When should I consider a rebuild?

Cat mining machines are built to last, and rebuilt for multiple lifecycles.

Although the machines operate in harsh mine conditions for over 6,000 hours per year, maintenance and condition monitoring prolongs the productive life of machines.

WesTrac supports our customers with parts and services to keep their assets in good condition and reduce downtime.

Below is a rough guide on when components or machines should be considered:

2 to 4 Years: Hydraulic cylinder repairs and preventative maintenance on hoses
4 to 6 Years: Used components can be sent to WesTrac for rebuilding (repaired and reused multiple times)
10 Years: Prepare for next machine life, Cat Certified Rebuild, Full Cycle Rebuild, Powertrain Rebuild, Machine Component Rebuild
13 to 15 Years: Option for Full Machine Rebuild

How long will my asset be down?

How does a rebuild help with my ESG goals?

By investing in a rebuild instead of buying new you’ll be avoiding wasted materials and promoting a circular resource economy – which is something that can become a critical part of your sustainability strategy; just like it’s part of ours. We use Cat Reman parts, which reduces the need for raw materials, meaning mining companies can lower their environmental footprint.
