The self-drilling design simplifies installation. Users can often achieve a secure fit without the need for additional tools like drills or pilot bits, thus speeding up the workflow. This ease of use makes 25mm tek screws particularly appealing to DIY enthusiasts and those who may not have advanced tool sets.
Smear a little gasket sealant round the cover flange and fit the new gasket to it. Make sure it is flat and straight.
We just discovered that one of the seals on our pumping system is leaking. Do you have any ideas as to what could have caused this, and can you offer some advice for selecting a good seal?
- In conclusion, the wheel hub oil seal is a critical component in automotive systems, responsible for preventing the loss of lubricant and contaminants from entering the bearing area. Regular maintenance checks and the use of high-quality replacement seals are essential for maintaining the performance and safety of your vehicle. By taking these steps, you can help ensure that your wheels run smoothly and efficiently for many miles to come.
Refit the distributor, ensuring that the rotor arm is exactly in line with the first mark. If not, withdraw the distributor and try again.


Material Code ISO 1629
The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s.

Start the engine and check for oil leaks.
Because synthetic motor oil can cost two to four times more than regular oil, talk to your technician about whether it’s the right oil for your car. If you live in a climate with super cold winters or very hot summers, or use your vehicle for towing or hauling, synthetic oil may be the best type of oil for your vehicle. Older engines could also benefit from synthetic oil, as it can help prevent harmful sludge build-up that some older engines seem to be prone to.
■Dispersants: This is your oil’s magic ingredient. It gives your oil the ability to absorb and hold solid contaminants so that they don’t damage the engine.
When the bore and shaft centers are misaligned, seal life will be shortened because the wear will be concentrated on one side of the sealing lip.
