Zenith Engineering Pty Ltd commenced business in October 1945 when brothers Tom and Terry Jennings and Jim Carroll formed a partnership. At that time it was their intention to manufacture automotive and hydraulic components during that era of post war reconstruction.The business they created continues to this day and is presently owned and managed by the families of the original proprietors. In 1979, the company became involved in the marketing of the very extensive range of Isuzu diesel engines. At that time, General Motors GM Components Division commenced importing the units and it was considered that Zenith could make a contribution in the area of application engineering. Zenith has applied the engines to a wide variety of Industrial and Marine applications for a period of 43 years. Today, Isuzu are the largest producer of diesel engines in the world.In addition to this, through the period from 1945 to 1979, Zenith Engineering had developed a close association with many other industries including agricultural and mining. By collaborating with end users within the mining industry Zenith Engineering designed and developed a high pressure grout pump which is used in underground mines in the application of cable bolting.Today, Zenith Engineering Pty Ltd conducts a substantial engineering business and components design facility at The Yard Brisbane in the suburb of Hemmant.
