User Insights & Reliability Notes
Reddit feedback raises caution:
> “The CAT 320D2 series and the newer model have reliability issues pretty early in its life (5,000hrs up to 10,000hrs)… broken injector pump at 8k hrs… stuck adjuster due to Cat’s grease… engine derate under 1,000 hrs.”
While these reports are dated, they highlight that owner maintenance and dealer support critically affect reliability—especially on older units.
However, many operators value Caterpillar eye‑ease-of-repair culture and system simplicity. Combined with economic engine features, these factors make D2L a practical choice in fuel‑sensitive regions.
Maintenance & Operational Tips
To get the most life from a 320 D2L, maintain oil‑cooler cleanliness, service fuel filters at recommended intervals, and watch for injector or fuel‑sensor-related derate events. Ensure pins/bushes are regularly greased and tracked alignment is monitored post bushwork. After ~20k hours, major components may shift from wear to repair cycles. Correct undercarriage tension maintains stability over the long haul.
