| Worn chains and sprockets may be working improperly long before they actually break. |
| The aforegoing recommendation applies both to the driver sprocket and all idler sprockets in the loaded strand range. |
| And there will also be other jobs to do from time to time, like changing brake pads, fitting a new chain, changing sprockets to alter your gearing. |
| Hardened metal shims on the nose sprocket protect bearings and provide longer service life than regular nose sprockets. |
| Moreover, the driver sprockets should have a minimum of 25 to 32 teeth so as to avoid the polygon effect and not to overtax the chain rollers. |
| The undercarriage supports the house structure and includes the tracks, drive sprockets, rollers, and idlers. |
