A V-Belt drive is a very efficient method of power transmission (from 90 to 98 ) and has traditionally been thought of as very forgiving however proper alignment and belt tension are extremely important and can make a huge difference in MTBF (Mean Time Between Failure.) Do not assume that only a drive which is squeaking is slipping Belt
