Description
The Volvo Penta D2 50-, D2-55A D2 60 and D2-75 Serpentine Pulley Dual alternator Upgrade Kits are very easy to install Allow approx. 8 hours the first time you do this simple installation. When purchasing any Electromaax marine alternator the pulley in this kit can be installed for you at the factory. The new serpentine crank pulley simply slips over your current 5 groove crankshaft pulley and is secured with the bolts supplied. The new serpentine water pump pulley simply replaces your original. When replacing the original O.E.M. alternator with your new Electromaax high output marine alternator, be sure to read the wiring instructions prior to installing the unit. The system comes with 2 new tensioning arms.
Helpful install hints
- When loosening the 4 water pump bolts leave the existing belt in place THEN undo the bolts. This way you can use the belt to stop the W/P pulley spinning.
- Check the threads in the existing crankshaft pulley have not rusted. We find in most cases a little grease on our bolts, clean the threads out if you carefully put them in half a turn and back. Alternatively, you can use the correct thread chase.
These popular Volvo Penta D2 Marine engines, and all other engines operate much smoother, quieter and virtually eliminate belt dust and snapping belts, with our serpentine pulley upgrade kits.
These are the Genmaax super high output alternators that fit this upgrade (the 5 grooves cannot handle the torque)
