XML FeedsDuratec Pulley Setup
By brad on Nov 3, 2009 | In Blog
Had a question a while back about how we handled the pulley setup since we were running with no AC and no power steering. It's actually pretty easy to do. The biggest trick was figuring out how to route it and keep everything turning the right way. We had to move the tensioner anyway due to clearance issues, so we moved the idler pulley down to near where the tensioner used to be. To cover the A/C compressor removal, we purchased an A/C delete pulley from Ford, which they sell for that very purpose, and installed it down near where the compressor would have gone. Finally, the tensioner moved up to where the PS pump used to be. For that we had to fabricate a bracket, which we designed to accommodate a standard length serpentine belt.
Here's what it looked like when we got finished. If you need details, just post a comment and I'll get more detailed info up for you.

For you tensioner, you took the tensioner from the lower left of the engine and mounted it up to the upper right (where the power steering pump used to be)?Then you took the idler pulley from where?
How much was the AC delete kit and what was the part number? If you have some better close up pictures that would be great.
I am close to firing up my Duratec on a test stand and this pulley/belt situation is one of the last hurdles.
Thanks,
Yes, moved tensioner as you described. The idler pulley is just to the right of the alternator, and I moved it down and to the left using want of the timing chain cover bolt holes. It took a longer bolt, and a spacer to get the proper alignment with the rest of the pulleys. I'm going to be traveling for the next week, but will try to get something up for you when I get back. 
Hi:I am in the process of finishing a 2.3L powered Lotus 15 Replica, and have a 2.0L Duratec on the dyno.
Some tighter photos of the new belt layout would be really appreaciated. Do you have sketches for the adapters, or did you make them on the fly?
Thx,

Hey, an update from the future! Now that the car is running, I want to let everyone know that there is a minor downside to this routing. It turns out the amount of contact between the belt and the water pump pulley is not as much as it should be. On start up, when the engine first revs on start before settling in at idle, there is a pretty loud squeal as the water pump tries to catch up with the rapidly accelerating belt. It's gone in about a second, and you never hear it again, but if you choose to follow this design on your Duratec, I wanted you to be aware of it. I'm going to contemplate how to solve it, but it's way down my list and I can live with it if necessary. By the way, belt dressing helped, but only for one start.Brad
