Precision ‘Zero Hour’ Rebuilds

Our team includes some of the most experienced and highly skilled engineers in this field globally, and our equipment is world-class.

We perform diesel and gas engine rebuilds for the Mining, Rail and Gas Industries in accordance with engine manufacturer specifications and customer requirements, using genuine or aftermarket spare parts as specified.

Extensive Workshop Capacity

Teterin’s engineering facility includes large dedicated rebuilding bays and is equipped to recondition engine blocks up to 6,000mm, crankshafts up to 4,600mm, and cylinder heads up to 350kgs, with rapid turnaround and proven precision and quality.

We rebuild large diesel and gas engines and smaller ExDES (Explosion Protected Diesel Engine Systems), including:

  • Large Diesel & Gas Engines: Jenbacher Type 3, 4 and 6; MWM 2020, 2016 series; Deutz TGC620, TBD620; MTU; MAN.
  • Small ExDES Engines: Cat 3126, 3306; MWM 4.10 TAC; Perkins 1006, 1104.

Rebuilt gas engines can be commissioned on-site in conjunction with Cirrus Power Systems, a Teterin joint venture with Germany’s August Storm GmbH & Co. KG.

Industry Standard for ExDES

Teterin is NATA-accredited for work on ExDES engines, common to the Underground Mining Industry. We have long been a recognised ExDES facility, setting the industry standard for ExDES overhauls and rebuilds.

Rebuilt ExDES engines are dynamometer tested and gas emissions tested in the Teterin Engine Test Cell prior to dispatch.

Proven Reliability, Faster Turnaround

Our Quality Management System is certified to ISO 9001:2015 ensure a consistently precise standard of work, which translates to greater engine reliability, longer service intervals, lower through-life operating costs and better value for money.

Recent significant investment in programmable CNC crankshaft grinding and valve seat machining centres has also enhanced our ability to deliver repeatable precision and faster turnaround time. For instance, our CNC crankshaft grinder – the only one of its kind in Australia – allows us to quickly grind every journal to very high levels of repeatable accuracy. This investment in our machining capability, together with our industry-leading ERP System and integrated Quality Management System, enables us to perform at world-class standards, to minimise your downtime and maximise your profitability.
