The most obvious pairing coupling. Inverted coupling tends to resemble. In fact, there are parts that slightly thicker than the other side. Benchmark figures at the foot of the canvas. It should be reminded of the rules of pairs of coupling should check the position of the numbers in the foot pads. That's right, the number in the grip pads as standard. Pair must be to the outside of all. Do not be led into.
Logically, why should be installed to the outside with a benchmark figure in the foot pads. Thickest clutch friction material is only one side at the foot of which there are figures on the canvas. Medium friction and most powerful load on the existing part numbers. If installed upside down, the friction lining with certain events skid plate. Skid beginning of symptoms coupling will be forfeited.
Well, there is again a forgotten time replacing mechanical coupling. What ever check the thickness of the plate? If the thickness is less, certain symptoms skid. There is already a standard benchmark minimum plate thickness. Mechanical supposed to know. The size of the clutch plates are generally 0.01 microns. More than the mean thickness is reduced.
