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.
