What are your options for Tier 0 and Tier 1 machines?

If “in-use” non-road emissions regulations may be in your future, or if you face other emissions requirements by way of bid specifications or green construction sites, you’re likely asking yourself what you can do with Tier 0 and Tier 1 equipment in your fleet.

There are a number of options, including repower and machine replacement.

Some emissions requirements restrict the use of lower tier machines based on their higher particulate matter (PM) and nitrogen oxide NOx emissions.

Unfortunately, installing retrofit filters can’t upgrade a Tier 0 or Tier 1 engine to the equivalent of Tier 3 or Interim Tier 4 levels. Tier 0 and Tier 1 engines have PM levels that prohibit the effective use of diesel particulate filters.

Repowering older equipment with higher tier engines may be an option, but you’ll want to consider the investment involved to purchase a new engine for an older machine. Beyond the purchase expense itself, Tier 3 engines generate more heat; this requires larger cooling systems that don’t always fit into older machines.  Rearranging components may not be worth the expense for machines with a limited remaining service life. Your equipment dealer can help determine if repowering is a viable option for you.

Another repower option worthy of investigating is replacing Tier 0 or Tier 1 engines with remanufactured Tier 3 engines.

Purchasing remanufactured engines is not only a less expensive alternative to buying new engines, but can help lower your fleet emissions average, a key measurement in complying with some emissions requirements, particularly as the economy rebounds.

Also consider renting higher-tier units from your dealer. Be sure to look for equipment dealers who carry a variety of late-model equipment with newer engines available for long- or short-term rental.

Fleets that resolve Tier 0 and 1 machine compliance issues early will have the greatest opportunity for trading or re-sale. Auction companies or other used equipment sellers may be interested in your machine.
