EPA defines an “Engine” as an assembled Block and Crank.
Everything from a Short-Block Assembly to a Complete Engine has the same EPA Engine rules.
A bare Block and a bare Crank are unrestricted parts, but anyone that assembles a new Block and new Crank is an Engine Manufacturer with the applicable EPA responsibilities.
New Certified Engines:
Typically available through Industrial Engines
- Certified compliant with the emissions rules in place when they are/were imported (now Tier 4)
- “New Old Stock” that was Certified when imported prior to 2013 is still Certified for new replacement use up to the year they were certified to.
- Yanmar’s Repurpose program originally used New Old Stock Certified engines. All of the popular specs have been consumed. Mastry Engine Center still has a few less popular engines specs available.
New Replacement-Only (NRO) Engines:
- Complete NRO engines have the same availability as above. Typically available through Industrial Engines
- NRO Short-Block Engines are available through REMAN (purchased through Parts, administrated REMAN)
- NRO Engines built up from NRO SB Engines (to HBC, LB, 3/4, or Complete) are available through REMAN
- Repurpose NRO Engines of any completeness level are available through REMAN
- All NRO Engines (SB to Complete from any department) are under same EPA NRO rules & must be tracked.
- Tracking requirement includes Engine Models and Serial Numbers of all engines (import, REMAN/Repurpose, & recovered core)
- Understandably REMAN engines cannot be exported or the program would slowly shrink.
- Repurpose NRO engines can be exported but will be subject to a core charge.
- NRO engines can be exported and/or relabeled with appropriate documentation.
