because the crankshaft pulley has some slack ...

Hello, today I went to change the distribution strap to my Ford Fiesta, 1.4 TDCI, I have disassembled it and I have seen that although the belt had 80,000kms I was new so I am waiting 10 or 20 thousand km more, well to the grain, someone because the crankshaft pulley, where the accessories is going, PQ has some slack for the key? Another thing starts the car with a wheel lifted from the ground and I have ignited the light of the ABS, and it does not go out, which may have happened, I hope I have not loaded the ABS cable ... Thank you and greetings for everyone ...

Hello, look I have disarmed on several occasions and yes, the guide is wider but has no implication in operation. What is relevant is that the crankshaft pulleys, especially those of diesel vehicles come with a rubber absorber, which is to avoid aciclisms in the crankshaft, that is, absorb the load of the different consumers (alternator, assistant direction, assisted direction. That the pulley has a useful life, and to know if it is in order, it is enough to make a transverse brand from the outside and go to the engine and stop it, and corroborate that the brand is not displaced. For the case of the ABS, it is simple, I detect you fail because the system detects engine in progress and turns a single wheel. The ABS controls the speed of the wheels independently to perform the necessary calculations and affect the electrovalvulas that the electrovalvulas that the electrovalvulat They handle the liquid pressures before an emergency braking situation. It is all in some cases to take a tour to take the 4 -wheel signal or do not erase the defects with any scanner for the intake of eobdii diagnosis of 16 pins.
Greetings!!

Ok, thank you very much, the ABS, it is a whore, it has never happened to me, the slack has to have some explanation, because the cars came with the pulley that fit fair, something better has to have to have that certain slack, I do not know if anyone knows the
scientific pq ...
