i have put my alternator belt on and someone said it looks wrong way - but others have said it seems right - which way is right???






the engine is a 1.8 silvertop zetec (phase 2) with a 1.8 pump

doin me skull in! so thought i would ask once and for all which way is right cos some have done different ways!!

many thanks

can you see on the belt pattern and the pattern on the pulley on the water pump? so if the pump pulley is flat it will take the back of the belt like the first one, but if it has a v or somehting simalar in it it will be the inside of the belt

Both. But providing the pump came from a 1.8 escort and not 1.8 mondeo the second one is right.

if its a vee belt then right diagram,if a toothed belt I assume its toothed both sides then left is possible.

Because your not using a more simple set up than on the car you use the one to the right. This requires that you replace the mondeo water pump with an escort one and change the flat pulley to a v grooved one. My original answer both wasn't strictly correct as although with the original pump you'd need to run it the otherway it probably woudl'nt tension properley without the original set up.

its a 6 groove belt - the pump is from a escort - just need to know which way round the pump should turn on the escort i suppose then - if its over the top (IE in the triangle figure on the right) i will need a new 6 groove v belt pulley as the one i have is smooth backed.. engine is from an escort not the mondeo

The config is as per the photo I posted also see http://www.zetecinside.com/xr2/stepbystep.htm#step3

ok so i think thats sorted then - escort pump you need to go in the triangulated diagram on the right

mondeo pump like on the left..

mines an escort so i have bonged it up - lol... wheres me check book - again!
another job for the list...

thanks chapsters...

You couldn't run it like the one on the left, nowhere near enough belt contact with pulley.

Irrespective of the correct pump rotation the belt should be as per RHS to give decent friction angle (or whatever you call it). Then you need correct pump to rotate that way round.

Can you remember what the configuration was in the donor car? (assuming you havent changed anything).

i didnt have a donor car - i swapped the engine and the pump came with it - a not very good mondeo pump - so using advice got the escort pump - BUT - the pulley i didnt know was different or that the internals circulated tuther way round - i do now!

live n learn - just ordered pulley from jennings - £16 next day delivery.. not bad me finks..
