In instructions where operation numbers are included in the heading, this is a reference to the Volvo Penta Flat Rate list.

Spare parts

Spare parts for the electrical and fuel systems are subject to various national safety requirements. AB Volvo Penta Original Spare Parts fulfil these requirements. All forms of damage that result from the use of parts that are not original AB Volvo Penta spare parts for the product in question will not be covered by the guarantee from AB Volvo Penta.

Certified engines

For engines that are certified for national and regional environmental legislation, the manufacturer binds itself to meet the environmental requirements for both new engines and those already in service. The product must correspond with the example approved when the certification took place. In order for Volvo Penta as the manufacturer to be able to be responsible for engines in operation meeting the environmental requirements, the following requirements for servicing and spare parts must be met:

● ● The service intervals and maintenance procedures that AB Volvo Penta recommends must be followed.

●

● ● ● Only AB Volvo Penta Original Spare Parts intended for the certified engine configuration may be used.

● ● Servicing of injection pumps, pump settings and injectors should always be carried out by an authorized AB Volvo Penta workshop.

● ● The engine may not be rebuilt of modified in any way, except for accessories and service kits that AB Volvo Penta has developed for the engine.

● ● Changes may not be made to the exhaust pipes and intake air ducts for the engine room.

● ● ● ● Unauthorized persons may not break any seals.

IMPORTANT! When you need spare parts, use only AB Volvo Penta original parts. Using non-original parts leads to AB Volvo Penta no longer being responsible for the engine corresponding to the certified design. AB Volvo Penta will not cover any damage or costs arising from the use of non-original Volvo Penta spare parts for the product in question.
