Connecting Rod 8980139624 for John Deere 75C 80C – Scheduled Maintenance
Connecting Rod 8980139624 for Isuzu 4JG1 / 4JG2 engines, forged steel construction — compatible with John Deere 75C and 80C excavators. Mid-to-late lifecycle replacement: inspect during major service intervals for knocking or bearing scoring; single-rod or full-set swap depending on wear state across cylinders. Supports planned overhauls rather than unplanned teardowns, aligning rod renewal with scheduled fleet downtime. Replacement interval guidance included with shipment to support long-term maintenance scheduling for aging 75C / 80C fleets.
