🛠️ Service Notes
- Confirm your ratio before ordering - this assembly covers 2.32:1 and 1.95:1 only, and one number it replaces was catalogued with a 16:30 tooth count that does not read across to either figure, so check the ratio against the drive plate
- At 31.75 kg it is a freight item needing lifting equipment and proper support during fitting
- One superseded number was a remanufactured unit, so confirm with us whether this is supplied new or on exchange
