These Altmount Kits by Balmar offer the opportunity to install a larger alternator than would otherwise be possible. This one is the 48-NSP-4.6 and is for the Nanni N4.6 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 42.3" circumference K6 belt so when selecting an alternator you need one with a K6 pulley.


Read my BLOG POST about installing one of these kits.

Installation notes are on the blog post

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



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.
