Oil drain plugs for motorbike oil pan
Oil drain plugs for motorcycle oil sump
The engine oil is one of the operating fluids that ensure the smooth functioning of the combustion engine. However powerful the oil may be, it ages. Over time, the lubricity and additives also diminish in motorcycle engine oil. Dirt collects in the oil circuit. Therefore a regular oil change is indispensable. In the TecBike Shop you can get a new oil drain plug and everything else you need to maintain your bike.
Why do you need a new oil drain plug?
As mentioned at the beginning, combustion engines require an oil change at regular intervals. Of course it is possible to suck out the old oil only through the filler neck. In the course of time oil binds a lot of residues. Eventually, the filter is no longer able to remove them all. Therefore a complete oil change ensures reliable operation of the engine. At the same time you contribute to the value retention of your machine.
At the lowest point under the oil pan is the so-called oil drain plug. The opening connected to it enables you to drain the used engine oil completely. In our shop you can get the screws in the colours
The oil drain plug is usually made of metal, in some cases also of plastic. It happens quickly, the screw tumbles into the collecting container when unscrewing. If you can't find it there anymore, you have to find a replacement. In order to ensure absolute tightness between the screw and the opening, a copper sealing ring is used.
Our screwdriver tips: Oil level check and oil change
In the engine the oil is an all-round talent. Checking the oil level is no less important: too much or too little oil causes damage to the engine. In addition: The oil consumption provides important information and indicators for the wear condition of the engine.
More complex than it looks: the engine oil
At first glance, engine oil may seem unexciting. Depending on the product, it consists of a base of synthetic or mineral oil. The recipe must not lack a true cocktail of additives. Only in this way is it possible for this operating fluid to fulfil its numerous tasks.
Connecting rod and crankshaft bearings, cylinder running surfaces and camshafts, all these components lubricate engine oils. At the same time they cool the drive unit. Usually the engine of the motorcycle is connected to the transmission as a unit. An oil bath clutch, as it is often installed, places special demands on the additives. Special additives prevent the clutch from slipping. They also ensure that the shearing forces of the gear wheels destroy the oil.
The oil level control
Well lubricated everything runs better. If the engine runs with too little oil, wear will increase. Insufficient lubrication can even cause engine damage. If you fill in too much oil, you slow down your engine. The oil slows down the parts moving in oil. Foam is formed and the oil loses its lubricity.
Furthermore, the oil pressure inside the engine increases. Defective seals are a consequence of this. It is also possible that it gets into the air filter via the ventilation of the crankcase.
The engine consumes oil during operation. This is completely normal. For water-cooled bikes the oil consumption should not exceed 0.4 l. The oil consumption of air-cooled motorcycles is slightly higher at 0.7 l per 1,000 km. In special cases, e.g. due to dilution of petrol, the oil level can increase. It is therefore essential to check the oil level regularly.
How do I measure the oil level correctly?
You measure the correct oil level when the engine is warm. In order for the oil to run back, the vehicle should be stationary for about five to ten minutes after driving and the unit should reach a temperature of about 80 degrees.
As an example: If the engine holds three litres of oil, the difference between cold and warm engine can be well over 100 sq.cm. Wet sump lubrication is widely used for motorcycles. With this type, the entire supply of lubricant is in the oil sump. A look in the manual will tell you whether you have to put the dipstick on for measurement or screw it in completely. Does your machine have an oil sight glass? Then you do not have these problems. No matter if dipstick or sight glass, for a correct measurement the machine has to stand straight.
Without a main stand, a second hand to hold the bike upright is helpful if you don't have extensive yoga experience. Rather rarely is dry sump lubrication used on motorcycles. In this variant the oil is in an extra tank. Here you also measure the oil level. Please follow the instructions!
Oil change on the motorcycle - this is how it works
If you ride a lot, you should keep an eye on the annual mileage when changing the oil. The oil change takes place either after a certain mileage or after a fixed time. This should rather be the case for occasional drivers. With older motorcycles, 6,000 km intervals are still common. Newer models, on the other hand, can easily tolerate an oil change after 10,000 or even 12,000 km. Common to all is the two-year change interval, if the maximum kilometers are not reached. Not only the lubricant should be changed, but also the oil filter. You can find suitable spare parts for oil changes in our TecBike range.
If the change interval for the engine oil is almost reached, it is advisable to change the fluids before the winter break. Fresh oil has a much better corrosion protection. In addition, the unused lubricating fluid does not yet contain any aggressive components which are produced by combustion.
The following items are required for the oil change:
- Appropriate amount of fresh oil t
- Measuring cup t
- New oil filter t
- New seal for the oil drain plug t
- Funnel t
- Tool for loosening the oil drain plug t
- Collecting vessel for the waste oil t
- If cladding parts have to be dismantled: the appropriate tool for this work t
- Torque wrench as well as the tightening values for the oil drain plug and possibly the filter housing t
- Cover for the garage/workshop floor
Oil drain plug leaking - what to do?
If the oil drain plug is leaking, oil is leaking. This can be seen in drops of oil under the machine. If the thread is intact, the first step is to change the sealing ring. Alternatively, you can replace the complete screw. If you meant it a little too well when tightening the oil drain plug and the thread has been damaged, there are several possibilities:
- As a quick emergency solution a suitable surface seal t
- Replacing the entire oil pan t
- Cut a new thread and then use a larger screw.
