⚠️ Common Signs of Failure

• Belt squeal or rapid belt wear from a worn groove
• Runout or wobble causing belt tracking problems
• Cracking at the hub or bolt holes
• Corrosion in the belt groove
• Fixings loosened by vibration

🛠️ Service Notes

• Groove profile and diameter must match the belt - this is a single HC50 groove at 120 mm outer diameter, against 165 mm for pulleys 3809925 and 3809926
• Auxiliary equipment driven off the crankshaft belt loads the crankshaft, so the axial position of the pulley and the position of the driven unit must suit the power taken
• Spacer disc 3581083 is catalogued for use when an extra pulley is mounted, so check whether it is needed
• 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
