1
Complete Disassembly and Evaluation
The gearbox is disassembled so the gearing, bearings, seals, shafts, housings, bases, and lubrication condition can be inspected.
What Our PARAMAX Repair Services Include
A PARAMAX repair begins with a detailed evaluation of the gearbox and its internal components. The final scope depends on the condition of the unit, the application, and the inspection findings.
2
Bearing and Seal Replacement
Worn bearings, seals, and related components can be replaced with genuine PARAMAX parts based on the inspection findings.
3
Gear and Shaft Inspection
Gears, shafts, splines, and other internal components are checked for wear, cracking, scoring, pitting, and related damage.
4
Nondestructive Testing
NDT inspection may be used to identify cracks or defects that are not visible during a standard visual inspection.
5
Root-Cause Investigation
Damage patterns and operating conditions are reviewed to help identify why the gearbox failed and what should be addressed before it returns to service.
6
Machining and Gear Manufacturing
In-house capabilities can support gear manufacturing, shaft work, bore work, grinding, turning, and other machining required for the repair.
7
Reassembly to Factory Specifications
The gearbox is rebuilt using the applicable PARAMAX specifications, genuine parts, and the approved repair scope.
8
Inspection Report and Recommendations
Findings can document the condition of the gearing, bearings, seals, housings, bases, and lubrication system, along with recommended repair work.
9
Field Service and Start-Up Support
Support may include on-site inspections, removal and installation assistance, alignment, field repairs, commissioning, start-up, and condition monitoring when applicable.
The Benefits of Using an OEM for PARAMAX Gearbox Repair
Original Unit Information
Our team can reference the model, ratio, configuration, and design details tied to the original gearbox.
Less Guesswork During Evaluation
Product knowledge helps distinguish actual damage from normal design features, prior modifications, or earlier repair work.
Genuine PARAMAX Parts
Replacement components are selected for the intended fit, materials, loads, and operating requirements of the unit.
Factory Tolerances and Assembly Requirements
Repairs and rebuilds can follow the specifications established for that PARAMAX model.
Engineering Support for Complex Repairs
Difficult damage, unusual wear, older units, and changing application requirements can be reviewed beyond basic parts replacement.
One Source for Repair and Future Support
Sumitomo can support the inspection, repair decision, parts, technical questions, and future service needs.
Common PARAMAX Gearbox Problems
Changes in sound, temperature, vibration, lubrication, or gearbox performance can point to internal wear or developing component damage. An inspection can help identify the cause and determine the appropriate repair path.
Excessive Noise or Vibration
Unusual sound or vibration may be related to worn bearings, damaged gearing, looseness, misalignment, imbalance, or changes in the operating load.
Oil Leaks and Lubrication Issues
Failed seals, damaged surfaces, incorrect oil levels, contamination, or lubrication-system problems can affect performance and accelerate internal wear.
Overheating
High operating temperatures may point to inadequate lubrication, excessive loading, bearing damage, cooling concerns, friction, or internal component wear.
Gear, Bearing, or Shaft Damage
Pitting, scoring, cracking, spalling, shaft wear, and bearing failure can reduce reliability and may require component repair, replacement, or a broader rebuild.
The visible symptom does not always reveal the full extent of the damage. Sumitomo can inspect the gearbox and help determine whether repair, rebuild, parts, or replacement support makes the most sense.

PARAMAX Gearbox Repair FAQs
Find answers about PARAMAX gearbox inspection, repair, rebuilding, parts, and replacement support.
Can Sumitomo repair older PARAMAX and PX gearboxes?
Yes. Sumitomo can review current and older installed PARAMAX and PX gearboxes through its
industrial gearbox repair services
.
A nameplate photo, drawing, model number, service record, or inspection can help identify the unit and available repair, parts, rebuild, or replacement options.
What information is needed for a PARAMAX gearbox repair quote?
Include the gearbox model or nameplate, application details, operating symptoms, photos, and any available service history. Information about noise, vibration, temperature, leakage, loading, and downtime can also help the team review the repair request. Sumitomo’s
gearbox inspection and maintenance services
can help document component condition and the recommended repair scope.
Can a PARAMAX gearbox be repaired on-site?
Depending on the gearbox, location, and work required, inspection or service support may be available on-site. Repairs requiring full disassembly, machining, component manufacturing, rebuilding, or testing may need to be completed at a Sumitomo repair facility.
When should a PARAMAX gearbox be rebuilt instead of repaired?
A rebuild may be appropriate when several internal components are worn or damaged but the housing and overall configuration can remain in service. The final recommendation depends on the inspection findings, available parts, repair scope, operating requirements, cost, and timing.
Does Sumitomo provide PARAMAX gearbox parts?
Yes. Sumitomo can review genuine replacement parts, repaired components, custom-manufactured components, and other available options based on the PARAMAX model and repair scope. Our
genuine replacement parts support
can help identify the appropriate components for the unit.
When should a PARAMAX gearbox be replaced?
Replacement may make more sense when damage is extensive, repair costs are high, parts are unavailable, operating requirements have changed, or the repair timeline does not meet production needs. For current product information, review the
