5
Install the wave washer and then the drive side bearing shield onto the spindle, making sure the bearing
shield is oriented correctly. The
stepped lip on the
bearing shield
should face the bottom bracket shell.
ADVICE
The drive side bearing shield inner diameter has a circular design. The non-drive side bearing shield
inner diameter has a “flower” like design.
6
Gently and completely insert the drive side crank assembly spindle through the bottom bracket cups until the
non-drive side splines come through the non-drive side bottom bracket cup, and the spindle stops.
7
Install the non-drive side bearing shield onto the spindle, making sure the bearing shield is oriented correctly.
The
stepped lip on the
bearing shield
should face the bottom bracket shell (not pictured).
8
Apply grease to the threads of non-drive side crank bolt. Place the non-drive side crank arm on the spindle
and use a 8 mm hex to torque the crank bolt to 48-54 N·m (425-478 in-lb).
Check the assembly for play by rocking the crank arms back and forth away from frame. If the crank moves, tighten
crank arm bolt until no play is detected. If maximum torque of 54 N·m (478 in-lb) has been achieved, remove the crank
arm from the spindle, apply additional grease and repeat installation proceedures until play is eliminated.
PEDAL INSTALLATION
9
Grease the pedal threads and install the included pedal washers (a, Figure 9). Thread the pedals into the
crankarms, and torque to 47-54 N·m (416-478 in-lb).
ADVICE
The drive side is right hand pedal-thread. Non-drive side is left hand pedal-thread.
MAINTENANCE
Important: use only water and a mild soap to clean crankset and bottom bracket. Do NOT use a pres-
sure washer.
ADVICE
If creaking of the assembly occurs, check that all parts are torqued to specification, and grease is liberally
applied on all surfaces noted. Verify that chainring bolts are torqued to 8-9 N·m
(80-90 in-lb). If creaking continues, consult your local Truvativ dealer for assistance.
ATTENTION
Bearings require regular maintenance. Re-grease bearings after 100 hours of use in dry conditions or
immediately following any significant exposure to water; such as riding in heavy rain or through water
crossings.
REMOVAL
10
Use the self-extracting crank bolt assembly or crank puller (if applicable) to remove the non-drive side crank
arm. Use a rubber mallet to gently tap the end of the crank spindle towards the frame, and slide it out of the
bottom bracket. Remove the bearing shields from the bottom bracket cups (not pictured).
The bottom bracket should be removed by applying force on the internal adapter cup wall (not the bearing)
(not pictured).
