Pacific Energy have been dealing with Westralian Diesel for over 18 years now. During this time, they have completed in excess of 120 engine rebuilds for us both in the field and at their workshop in Perth.

We have also utilised Westralian Diesel in key maintenance roles at several of our power stations around Western Australia.
Their track record has been outstanding to date and we continue to utilise their services.

Gavin Cullen – Operations Manager, Pacific Energy

Westralian Diesel played a crucial role in helping us extend the life of our QSK19 engines on site. This resulted in reduced downtime and proved to be a great benefit to our business. We have enjoyed working with WD and their staff, and appreciate the support they have always afforded us.

Duncan Robertson – Maintenance Manager WA Operations, FMR Investments

With the unpredictable nature of mining, it is always necessary to keep your options open. Westralian Diesel are a great alternative to the OEMs and provide fast, efficient service. They were a great find for us, and we look forward to working with them moving forward.

Westralian Diesel are our preferred vendor when it comes to the sourcing of Cummins engine parts. Their personal, efficient and cost-effective service is what we enjoy most about dealing with them. They are always responsive and go the extra mile for their customers. We look forward to continuing this relationship into the future.
