Engine Component Rebuild


Cat engines are built for multiple lifecycles. A WesTrac engine rebuild ensures that you are getting maximum value for your investment.

How much can you save?

On average it is 2.5 times more expensive to repair after failure than before failure. As an example of the savings you'll make by investing in an engine component rebuild, the costs involved in a level 1 rebearing/reseal start from only 25% of new.

We classify engine parts into 3 levels

It pays to ensure regular replacement and maintenance of:

A. Fast wear parts

Fastest wearing, non-reusable, should be replaced at regular overhauls. E.g. piston rings, bush and valve guide.

B. Slow wear parts

Slower wearing, can be reused with discretion and regular maintenance. E.g. pistons, cylinders and camshafts.

C. Very slow wear parts

With regular before failure repairs, they should last the life of the machine, so not usually replaced during overhauls. E.g. cylinder block, cylinder head and crankshaft.

Classification of parts for engine rebuilds

How to maintain engine performance and lower repair costs over time

  • Promptly replace Fast Wear and Slow Wear parts to avoid damage of Very Slow Wear parts.
  • Use Genuine Cat engine oil and filters.
  • Perform scheduled oil sampling (SOS™) for early detection and elimination of potential failures.
  • Select Caterpillar-compliant pollution control workshops to perform engine repairs.

Choose your level of repair

Every engine rebuild starts with four key questions:

  1. Ownership - How long do you plan to own the machine?
  2. Utilisation - How much/often do you plan on using the machine?
  3. Affordability -What are your price expectations?
  4. Turnaround - How quickly does your machine need to get back to work?

Based on your answers to these four questions, we would recommend one of three levels of repair as outlined in the table below.
