MasterCard bank cards. The most common of them:
- There is a restriction on the card for paying for online purchases
- A plastic card is not intended for making payments online.
- The plastic card is not activated for making payments online.
- There are not enough funds on the plastic card.
In order to solve these problems, you need to call or write to the technical support of the bank where you are served. Bank specialists will help you resolve them and make payments.
That's basically it. The entire process of paying for a book in PDF format on car repair on our website takes 1-2 minutes.

Gearbox design in the T4 scooter
The gearbox consists of a set of gears, which are located in a common housing - in the crankcase. Thanks to the presence of the crankcase, all parts are located compactly. The crankcase protects all elements from mechanical damage and contamination, providing good lubrication of gearbox parts.
A gearbox is necessary to adjust the speed of rotation of the shafts down or up. On a scooter, this element is located between the secondary clutch shaft and the wheel.
The gearbox is divided into primary and secondary gears:
- The primary gear is the first and second gears.
- The secondary gear includes the third and fourth gears.
Both gears always consist of two gears - one large and the other small.
There is a hole in the gearbox housing for draining and filling fluid. The filler plug is just a regular bolt and washer. Transmission oil is poured into the scooter. It is advisable to check the fluid level in the crankcase once a month.
If the oil level has dropped or is completely absent, the gearbox begins to make an extraneous noise. Extraneous noise is produced by worn gears with a small amount of lubricant. And this will lead to wear of gears, bearings and bushings.
Draining the oil and flushing the gearbox
So, having selected the right lubricant for the regulator, you can begin to drain the old oil. Changing the scooter oil in the gearbox is carried out when the scooter is warmed up. To do this, it is enough to ride a scooter for 20 minutes before the change process. The heated liquid becomes more liquid, and this will help quickly drain the waste along with dirt or metal debris.
Draining the oil and flushing the gearbox:
- Wipe the drain and filler (bolt) holes with a clean rag.
- The filler hole is located at the rear of the power unit.
- Unscrew the nuts from the filler bolt, and then from the drain hole.
- Substituting an empty container, drain the old liquid.
- While the old oil is draining, wash the removed nuts and bolts in gasoline.
If metal particles are found when draining the old oil, the regulator housing should be flushed. To do this, remove any remaining lubricant from the crankcase and fill in transmission oil to flush it. The viscosity of the flushing fluid should be higher.
To flush the gearbox housing, you must:
- Tighten the drain bolt and then the filler hole.
- Start the power unit and rev it up a little.
- Drain the washing mixture.
- Tighten the drain hole.
This completes the process of draining the old fluid from the scooter gearbox. Changing the oil in the gearbox of a 4t 50q scooter is completed by filling in new fluid.
Filling with new oil
After draining the old lubricant and flushing the gearbox system, all that remains is to fill the transmission oil. Moped manufacturers recommend using the following modifications 75W90, SAE 80W90, 85W90 with API quality class: GL-4; GL-5.
The required volume of lubricant is always indicated on the gearbox. Use a large syringe to take the required amount of oil and pour it into the filler hole.
If you don’t have a syringe, you can simply fill the liquid to the lower level of the filler hole. The vehicle must be in an upright position when filling the oil. After pouring oil into the T4 scooter gearbox, wipe the filler bolt and plug dry. Carefully tighten the filler bolt and check the tightness of the connections.
In conclusion, I would like to note that the long-term performance of the scooter gearbox depends on regular maintenance such as timely replacement of transmission fluid.
