Ford Repair Manuals | Check Poly-V-belt Ford Fiesta
Auxiliary units (the generator, a water pump etc.) of car Ford Fiesta are put in action a Poly-V-belt belt, in new engines OHC this problem carries out a belt 6K-Poly-V. Company Ford applies basically Poly-V-belts which especially flexibly move on radiuses of belt pulleys.
The hydraulic device regulates a belt tension. If at you the car with the air conditioner or the steering booster, the belt has other sizes, than in model with a base complete set. Necessarily carry in the luggage compartment corresponding Poly-V-belt on replacement.
V-belts perfectly perform the work only in the event that they have a necessary pretension: they should be tightened densely, but not so hardly. The deflection of a belt from 3 to 5 mm is normal by pressing the centre of a branch of a belt between two pulleys. Hardly tightened belts destroy in due course bearings of the generator, a water pump (depending on engine type) and the air conditioner compressor. Besides, hardly tightened belts are stretched and can tear further. On the contrary, sagged клиновые belts slip it is appreciable by creaking sounds. Most harmfully it affects the generator as thus it develops not enough current flow that leads to the big loading on the accumulator battery at trips on short distances and at start-up of the cold engine.
Sequence of works:
1. Check up a belt condition.
2. A hand some times turn a bent shaft. Only so you can reliably check up a condition Poly-V-belt on all its length. Often Poly-V-belts have one, but very deep crack. And if this crack, unfortunately, at visual inspection is on belt to a pulley, you will not notice it, that eventually can lead to heavy consequences, despite the carried out control.
3. If you have found out on Poly-V-belt following damages, at once replace it:
- non-uniform traces of deterioration on belt lateral faces;
- porous, shabby edges of a belt or a surface;
- cracks.
