The crank feels loose when grasped at the pedal end and rocked side-to-side.
Cause Solution
Wave washer not
compressed fully
This is usually caused by
insufcient torque on
the non-drive crank arm.
In rare instances a
tolerance stack can
be created by the ve
critical parts: non-drive
bearing, drive bearing,
drive-side seal, bottom
bracket shell, and axle
length.
First, verify that the crank has been tightened to 420-480
Lb•In (50-57 Nm). Most issues with play in GXP crankarms
are resolved when the arms are properly tightened.
If this does not solve the issue, add a 0.5mm washer/
spacer (PN 294162) between the wave washer and seal
(Figure 53) to increase the bearing preload.
Spline of GXP
crankarm is
undersized
+ We have seen some
variation in the
tolerance of GXP
crankarms.
+ If the installation
torque is not
sufcient, the crank
arm will not completely
compress the shield
and bearing race.
Remove the crankarm and re-install with plenty of grease.
Verify that the crank has been tightened to 420-480
Lb•In (50-57 Nm).
Re-check the bearings after installation. The GXP
axle spline is tapered, so it requires that the crank be
completely tightened to seat on the axle.
