The first Indonesian truck rebuild is part of a first batch of five Cat 789s from Thiess' Indonesian operations, which arrived on the island in October.

Thiess group executive assets, technical services and technology Ramesh Liyanage said the rebuild centre team was to be congratulated for safe and efficient project delivery.

"Our Thiess rebuild centre team is a great example of our longstanding expertise in asset management and fleet maintenance," he said.

"This rebuild facility demonstrates how Thiess can leverage its global expertise and come together to solve complex problems [and] it's the next step up in the evolution of our capabilities and service offerings."

Thiess Batam engineering general manager Daryl Albury said the usage clock on the truck was successfully reset to zero hours, which extended its service life by another 40,000 to 60,000 hours.

He said there were another four 789s stripped back and ready to go through a complete overhaul, which included a full refurbishment of the chassis and all electrical systems.

"Once they are completed, they will be shipped across to Thiess' Australian operations to meet the growing demand for fleet," Albury said.

"We look forward to this being the first truck of many over the coming years with a plan to rebuild up to 160 Thiess and third-party trucks per annum."
