Hi all, Im new to the group here, but have been looking for a little while for info on my new, to me, 86 CJ-7. I found a sweet heart locally and picked it up for a project with my son, 13yrs old. Its almost all original with the exception of a lift and 33's, 237K miles. runs great.
Issue: I replaced the serpentine belt and the new one immediately started squealing. Ive tried belt dressing, nope. Adjusting the idler pulleys alignment, nope. Tightening/loosening the belt, nope. A little bar soap on the belt has helped but only temporarily.
Question: one of the idler pulleys is plastic, and one metal. The plastic one looks like its not original and is a little wobbly, minimally, and appears to have been melted slightly by rubbing on the outside washer/plate that is held by the mounting bolt. Is the plastic pulley original? and why would soap quiet the belt if the pulley is messed up???
