Belt Troubles

[Chuck Irwin]

Hello all...I am a first time poster here just looking for some much needed help. I have a 90 lx which i have taken power steering and ac out of. Now the belt route is just crank around water pump under the belt tension around alternator and then around an idler pulley around the top center of the engine. Between the idler pulley and the alternator sits the tensioner pulley. There is a slight angle that I believer is causing the belt to slip off the tensioner and chew up the belt. I also have a seperate belt for the super charger but I do not see how that could effect this current problem. Is there any way to shim out that tensioner puller to bring it more in a direct natural path for the belt? Also is there a different pulley I can put on that tension that has edges on each side? Thanks for reading and any response.
