 Engine Rebuilds

Teterin specialises in rebuilding diesel engines (Cat, MTU and other well-known brands) for mining, marine and power generation applications. Gas engines (Jenbacher, MWM and other brands) used for power generation are rebuilt at Teterin and commissioned on-site in conjunction with Teterin’s Joint Venture company Cirrus Power Systems (link to CPS web site).

Explosion Protected Diesel Engine Rebuilds – EX DES.

Teterin is the industry leader and industry standard for the overhaul and rebuilding of EX DES engines used in underground mining with gaseous atmospheres.



Engine Component Reconditioning

For those customers who choose to dismantle and rebuild engines in-house, Teterin provide a high-quality and speedy turnaround of  reconditioned engine components. Engine components can be engine crank case (block), crankshaft, connecting rods (conrods), cylinder heads and any number and type of auxiliary components (radiator fans, pump housings, gears, manifolds).



Service Exchange

We understand our customers in mining and power generation have production and service commitments which need to be up-held. Teterin’s engine component service exchange program is tailored to provide critical engine components such as specialised crankshafts (CAT 3516HD) and engine blocks (CAT Ex DES, CAT, MTU - long and short) available to minimise delays to our customers production.




Technical Support – Critical and Complex Engineering

As the industry leader, Teterin is frequently involved with customers who want greater reliability with lower through-life costs from their engines.  Teterin  works collaboratively with the customer to design technical solutions which extend the life of engine components and improve the reliability of engines performing critical and complex operations. On other occasions, Teterin has been tasked to undertake Research and Development and feasibility trials on first-in-country reconditioning of complex and critical sub-sea engine blocks and associated components.



Field Service & Insitu Machining

The field service group are available to perform routine maintenance to diesel engines in the field and also break-down maintenance where time is of the essence. The field service group are some of our most knowledgeable and skilled employees. They have all the necessary site safety inductions, insurances and operate from fully equipped service vehicles many of which are 4WD. The field service group are available on-call at any time and operate through-out NSW, Queensland and nationally according to the demand for specialised diesel engine field service.

Insitu machining is also a key competency that Teterin Engineering provides. Teterin Engineering’s ability to offer insitu machining of large diesel and gas engine cylinder blocks enable In-Frame engine rebuilds to be done to a much higher standard, reducing operational risk moving forward by getting the engine back into service quicker with greater reliability.
