How Our Team Keeps Your Crusher within OEM Spec

When it comes to crusher rebuilds, close enough doesn’t cut it.

At Marion Machine, we are proud to be a Metso Authorized Repair Facility.  This means we rebuild crushers to original equipment manufacturer (OEM) specifications—or better. That means your equipment is restored to precise tolerances, factory geometry, and optimal performance. Why does this matter? Because crushers that run out of spec cause costly downtime, reduced output, and premature wear.

Here’s how our team ensures your rebuild hits the mark, every time.

OEM Drawings and Specifications: Our Blueprint for Precision

Every rebuild at Marion starts with OEM blueprints and engineering specifications. Whether it’s a Metso HP,  or Symons 7’, we reference original dimensions, fits, and materials throughout the process.

This ensures:

• Proper bearing fits

• Correct shaft alignments

• Optimized wear part contact

• Structural integrity of critical components

We don’t guess. We measure, align, machine, and verify, by the book.

In-House Machining for Total Control

We operate one of the largest crusher-capable machine shops in North America. With in-house lathes, mills, and vertical boring mills, we restore major components like main frames, bowls, and heads to exact tolerances.

This lets us:

• Control the quality of every cut

• Minimize lead times

• Eliminate third-party guesswork

• Maintain consistency from job to job

Our 150-ton crane capacity and high capacity facilities mean no crusher is too big to bring back to spec.

Precision Measurement = Verified Accuracy

Our machinists and quality control team use a wide range of tools to inspect every component before and after machining:

• Micrometers

• Dial bore gauges

• Ultrasonic thickness testing

• Runout and alignment checks

• 3D measurement tools (where applicable)

Every measurement is logged and compared against OEM standards, ensuring the finished component isn’t just close—it’s right.

Assembly with Expert Hands

Bringing a rebuilt crusher back together is a process that demands expertise and attention to detail. Our team aligns shafts, installs bearings, and reassembles critical parts using factory procedures and torque specs.

Each assembly is tested, rotated, and inspected to confirm:

• Smooth, vibration-free operation

• Proper clearances and fastener torque

• Safe startup and long-term reliability

When the machine leaves our shop, it’s ready to go to work!

Built to Last. Built the Right Way.

At Marion Machine, our reputation is built on quality. We don’t take shortcuts. We don’t “get it close.” We rebuild crushers to OEM spec because it means better performance, longer life, and fewer breakdowns for you.

If your equipment needs a second life—bring it to Marion.
