Main drive belt worn

Tilted the machine back on a 45 degree angle while a friend held it tilted I grabbed the pump belt and removed it and then removed the main drive belt by turning it and derailing it off track . but the new belts on using a reverse technique by rerailing the new belts on to the pulleys. pushing the main motor away from the spring tension made it easier . very simple staight forward job. similiar to putting a chain on a bicycle!
