powersteering pulley (i6 300)
 

Cause my powersteering pump was leaking, i needed to change seals, but getting pulley of was a bit problem. I tried getting it of the right way but ended with streched pulley.
Can anybody tell me where to get new one? I can only find pulleys for multi-rib belts and some v-belt type pulleys are for only diesel engines.
Does i6 300 have its own pulley or does it match with some other engine/model? Cause i live in Europe, it's a bit big problem to get a new or old one.

Without knowing many details about your truck, like year, 2 or 4wd, A/C or not, etc I cannot answer the question. But, I've attached two pages from the parts catalog that will let you answer the question - in a way. By that I mean they will tell you if the pulley you have was used on another vehicle.

But that won't tell you if you can get by with a different pulley from another vehicle. I suspect that Ford used different sized pulleys for the application. Like a 2wd truck might get a larger or smaller pulley than a 4wd truck which has more weight on the front wheels. So I looked to see what pumps were used in the various trucks. At first blush it looked dire as there were several pumps used, but then I realized that all had been replaced by one pump - FOTZ 3A674-A. And, yet the pulleys weren't changed, as shown on these two pages.

So, that was a long way around to say that you can probably get by with any pulley you find on a pump like yours. It may be a larger or smaller pulley, but it should work. However, if you find a pulley on a pump why not just try that pump and pulley combined?
