With more and more electronics being used on boats, the demand for more 12v DC amperage is increasing.
If you are using a high output alternator on a Perkins 4.236. 4.107. 4.108.or Westerbeke 40 with a standard belt, you already know the problem.
Belt dust due to slippage and the constant worry of re-tensioning the belt. The danger of a slipping belt can result in reduced life and could fail leaving the engine without the function of the fresh water circulating pump.
The Trans Atlantic Diesels Serpentine Pulley Kit can solve your problem. Select your engine below to get started.
This kit facilitates installation of a Balmar AT-SF-200-K8 alternator to fit a standard Cummins alternator bracket (Cummins part number 3923387 2” foot).
If your engine has a different alternator bracket, you will need the following Cummins parts: (3923387 Alternator bracket) (2908226 Bolt) and (3910715 Mounting Spacer).
These parts available through TAD.
You cannot fit the Balmar AT-SF-200-K8 alternator without a modification kit such as we are offering.
