Plastic Oil Gear
From 1987 through 1999, all Vulcan 1500 models, except the Drifter, were built with a plastic oil pump gear. Several Vulcan 1500s have experienced failures of these plastic gears, causing varying degrees of damage to their engines. To date, Kawasaki has repaired every Vulcan, in the United States, that has experienced a failure of the oil pump gear, whether in or out of warranty. Our international brethren have not faired as well as it seems Kawasaki has not been consistent in it's policy, country to country. Failure rates have varied from model to model. Few failures have occurred on 1500A models, while the 1500 Classics have experienced a higher failure rate. It seems that Nomads are probably experiencing the highest failure rates. In total, the percentage of Vulcan 1500s experiencing the failures has been low, but, significant enough to cause serious concern among owners. Kawasaki Australia wasnít interested.
JOG oil gear has worked for some but not in my case. Such is Life.
My NOMAD is currently under going a rebuild even though the motor it self hasnít failed. The rebuild is necessary to change the oil gear.
