Engineered Repair – Plug Screw Feeder
Provided an engineered repair solution to damaged screw feeder equipment critical to paper packaging manufacturing. Read about our process in meeting all technical requirements and rush schedule.
Case Studies
Precision Machining – Propeller blade
Our team precision machined the propeller blade for a container ship transporting critical supplies to Alaska. We met all technical specifications and delivered the part within the drydock schedule.
Equipment Modification – Feed cylinder
Precision machined this cylinder equipment to meet OEM specifications. Accuracy of machining and conformance to technical specifications and timeline were critical to the equipment modification.
Thermal Spray Repair – Wicket Gates
Thermal spray repair of large wicket gates for a hydroelectric power plant. Wicket gate stem fits were restored back to OEM specifications and saved on long-term maintenance cost.
Shaft & Tapered Sleeve Manufacturing
Manufactured a critical shaft and test sleeve for a science research facility serving federal and commercial customers. Certifications and adherence to specified dimensions, surface finishes, and tolerances were required.
New Press Roll – Design & Manufacture
Manufactured and designed new roll and new shafts for upgraded performance.. No OEM drawing was available so the team reverse engineered the new roll and journals.
Thermal Spray Repair – Screw Press
Thermal spray repair on a large industrial screw press with multiple bearing and seal fits that were out of OEM specifications.
Wind Turbine Main Shaft & Components Repair
The main bearing failed catastrophically and damaged several components including the bearing housing cover, retaining nut, and sealing rings. The bearing housing itself was also damaged and new replacement was not available. With a critical timeline, our team completed all repairs and replacements within the required 10 days.
Gas Turbine – Machining & Refurbishing
Precision machining of gas turbine components for a pollution control modification project at an Oregon power plant. The turbine case, combustion wrapper, and compressor discharge case were machined to precise specifications and completed within the shutdown timeline.
Ship Shaft – Comprehensive Shaft Repair
Comprehensive shaft repair for a global ship owner and operator. The propulsion shaft had three liners that were severely worn out and each one had a different interference fit that required precision machining. With stringent specifications and critical timeline, an engineering approach was needed from start to finish.
Forming Roll – Machining & Shaft Manufacturing
Comprehensive engineered repair for a forming roll critical to the manufacturing of a fiber cement product. Western Machine Works provided precision machining, shaft manufacturing and installation, grinding and balancing, non-destructive testing, and custom tooling. The result: customer saved capital dollars and time by refurbishing the roll instead of full replacement.
Roller Shaft – Engineered Repair & Manufacturing
Western Machine Works manufactured a replacement shaft for a plate rolling drive roll based on the engineering team’s interference shaft fit design. The damaged drive roll was bored out to accommodate the new manufactured shaft.

Loading Arms – Engineered Repair & Machining
Western Machine Works repaired the breast roll loading arms in 4 days, saving critical time and capital dollars for a global tissue manufacturer.
Hydro Turbine Guide Bearings – Machining
Western Machine Works maintained the surface integrity of the lignum vitae wooden staves while achieving the required ID, TIR, and RA finish
Rotor Shaft – Machining & Manufacturing
The damage to the bearing fit on this rotor shaft was beyond repair. Used for a chemical compressor, the equipment’s concentricity was critical and fast turnaround was required.
Hydro Turbine Bushings Manufacturing
The slusher runner housing was extensively damaged from bearing failure. Our team manufactured this critical equipment for a paper mill customer without manufacturing prints and drawings in just 5 days.
Slusher Runner Housing Manufacturing
The slusher runner housing was extensively damaged from bearing failure. Our team manufactured this critical equipment for a paper mill customer without manufacturing prints and drawings in just 5 days.
Hydro component: Gate Shift Ring Fabrication
A hydropower utility customer had a severely cracked gate shift ring. After considering the time line and cost parameters, Western Machine Works’ fabrication solution proved to be the best option.
Hydro Turbine Thrust Bearing
A hydropower provider contacted Western Machine Works to machine their newly fabricated hydro turbine thrust bearing to precise tolerance and RMS finish. The fabrication shop they initially contracted failed to achieve the specifications, causing damage to the bearings.
Gearbox Repair and Rebuild
A wood processing customer needed this silo gearbox repaired and rebuilt, due to its history of chronic failure. No manufacturing prints were available, so our team reverse engineered the parts.
Motor Armature New Shaft Manufacture
The shaft of this motor armature was damaged beyond repair. The WMW team created the manufacturing drawing and manufactured the new shaft and machined the armature bore to 100% concentricity.
Press Roll Bearing Fit Repair
Customer called over the weekend needing emergency repair of a broken down press roll bearing fit. With WMW’s specialized twin arc metallizing process, the repair was completed and bearing fits restored within 3 days.
Propulsion Shaft Refurbishment
The liners for this propulsion shaft aboard the Kilo Moana, a research vessel operated by the University of Hawaii were severely damaged. Western Machine Works manufactured the new liners and the shaft was certified refurbished by ABS (American Bureau of Shipping).
Hydro Bearing Tub & High Hat Fabrication
These hydro components, namely the bearing tub and high hat were damaged and causing seal failure. Western Machine Works reverse engineered a new high hat and repaired the bearing tub.
