Cat 140G 12G/120G/130G/ Pump w/o Cooling — Part #8J0498

Key symptoms include reduced digging or lifting force, slow implement cycle times, excessive hydraulic fluid temperature, abnormal pump noise such as whining or knocking, and metal contamination in the hydraulic fluid. Early diagnosis prevents damage to downstream hydraulic components.

Drain and replace hydraulic fluid and filters to eliminate contamination from the failed unit. Inspect the drive coupling and mounting flange for wear. Pre-fill the replacement unit with clean hydraulic fluid before startup to prevent dry-start damage and ensure long service life.

ADH fully disassembles each unit, replaces all wear components — seals, bearings, pistons, valve plates — with new OEM-specification parts, then reassembles and pressure-tests the unit on a hydraulic bench. The result is a 12g/120g/130g/ pump w/o cooling that performs like new, backed by a warranty.

ADH offers a 1-year warranty covering parts and labour on all remanufactured hydraulic pumps and motors. Warranty support is handled directly by ADH's technical team, with fast response to minimize your equipment downtime.

Order your remanufactured unit and return your old core to ADH — the exchange reduces your net cost. Over 95% of in-stock units ship within 24h. Delivery across Canada and the United States. Return of the old unit in rebuildable condition is mandatory.
