"Bavarian Motor Works (BMW)" a global name in the manufacturing of automobile, engine and motorcycle was founded by Franz Josef Popp in the year of 1916. It is the parent company of Rolls-Royce Motor Cars and is located in Munich, Germany. BMW vehicles are always known for their blend of luxury, comfort, power and performance. In exchange of a manual transmission unit, you may enjoy and take advantage of the power those BMW vehicles carries with themselves. All this is possible with the BMW clutch, a component in the drive train of a BMW manual transmission vehicle unit. The BMW actual clutch unit works because of the friction produced in between the clutch's pressure plate and engine's flywheel. The high quality and high performance BMW clutches are different for their BMW 3 series, BMW 7 series, BMW X3 SUV, BMW M3 Coupé and other BMW models for they depend on the number of friction discs pressed against a flywheel using springs.
Basically, a BMW clutch is connected to two shafts to perform the "clutch mechanism" i.e. to carry rotation either by engaging or disengaging the shafts of your sedan's manual transmission unit to the engine. The engagement of shafts refers to a synchronized and locked movement of the two shafts in which the transmission may start to rotate with the same speed as that of the engine's crankshaft. On the other hand, the disengagement indicates that the shafts are not connected and are spinning at different pace in which transmission may get separated from the engine. The disengagement of shafts allows your sedan to rest even though the engines are running and thus prove to be safe for the transmission of gears.
For the proper engagement or disengagement of the clutch, the users are given access to it through the left most pedal (i.e. clutch pedal) near your foot-step. When you step-on the clutch pedal then you are disengaging the clutch whereas when you step-off the clutch pedal then you are actually engaging the clutch. The pressure on the clutch pedal is conveyed to the clutch mechanism either hydraulically or mechanically through cable connection.
Why BMW Clutch fails?
- A worn-out friction material which is placed on the disc may let your BMW clutch to slip without transmitting power from an engine to the wheel.
- BMW clutch may not release properly due to sticking which actually puts a stop to your ride from going into gear. The sticking of clutch can be due to broken or stretched clutch cable, leaky master clutch cylinders, air in hydraulic line, misadjusted linkage, a hard clutch pedal etc.
- Sometime a wet clutch may have leakage of oil in it.
- Improper installation of release bearings may damage those fingers on a diaphragm clutch.
- Loose cover bolts when bolted to flywheel may cause wear and tear to the diaphragm.
- While disengaging the clutch pedal, your pilot bearing may sound growling to indicate a poor BMW clutch.
- Either due to the vibration in the clutch actuator mechanism or a poor release bearing you may hear a chirping noise.
- A squealing noise is audible due to a seized transmission input shaft bearing even when the clutch is working.
