Crankset Troubleshooting

This section describes problems that occasionally occur, and possible solutions. If these 
solutions do not solve a problem, contact Customer Service.

Bearing Play In A GXP Crank Or Bottom Bracket Assembly

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 
insufficient torque on the non-
drive crank arm. 
In rare instances a tolerance stack 
can be created by the five 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 the torque 
specifications (see page 38). Most issues with play in 
GXP crankarms are resolved when the arms are properly 
tightened.

If this does not solve the issue, add a 0.5 mm washer/spacer 
(PN 294162) between the wave washer and seal  
(Figure 14.39) 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 
sufficient, 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 the torque 
specifications (see page 38).

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.
