Questions about this item

How do I install the 49 V-BELT A47 4L490 on my EXV155-B, and what step is most often missed?

Route the belt around the motor and fan pulleys, then tension it so there is roughly 15 mm deflection at mid-span; the step most people skip is re-checking alignment after the first hour of operation.

What maintenance or replacement will the G2490 belt need later?

Inspect the belt every 155 operating hours for cracks, glazing or stretch; replace it once deflection exceeds the 15 mm guideline or at the start of each cooling season.

What limit appears first when the EXV155-B runs continuously under load?

The belt’s heat resistance is the first limit; sustained high temperatures accelerate glazing and stretch, so monitor tension closely during extended runs.
