  Q: What is the importance of maintaining the tension of drive belts on Mercury Bobcat?

  A: The tension of the drive belts should be correctly maintained at all times. The number of belts used and the configuration depends upon the particular accessories with which the vehicle is equipped. Depending upon the extent of equipment, two or three belts maybe used. Typical configurations are: Inner- crankshaft pulley, alternator, coolant pump; Intermediate - crankshaft pulley, steering pump; Outer - crankshaft pulley, air conditioner compressor, Thermactor air pump (emission control). Tensioning of a drive belt is carried out by moving the accessory concerned, or in certain instances, by adjustment of an idler pulley. Tension all belts to give the specified deflection at the midpoint of the longest run of the belt when it is depressed with moderate thumb pressure. Regularly inspect the condition of all drive belts. Any evidence of fraying or small cuts will indicate immediate renewal of the belt. To remove an inner drive belt from one of the multi-groove pulleys, the outer belts will have to be slackened and slipped from their grooves first. Correct belt tension as follows: Distance between pulley centers up to 12 in (305 mm) deflection 1/8 to 1/4 in (3.2 to 6.4 mm), over 12 in (305 mm) deflection 1/4 to 1/2 in (6.4 to 12.8 mm).
