Kits are available for a variety of Volvo engines, this kit 48-VSP-MD-B is for the Volvo MD2040 marine diesel. These Altmount Kits by Balmar offer the opportunity to install a larger alternator than would otherwise be possible. They are designed to fit select engine models, the list expands every day so if you don't see your engine listed do give us a call. Alternator upgrades using a single drive belt are limited by the amount of power that can be transferred by the belt but using a serpentine belt considerably increases the possibilities. The kits include a set of serpentine pulleys to go over the crankshaft and water pump pulley and replace the alternator pulleys and come with a matching serpentine belt. They are sold for specific engine models only. The alternators need to be purchased separately. If you order an alternator with a kit it will come with the appropriate pulley pre-installed. Installation is relatively easy. The kit comes with two 42? Circumference Serpentine Belts but purchasing an additional spare belt is recommended as these are not typical serpentine belts.

Im sorry that I do not have photos of each engine or kit, the photos shown above are generic

Installation notes are on the blog post

My blog post has installation notes for this serpentine kit.

Please mention the kit number and your engine model number in the order notes at checkout.  Thank you for your order.


This kit is designed for use with a Balmar 6 series or XT series alternator.  It may be possible to use it with another alternator that has a 17mm shaft diameter, but the fit is not guaranteed.  If you choose to go that route you are on your own.
