The Falk Specialist in the Midwest

Industrial Machine Rebuilders has been rebuilding Falk gear drives since 1974. Every drive type, every size — torn down, inspected, machined, and load-tested in our 40,000 sq ft shop in Wood Dale, IL.

Falk gear drives are built to last — but when they fail, they need a shop that understands the engineering behind them. IMR has rebuilt hundreds of Falk units across every major product line. We stock common Falk bearings and seals, and we cut replacement gears in-house when OEM parts aren't available.

Our Falk Rebuild Process

Every Falk rebuild follows a documented process — from teardown through load test. No shortcuts, no guesswork.

01

Teardown & Inspection

Complete disassembly with photographic documentation. Every gear, bearing, shaft, seal, and housing is inspected and measured against OEM specifications.

02

Failure Analysis

We identify the root cause — not just the symptom. Overloading, misalignment, lubrication failure, contamination, and fatigue are all documented before rebuild begins.

03

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.

04

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.

05

Assembly

Rebuilt units are assembled to OEM torque specs with fresh lubricant and new seals throughout.

06

Load Testing

Every major rebuild is load-tested on our 500 HP test stand. Vibration, temperature, and flow are verified before shipment.
