Helpful tip to upgrade your Perkins 4107/4108 Marine Diesel Engine.
Perkins 4108 diesel owners often need additional crankshaft pulleys to drive larger alternators or refrigeration compressors. After all, the standard Perkins 4108 alternator is usually an anemic 35 amps. We have developed an easy-to-install auxiliary crankshaft pulley for 4107 and 4108 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 are helpful. We believe tech support matters.
