Description
The Perkins 4.154 Serpentine Pulley Upgrade Kit looks complicated and large however this kit is very easy to install. Allow approx. 4hours and 30 minutes 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 (micro ‘V’) crank pulley simply slips over your current crankshaft pulley and is secured with the bolts supplied. The new serpentine water pump pulley is also a simple slip over. 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.
Helpful install hints 1. 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. 2. 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. This popular Perkins Marine 135 or 165 HP. engine, and all other engines operate much smoother, quieter and virtually eliminate belt dust with a serpentine pulley upgrade kit.
