The minimum recommended installed gap setting is 1 turn + 0 tick marks and the maximum
installed gap setting is 1 turn + 4 tick marks. Any installed gap setting between these two points is
a valid setting.
Friction Plates and Wear
Modern friction plates have a remarkable ability to withstand hard use with little or no wear.
However, some OEM and aftermarket friction plates trade-off an increase in wear for other
benefits. To minimize maintenance and maximize the durability of your clutch, we recommend
Rekluse friction plates when your clutch pack has worn. Rekluse friction plates are OEM quality
or better and are designed for minimum wear under hard use: a perfect match for your Core EXP
clutch.
When clutch plates are new, they will break-in and the clutch pack height will shrink substantially
in the first 10-30 minutes of riding. Break-in of the clutch plates can continue much longer
depending on use.
When clutch plates are new, the installed gap should be set to just 1 full
turn
. After break-in, the
installed gap must be re-set
. Be prepared to reset your installed gap
immediately following break-in and possibly again after the first one or two rides. The complete
break-in procedure can be found in the Rekluse Core EXP
Installation Guide
.
The steel drive plates generally do not need to be replaced unless they become warped from
excessive heat.
The EXP friction disk has friction pads bonded to it that may wear over time and need
replacement. The friction pads can also be overheated requiring replacement.
The friction pads should be a greenish brown to dark brown color. If the friction pads are black in
color, they have been overheated and the EXP bases must be replaced. The minimum height of
the friction pads is 0.005” (0.127mm). The friction pad height can be measured by simply
measuring the overall thickness of the EXP friction disk across the friction pads as shown below.
The overall thickness measurement must be larger than 0.416” (10.57-mm)
