Helpful tip to upgrade your Perkins 4107/108 Marine Diesel Engine.

Perkins 4108 diesel owners often need additional crankshaft pulleys to drive larger alternators or a refrigeration compressor. After all, the standard Perkins 4108 alternator is usually an anemic 35 amps. We have developed an easy-to-install auxiliary crankshaft pulley for 107 and 108 Perkins diesels. With this innovation, the Perkins 4108 diesel owner can run a larger double sheave alternator. See Foley Tech Tip #28, Selecting and Installing A High Output Alternator, for a discussion of alternators and their installation.
We hope that the Tech Tip have been helpful.  We believe tech support matters.
