290-6527 is identified by Cat as a motor group used on 966H and 972H wheel loaders. Cat marks the original reference as discontinued and directs buyers to confirm replacement options through the equipment record. The official page publishes alloy-aluminum construction but no voltage, power, rotation or tooth count, so the legacy 24V and 13-tooth claims are not repeated. Send the original unit photographs and machine serial number so the currently supplied replacement can be checked before quotation.
