Field, Shop, and Maintenance Support

Not every repair can wait, and not every repair belongs in the field. OnSite Diesel provides both mobile field service and full-service shop repairs to support construction equipment when and where it makes sense.

Mobile Field Service

Our field service trucks support on-site diagnostics, diesel engine repairs, hydraulic service, component replacement, welding, and line boring to help reduce downtime and avoid unnecessary transport.

Full-Service Shop Repairs

For major repairs, rebuilds, fabrication, machining, and complex component work, our shop provides the tooling and controlled environment needed to restore equipment performance.

Hydraulic System Repair

We troubleshoot and repair hydraulic systems, including hoses, cylinders, pumps, valves, fittings, seals, and related components that keep construction equipment working.

Diesel Engine Repair

Welding and precision line boring are core capabilities at OnSite Diesel. We perform structural welding and bore repair to restore worn or damaged components, helping customers avoid costly replacements and extend equipment life.

Welding & Line Boring

We perform welding and precision line boring to restore worn or damaged booms, arms, buckets, blades, linkage points, pins, bushings, and structural components.

Preventative Maintenance

Routine maintenance helps contractors reduce unexpected failures and keep equipment ready for the next phase of the job. We support inspections, fluid and filter service, wear-part checks, and fleet maintenance.

Parts Support

We can help source OEM, aftermarket, used, and salvage parts for construction equipment, including hydraulic components, drivetrain parts, undercarriage parts, buckets, wear parts, pins, bushings, and cooling components.
