Engine Rebuilds in Auckland,
Built to Last
Silverdale Mechanical Engineering has been rebuilding heavy vehicle engines for over 45 years. When an engine is tired, smoking, down on power or burning oil, a properly engineered rebuild can restore it to like-new performance — at a fraction of the cost of a replacement unit.
We carry out full diesel engine rebuilds and major overhauls on trucks, buses, coaches, motorhomes, excavators and plant machinery. Whether it is a top-end rebuild or a complete engine replacement, our experienced technicians work to manufacturer specifications, reassembling your engine to the tolerances that deliver power, economy and long service life.
As an MTA Assured workshop and authorised Kobelco service agent, we have the facilities, tooling and know-how to handle major engine work properly — from component inspection and replacement through to post-rebuild testing.

Does My Engine Need
a Rebuild?
Diesel engines give plenty of warning when they need major attention. Common signs include a noticeable loss of power, excessive smoke, oil consumption, unusual knocking or rattling, hard starting, or a cooling system that keeps overheating. If you are seeing any of these and are unsure whether a repair or a rebuild is the right call, our mechanics can assess the engine and give you straight, honest advice.
We work on all engine sizes and configurations — from the six-cylinder diesels found in NZ trucks and buses to the heavy plant engines fitted to excavators and machinery. Our rebuild process is methodical: strip, inspect and measure, replace what is worn, reassemble to specification, and test before the engine goes back to work.
Keeping your original engine running with a quality rebuild can be a far better investment than replacing the vehicle — especially when the rest of the vehicle and its driveline are still in good condition.
