Balmar Serpentine kit for Volvo D2-40

[Networker]

Hi, I recently bought a FP Helia 44 catamaran and it came with the Volvo Penta D2-40 engine. I'm trying to buy new alternators and new serpentine kits for it from Balmar. Helia's were sold with either the d2-40 or d2-55.

The Balmar website lists just a few engine types for their serpentine kit, one of which is the D2-55.

Does anyone know if the d2-40 and d2-55 are the same physical size, and as such, a serpentine kit for the d2-55 would work on the d2-40?

Thank you in advance for any insights!

No - the D2-40, and the D2-55 are different sizes, and I wouldn't expect the serpentine kits to match.


The ‘D2' 40 & 55 are both 4 cylinder engines, of different displacements:
D2-40: 1.51 litre - 29 kW / 40 hp @ 2800-3200 RPM
D2-55: 2.2 litre - 41 kW / 55 hp @ 2700-3000 RPM

They seem to have different manuals:

The Volvo Penta D1 and D2 come with a very powerful generator [alternator] – 115 A and 12 V – fitted as standard.
In the case of the two largest models, the D2-55 and D2-75, which are often installed in large yachts, additional charging is needed. The engines are now available fitted with additional combinations of 12 V and 24 V generators as options. With a 24 V generator, it is easy to have both a 12 V and a 24 V system on board.

Very helpful! I will call Balmar Monday to see what they recommend, glad I didn’t order the d2-55 pulleys yet!
