In parallel with material improvements, design optimization played a critical role in enhancing drill rod performance
The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
You may need to take off the air cleaner (See Air filter change ), which may also have pipe connections.

Halogen lights are in fact the most commonly used headlights on most cars. Their invention dates back to the 1960s which was as a solution towards generating light with limited resources. Just like the incandescent lights, halogens use heated tungsten filament to produce light. The filament is however encased in a bubble of halogen gas unlike the incandescent, as a measure towards improving longevity and performance. These lights are easy to manufacture making the manufacturing process inexpensive. Moreover replacement costs are also very low. Halogen lights can fit most cars of different models as they come in different sizes and shapes. These lights however do not provide the best visibility as the white HID bulbs and LEDs. Quite a large amount of heat is lost while using these headlights and hence wasted energy. Moreover, they are very fragile requiring extra care unlike the LEDs and HID
