2 ways to fit a drive belt
1) stretch version
2) adjustable swivel gate on motor
1) the belt is placed centrally on the small pulley then fed on to the large pulley wheel up to the point where belt looks to small to fit (usually the last 6 inches) you now grab the large pulley arms (with gloves) and now turn the large pulley wheel to make the belt STRETCH on the last bit.
2) the belt is placed around the large pulley the motor gate and motor bolts are slackened then MOTOR pushed inward the belt is then fitted around the little pulley, the belt is then re-tensioned by pulling the motor outward you tighten the gate bolt then tighten the motor bolts.
this is same as adjusting a dynamo/alternator belt on a car
