402-8600191 – 24VOLT 270AMP 50DN BELT DRIVE GENERATOR

Product Description

This 50DN Alternator incorporates the latest drive end housing and front seal service kit part #10524488. The new design represents an improvement over the previous retainer, seal, gasket, and bolt assembly. The alignment service tool required previously is also eliminated. Delco has superseded all complete belt driven 50DN new service generator production to this updated design as of 2009.08.19. This new revision can replace all previous belt driven 24 volt 50DN versions that incorporated the previously used 1988307 front drive end housing.

The Delco 50DN Alternator has been around for a long time and is tried and proven in the Transit Bus and Coach industries. It has gone through many revisions and this latest is available from Elreg under part #402-8600191. This alternator has the following specifications:

• Maximum Speed: 6,500 rpm Continuous / 7,000 rpm Intermittent.
