Distribution

They told me that the new Ford K, in Argentina comes out with a distribution chain, or time as it is called in other countries.
I want to raise this issue, I personally do not share the use of the belt that replaced the chain. I would like someone with knowledge of the subject to explain what are the advantages of the belt over the chain, and the belt should change periodically while the chain and its gears are only changed when a general engine repair is made.
In my case, I had to work in an oil camp, where the trucks were walking all the time in the cross -country, the distribution cover, which was plastic, not being airtight, allowed the finest dust to enter, it locked the tensioner bearing of the belt, stuck and cut the belt into a mileage much smaller than recommended by the manufacturer, let's say one third of the milestone. So: What is the advantage of the belt?

Well, I explain you very fast so as not to complicate the difference from a belt is that it is echoing a rubber nylon which the day that passes you are stretching it comes the time that the tensioner reaches its end point and it is when stretched jump or the tensor loses its lubrication and it is The chain also has its district that many replace it when we repair the engine if but others and what the concentrary recommends is to change from a period of 90 to 115 depending on the car model but this chains stretch the pine nuts are weeled in the teeth and the skates are of a material called Vaquelita or Plastic tensioned by a tensioner or hydraulic or resolt depending on the vehicle model that is the difference and remember that they cannot do something eternal because if you do not imagine the vehicle emsablator, it will be

A belt is changed to 45 0 50 km as I say of the brand of the brand and the 90 to 115km chains but many also change them before for the reason for starting the vehicles, picing rubbers or accelerating it suddenly this makes the chain last nothing and usually sound and change them before the recommended time
