Idler Pulley disaster

[pthumbug]

My truck is a 94.5 f-250 with a 7.3L. No A/c.
The Lower Idler pulley, Just below the tensioner, ate itself. I was only about three miles from a NAPA so I limped in and got a new pulley. The problem is the pulley they sold me is smooth, no ribs, yet the way the belt leads I think it should be a 7 rib pulley. (The original was lost off the road) Can anyone look at there set up and give me some advice... I put this smooth pulley on and drove home but I think I've got the wrong one???
I'm supposed to run about 200 miles North tomorrow but now I'm a little nervous about having to walk home in the snow.
Thanx in advance.

Thank you for the info. I ordered the ribbed one from ford and will switch the smooth one to the top. I guess it will be an adventure trying to get to the Ford dealer. Its about 15 miles. Do I have a chance? or should i just find another ride?
any thoughts.

you should be alright, but when i have a idler go bad at work or my personal stuff, just to be safe to replace all the idlers and tensior and make sure to check everything else i have had alt. lock up 5 days after a new belt install and there goes the cost of the belt. Good Luck

well I made it!! No problems. switched out the ribbed idler and also the smooth one on top. Have not done the tensioner but may do that next..

Thanx for your help.
