## ⚙️ 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
