Dooms. Most likley the drive belt is under so much pressure against the sheaves, dive it and see if it gets better, did you grease the secondary sliding sheave bushings?

Did you buy the new sliding sheave or just the spring/spacer kit? I try to check the sliding sheave bushing play on the input shaft before reassembly,the bushing is available seperatly. Sometimes I put 2 or more shots in, but if you overgrease, it does have a tendecy to throw the excess grease around in the engine compartment. Do you like the new "low end/tourque"?
