If the customer wants to use his own radiator package or other components then we have to sign off on those. A lot more testing may be involved." Engine distributors typically have kits available to hook up the most common engine repowers, and for these, the appraisals and engineer- ing have already been done. But if the repower you're considering is something they've not yet encoun- tered, the extra engineering and testing required to ensure that it works may add to your cost. Bigger is better As a general rule, bigger machines are better candidates for repowers than compact units, says Chrusciel. "When you get to the point where you need to replace the engine on a compact machine, that machine is usually wrung out. We find many times it's just better to go out and get a new machine." "Scrapers have been popular for repowers, as they have large en- gine bays, generate large numbers of hours per year and are durable platforms," says Rochford. "The same applies for motor graders, off-highway trucks, track-type trac- tors and wheel loaders." On these big frame machines, the repower cost is normally less than 15 per- cent of the cost of a new replace- ment machine, he says. The decision to repower or not should also take into consideration your fleet's profile and needs. "Go back and do an inventory of your machines and look at the work you're going to be doing over the next 10 years or so," says Micu. "Once you do that, you can get a pretty good idea of what machines are going to be around in that time and what you're going to need to replace. And then you're going to have to make some tough deci- sions based on that." Funding available If you want to put a Tier 3 engine in a lower tier piece of equipment or you want to retrofit equipment with more efficient exhaust after- treatment devices, the government has money available to help you. There are two main federal pro- grams for diesel-powered construc- tion equipment: •The Diesel Emission Reduction Act (DERA): www.epa.gov/clean- diesel. •The Congestion Mitigation and Air Quality (CMAQ) program, which helps states with air qual- ity problems use a portion of their funds to retrofit off-road construc- tion equipment: www.fhwa.dot. gov/environment/air_quality/ cmaq/. There are also numerous state and municipal programs to help fund diesel repowers and retrofits.
