Heavy Diesel Reconditioning, Machining and Parts Support
Heavy industry engines are pushed hard almost every day. Over time, there comes a point where retuning, fresh oil, or another round of servicing is no longer enough to restore performance or reliability.
Based in Pukekohe and backed by more than 40 years of experience, Franklin Engineering Services helps businesses understand what has gone wrong, what can be recovered, and what the best next step looks like. Franklin Engineering Services provides independent assessment, practical advice, and specialist workshop capability for heavy diesel engines across transport, earthmoving, marine, agricultural, generator, and industrial applications.
Franklin Engineering Services helps clients assess engine problems properly before committing to the wrong repair path. From independent failure assessments and performance issues through to full engine rebuilds, component machining, and hard-to-source parts, the team brings the technical experience and workshop depth needed to restore performance, extend engine life, and get critical machinery back to work with confidence.
From Parts and Component Issues to Complete Overhaul
Whether an engine is running hot, failing to hold its rating, showing signs of wear, or ready for a full overhaul, Franklin Engineering Services can help identify the cause and recommend a solution that fits the problem.
