Drive belts. Inspection/adjustment
Inspection and any adjustment should be done after
operation, when the belts are hot.
Loosen the screws (A) before tensioning the alterna-
tor belts. It should be possible to press the belts down
about 10 mm (3/16 ") between the pulleys. Worn belts
which operate in pairs should be changed together.
On TD420VE, TAD420VE and TAD620VE, the fan
belts have an automatic belt tensioner and do not
need to be adjusted.
TD520GE, TAD520GE, TAD520VE, TAD620VE,
TD720GE, TAD720GE, TAD720VE, TAD721GE,
TAD721VE, TAD722GE and TAD722VE have me-
chanical belt tensioners.
Always check the condition of the drive belts. Change
