🛠️ Service Notes

• Extra pulley 3809925 is the V-belt version with 3 grooves on the same 165 mm outer diameter and an HC50 groove; only 115 grams separate them, so order by belt type and groove profile
• The load an extra drive can take depends on belt alignment, belt type and engine type, so set the alignment carefully after fitting
• Fit a matching new belt and re-check the drive after the first few hours
• Maximum power supplied depends on the alignment of the belt, the belt type and the engine type
• The axial location of the pulley and the position of the driven equipment must suit the power being taken
