The B49R Timken drive belt is a V-belt for trailer refrigeration units, listed at 52.1 in. long, 0.66 in. wide and 0.43 in. high. A V-belt drives its pulleys through grip on the sides of the groove, so it only works while the sidewalls hold on. Squealing, heat and a hard, shiny glazed surface mean the belt is slipping, and cracks across the back or sidewalls with a stiff, brittle feel mean the rubber has aged out. Check pulley groove wear, alignment and tension whenever a belt is changed, or the same failure comes back. A genuine Timken part from Pro Gear and Transmission.
