PSE USES ONLY FACTORY COUPLERS
IN ALL REMANUFACTURING
We have found many different types of odd, homemade
type couplers in the core superchargers that get exchanged through
PSE Superchargers, and all of these couplers fail. Many customers
don’t understand why they can’t just replace the coupler
to suppress the noise and keep going. The reason why is that the
coupler does not wear out on its own. You see through time that
the nose bearings start to wear at approx. 70-100k miles (sometimes
even sooner if lubrication has been compromised due to leaks).
The bearing material called “chroming” starts to come
off the surface of the bearings and then contaminates the lubricating
oil. These small, abrasive metal particles work their way between
the drive pins and the coupler and wear the moly coupler holes
making them larger causing a loose condition which is heard as
a rattling noise. The oiling system in your Original supercharger
is called an “oil bath”. That means that all the parts
inside the nose drive assembly use the same oil, including the
bearings behind the two gears. That’s right, there is two
more bearings in the same oil bath behind the two drive gears
that you can’t see. Because of the bearings already breaking
down, and because of the abrasive material lodged in the bearings
and still present in those hidden areas, replacing the coupler
is simply a temporary reduction of noise, and not a fix at all.
The supercharger will again start to make noise in a very short
period of time. This is why we don’t like to send out a
nose drive assembly when the car has more then 50K miles because
most of the time all of these bearings need to be replaced. Replacing
these bearings requires a lot of work and machinery and is best
left up to the remanufacturer.
