does it mean that when u dont change the pulleys the main bearings wont fail????
The crank pulley acts as a harmonic dampener. That's why the extra weight is on there on the stock pully. By changing it to a lighter one you are reducing the dampening and as a result the main bearings and crank journals are the first ones to feel the brunt of this.
It won't happen over night.......but it will happen!
every mod has its own costs... wear out certain parts faster than standard... this is just my thinking.... plus all depends on the driver's style of driving as well.... if u drive the car hard all the time, something will fail sooner as well.... i just feel that opinions stated in this thread are scaring people away from doing it.... two exact cars have the same exact mod, does that mean that those 2 cars will have the exact problems at the exact time? if not y???? if the answer is the same as mine, thats y i would always use the word "may", "should", "perhaps". Nothing is for certain. Yes, the bearings may fail, sooner than using the standard pulleys, but who knows when?????????????????
