Balmar 48-YSP-3GM-A Pulley Kit for Yanmar 3GM30

On sale $495.00 $443.00
A Serpentine pulley kit permits mounting a much larger alternator because of its 10 groove serpentine belt. This kit 48-YSP-3GM-A is for the Yanmar 3GM30
p/n: 48-YSP-3GM-A
Availability: In stock

These pulley kits by Balmar offer the opportunity to install a larger alternator than would otherwise be possible; this kit is for the Yanmar 3GM30. Alternator upgrades using a single drive belt are limited by the amount of power that can be transferred by the belt but using a multi grooved belt considerably increases the possibilities. The kits include a set of serpentine pulleys for the crankshaft, water pump pulley and alternator. This pulley kit comes with two belts so you have a spare, the alternators need to be purchased separately. If you order an alternator at the same time as the kit it will come with the appropriate pulley pre-installed.

Notice

This kit is designed for use with a Balmar alternator. If you want to use it with your stock Hitachi alternator then you also need to purchase the Hitachi Pulley 48-AM-97. This special Hitachi pulley fixes an alignment issue. It may be possible to use the kit with any alternator that has a 17mm shaft diameter, but the fit and alignment is not guaranteed.
