Product details

Our factory-rebuilt alternators have a 1 year warranty and offer optimum performance at an affordable price. All units have a built-in controller, but can be supplied with a "Sterling" high-performance controller on request.

These alternators fit a wide variety of engines. Other special types of alternators are available upon request.

Which criteria should be considered when selecting a replacement alternator?
1. Robust construction

Marine alternators are usually operated under high loads. To achieve a long service life, they should be equipped with high-temperature grease, large cooling vents, large fans, high strength bearings and high-current diodes.

2. High performance
The alternator output should be between 25% - 40% of your total battery capacity.

3. Structural shape
Most replacement alternators are available in 4 different designs. The structural shape is determined by the width (B), number and spacing (C) of the bottom attachment points (eyes). This can be compensated for with spacers.

4. Belt pulleys
Heavy-duty alternators require different belt widths according to their power. Up to 70A, a 3/8" (10mm) belt is required and up to 100A, a 1/2" (13mm) belt is required. For units above 100A, a double belt is recommended.

Note: Item 83461 is double insulated (floating ground).

The alternator was installed in a Volvo MD21B, there were no adjustments to the housing, etc. necessary, only on the tensioner must be 2 U discs interposed so that the V-belt was aligned, or the LM was not distorted.
