Diesel & Petrol Engine Rebuilding

4WD Systems has been repairing & reconditioning 4WD Diesel & Petrol Engines for 18 years. Our process is to fully disassemble, comprehensively inspect all components and replace or recondition any part our qualified technician deems too worn for reuse.
We ship engines all over Australia, many to work site environments. Most of our technicians have worked in the petroleum and mineral exploration industries, hence understand the cost of interruption due to part failure.

Following is a list of pertinent points relating to our engine rebuilds:
