+1 - you have to change the whole lot, the crankshaft pully has the crankshaft damper on it, which wears out over time, Ford ones seem better built than the pattern ones ive seen, so a Genuine Ford crankshaft pully is best
Gates make a kit with the belt, tensioner and idler pullys, which is cheaper than genuine Ford but decent and has a good rep
Overall the belt is a bad design and un-nessesarily long/ complex, it tends to rattle/ vibrate at tickover with the tickover being so low and the belt stretching over time
X-Type Jaguars use (almost) the same engine and gave a different (better) design of alternator pulley, that lasts longer before it starts rattling again, this can be fitted on a mk3 Mondeo but the alternator has to be slightly modified, - read it on another forum
A new pully/ tensioner/ belt set seems to last about 50k, its as if Ford was not bothered if it was to wear out outside of warrantee (but im not that cynical - am i
if you can sort out the Aux belt the injectors and the DMF, the mk3 Mondeo diesel makes a great car!
