Tier 3 Refurbishment & Repower Program

Extending the Life of Your Industrial Assets

Federal emissions regulations require industrial non-road diesel engines to meet increasingly stringent standards, such as Tier 3. If your valuable equipment relies on older, pre-Tier 3 engines, you face a major challenge: either retire perfectly functional machinery or find a solution to bring it into compliance.

Longley Diesel specializes in the latter. Our Tier 3 Refurbishment and Repower Program offers a cost-effective, sustainable solution to extend the service life of your industrial assets by replacing older engines with new, compliant Perkins engines.

The Repower Solution:

Compliance Without Replacement

Our program is centered on removing the older, non-compliant engine and installing a new, certified Perkins engine that meets current Tier 3 emission standards.

This strategic repower allows your existing, proven industrial chassis, pumps, drills, generators, or other non-road equipment to remain fully operational and compliant. This process saves you significant capital compared to purchasing entirely new Tier 3-compliant machinery.

What Sets Us Apart?

We model our high standards on successful industrial repower operations to ensure our clients receive maximum value, compliance, and reliability.

Compliance Focused

We exclusively utilize new Perkins engines certified to meet the specific EPA Tier 3 standards for non-road industrial equipment. This ensures that your equipment is legally compliant and ready for service in any regulated environment.

Industrial Specialization

Our expertise is strictly focused on off-highway industrial applications (e.g., drilling, power generation, construction). We do not perform emission upgrades for on-highway vehicles (like semi-trucks), as those standards (EPA and DOT) are entirely separate and require different certification programs. Our specialization ensures efficiency and regulatory accuracy for industrial fleets.

Seamless Integration

A repower is more than just swapping engines. Our technicians are experts in diesel engine mechanics and integrate the new Perkins power plant seamlessly with your existing equipment’s frame, hydraulics, and controls, ensuring original performance specifications are met or exceeded.

Cost-Effective Longevity

We provide a detailed cost analysis showing that the investment in a Tier 3 repower offers a superior financial return compared to the high capital outlay and potential lead times associated with purchasing new equipment.
