Industrial Diesel Manufacturing & Remanufacturing in Decatur, TX


At our Decatur, Texas facility, Industrial Diesel manufactures and remanufactures industrial diesel engines to factory-spec standards. Every engine that leaves our shop goes through a controlled process of teardown, precision machining, OEM-spec component replacement, and full testing — built to perform like new, not just patched to run.


Our Manufacturing & Remanufacturing Process

Teardown & Inspection — Every engine is fully disassembled and inspected component by component to identify wear, damage, or out-of-spec parts.

Precision Machining — Blocks, heads, and rotating assemblies are machined in-house to factory tolerances.

OEM-Spec Component Replacement — Worn parts are replaced with OEM or OEM-equivalent components — no shortcuts on critical wear items.

Assembly & Testing — Engines are rebuilt to spec and run through testing before they're approved to ship.

Quality Control & Certification — Each unit is signed off against our internal quality checklist before it leaves the facility.

Manufacturing vs. Rebuilding — What's the Difference?

A rebuild restores your specific engine to reliable working condition. Our manufacturing and remanufacturing process goes further — engines are brought back to factory-spec tolerances using OEM-standard components, so performance and longevity match a new unit rather than a repaired one.
