⚙️ Key Features

• Alternator, Charging, Electric Motor and Electric Drives group part
• 0.249 kg
• Listed for 29 D series applications
• Supersedes 21242526
• Groove condition determines belt life and grip

🔌 Function

Transmits drive between the belt and the shaft it is mounted on, its groove profile setting how well the belt grips.

⚠️ Common Signs of Failure

• Belt squeal on start-up or under load
• Belt dust, black rubber powder or shiny glazing around the pulley
• Grooves worn, polished, chipped or corroded
• Belt running off line, fraying at one edge, or throwing itself off
• Wobble or run-out visible as the pulley turns

🛠️ Service Notes

• Renew the belt with the pulley - a new belt on worn grooves will not last, and an old belt will spoil a new pulley
• Check the pulley runs true and that the other pulleys in the run line up, since misalignment is what destroys both
• Set the belt tension to the figure the workshop procedure gives and re-check it after the first hours of running
