“Bolshy” – CATERPILLAR D9T  

The D9T has a C18 engine with Advanced Combustion Emissions Reduction Technology and Air-to-Air After Cooler producing 410 flywheel horsepower. It comes standard with 24-inch (61-cm) shoes, torque converter, differential steering, and a three speeds forward, three reverse power shift transmission.  The D9T was manufactured in the USA.

This particular machine was purchased by Goodman’s in March 2016 and was previously working in New Caledonia in a nickel mining project.  She came to us with approximately 8000hrs on the clock and needed some care and attention.

Our combined workshops carried out the rebuild and refurbish.  All completed in-house, bringing Bolshy, as we now call her, back to original condition.  She now looks fab and is working hard in the field.
