ZRP X3 Alternator Update Kit
This Rebuild Kit includes a complete and assembled bearing pack, pulley, new crank bolt, new cover with bearing. This is everything that we recomend changing at a service interval of 1000-3000 Miles depending on use and care.
The bearing pack is fresh with new bearings and seals installed and a fresh pulley attached to a new coupling shaft. The crank bolt and bearing pack can be changed without removing the cover. The cover bearing and shafts are all upsized to reduce bearing speeds and increse service life.
