What We do

Our multi-million dollar computer controlled replacement parts inventory exceeds 70,000 line items with warehousing facilities of over 1250 square metres. We source OEM quality replacement parts from around the world and our product quality is only surpassed by our service and knowledge.
Order fill rates exceed 85 percent with back-orders supplied within 24 hours in most cases. When it comes to service and product quality it is our belief that we have set the industry standard.

Our staff has a solid grounding in the industry and excellent resourcefulness. 

Our parts department started operating in 1984. Replacement parts sales comprise five basic products

  • Used Parts
    The process begins with a machine that is fully dismantled in our workshop. Any sub-standard parts are disposed of. All of the re-useable parts are chemically cleaned, inspected, sprayed with preservative, computer located and stored.
  • Surplus Genuine Parts
    Parts are sourced from suppliers throughout the world so we can supply those hard to get items that no-one else seems to have.
  • Reconditioned Exchange Parts
    Parts are rebuilt to standard specifications and offer real savings compared to new parts.
  • New Aftermarket Parts
    Parts are sourced from leading manufacturers in Australia, Asia, Europe and America. These parts are of OE quality and are covered by warranty. Our US manufactured engine parts warranty is two years.
  • Underground Mining Parts
    We stock a large range of Cat Underground Parts and components to suit R1700, R2900, IT28G, AD40& 45 and more.
    We are also wrecking these machines.

A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine.

I am so happy, my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents. I should be incapable of drawing a single stroke at the present moment; and yet I feel that I never was a greater artist than now.

When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary, I throw myself down among the tall grass by the trickling stream; and, as I lie close to the earth, a thousand unknown plants are noticed by me: when I hear the buzz of the little world among the stalks, and grow familiar with the countless indescribable forms of the insects and flies, then I feel the presence of the Almighty, who formed us in his own image.
