The first step is to remove the CV cover. On the RZR 900, it’s
on the left. You’ll find it easier if you remove the wheel and
the bottom or top shock mount.
The primary clutch is the one in front on the motor. It engages when the motor rises above idle, and is controlled by
three weights and a spring. The secondary clutch in the back
changes the final drive ratio as wheel speed increases. With
our 30-inch tires, 27 inches is stock, our RZR would be over-geared if left alone. The EPI kit corrects this.
Polaris provides a tool that lets you relieve belt tension so it
can be removed. The primary clutch itself is easy to remove
with a puller. The EPI part number is PCP8, and it sells for
$59.95. Install the puller in the center and use an impact
wrench to tighten it.
There are three weights within the primary clutch that need to
be replaced. Simply remove the pivot bolt on each and reassemble with the new EPI weights. Reassemble the primary
clutch and move on to the secondary.
The primary, or drive,
clutch is under
but can be
without special tools if you
are careful. In
this case, we
used the EPI
to relieve the
the six bolts.
This tool is
the secondary clutch,
but it worked
well here too.
Before disassembly, mark
the clutch, the
spider and the
so they can be
the same orientation.
you’ll see this
spring. It has a
