Service exchange

Where it is critical that an engine should not be out of service for any significant length of time, our exchange schemes enable customers to keep downtime to the absolute minimum.

The principle of these schemes is simple: customers are provided with re-manufactured and guaranteed components (frequently their own) in exchange for worn components removed during the service. Components usually covered under these schemes include cylinder heads, fuel pumps, injectors, water / lube oil pumps and turbochargers. We support the Bergen K and Bergen B gas engines in our service exchange programme.
