But while the California Air Resources Board has backed off somewhat in its draconian off-highway cleanup rules, Sukut had already embarked on an aggressive repower program. Sukut Equipment is no stranger to repowers, working in one of the most environmentally conscious states in the nation.
“The $350,000 ticket is a very cost-effective way of extending the useful life of the machine, while making it acceptable to bids for environmentally sensitive sites,” said Ortiz. Given the repower, and some other updating to the Cat D11 dozer, the expense is a fraction of the new cost. The repower puts a modern Cat C27 into the engine compartment of the earlier dozer, adding another two decades of life to a tractor that has already worked 20 years. Ortiz has recently added a new D11T to the fleet and says the price came out at $2.2 million. Since 2008, the biggest Cat is the D11T, weighing some 230,000 pounds. It superseded the D10 as the biggest crawler dozer in the Cat product range. The Cat D11N dozer was first introduced in 1986, powered by a 3508 mechanical Cat at 770 horsepower.
Sukut Equipment’s Cat D11 dozer was an earlier version of the biggest Caterpillar bulldozer. Sukut Construction is one of California’s major contractors. Sukut Equipment is a rental company, with more than 250 big machines, that supplies the equipment needs of Sukut Construction, among other clients. By doing so, the California-based construction company Sukut Construction is able to meet bid requirements in contracts that specify minimum Tier II emissions level on job sites, said Mike Ortiz, equipment president of Sukut Equipment. The task was to bring the older Cat D11 dozer up from an earlier spec with its unregulated Cat 3508 engine to Tier II emissions. The first repower of a Caterpillar D11N has been completed in a joint effort between Southern California’s Johnson Caterpillar and the Cat repower team.
