The David Brown Specialist in the Midwest
IMR rebuilds David Brown industrial gear drives — including legacy Radicon units and current Santasalo product lines. In-house gear cutting for obsolete parts.
David Brown gear drives have a long history in heavy industry, particularly in steel mills, mining, and cement plants. Many David Brown units are no longer in production, making in-house gear cutting capability essential. IMR manufactures replacement gears to original specifications when OEM parts are unavailable.
David Brown Units We Rebuild
We work on the full range of David Brown equipment — from legacy units to current production models.
Our David Brown Rebuild Process
Every David Brown rebuild follows a documented process — from teardown through load test. No shortcuts, no guesswork.
Teardown & Inspection
Complete disassembly with photographic documentation. Every gear, bearing, shaft, seal, and housing is inspected and measured against OEM specifications.
Failure Analysis
We identify the root cause — not just the symptom. Overloading, misalignment, lubrication failure, contamination, and fatigue are all documented before rebuild begins.
Precision Machining
Worn bores are re-machined to OEM tolerances. Shafts are repaired or replaced. Housings are cleaned, inspected for cracks, and restored to spec.
Component Replacement
Worn or damaged components are replaced — gears cut in-house to AGMA standards, bearings and seals replaced with OEM-equivalent or upgraded parts.
Assembly
Rebuilt units are assembled to OEM torque specs with fresh lubricant and new seals throughout.
Load Testing
Every major rebuild is load-tested on our 500 HP test stand. Vibration, temperature, and flow are verified before shipment.
