| Symptom | Likely Cause | Fix | |---------|--------------|-----| | No vibration | Failed vibration solenoid or pump drive coupling | Replace coupling; flush hydraulic circuit | | Hydraulic overheating | Blocked cooler core or low fan speed | Clean core with compressed air; check fan belt tension | | Uneven compaction (streaks) | Worn or missing scraper bars | Replace scrapers and tighten to drum surface | | Error code “E181” | Low DEF quality (Tier 4 models) | Drain DEF tank, refill with certified fluid |

Always update the machine’s software via a Cat dealer. Older software versions (before 2020) had a glitch that caused intermittent vibration lockouts. 10. The Future: Is the CS 907 Still Relevant? With Caterpillar pushing toward electric and autonomous machines, is the diesel-powered CS 907 becoming obsolete? Not yet. Electric compactors currently lack the runtime and power density needed for 20-ton soil compaction. The CS 907 remains the gold standard for heavy soil work, especially in remote locations without charging infrastructure. | Symptom | Likely Cause | Fix |
