These Altmount Kits by Balmar offer the opportunity to install a larger alternator than would otherwise be possible. This one is the 48-NSP-3.3 and is for the Nanni NE3.30 and Nanni 4.38 marine diesel

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 belts but purchasing an additional spare belt is recommended.  This particular kit uses a 40" circumference K6 belt so when selecting an alternator you need one with a K6 pulley.

My blog post has installation notes for a different serpentine kit.

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

Notice

This kit is designed for use with a Balmar 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.
