Diesel Engine Services

Marine Diesel Engine Specialists

Maktec engineers are from the marine or power generation industry or factory trained and know that the small adjustments made to an engine during its service or repair make it more reliable and efficient. They will ensure that your engine is correctly inspected and that parts are fitted to the makers' tolerances and specifications. On completion your engine will be ready for service after only a short running in period to bed-in the piston rings to help to reduce oil consumption and allow any new bearings fitted to re-settle.

With fuel being a major cost to companies, efficiency is now key to our customers work scopes & requirements.

We achieve this by using OEM parts and taking operational data to analyse trends and system irregularities, such as poor turbo charger performance, scavenge pressures, thermal heat balances etc.
