.

4. When the bottom bracket is fully installed, unscrew the headset press tool and

carefully remove.

5. Check the bearings for rotational smoothness. If the bearings feel rough, it may be

an indication the cups are not perfectly aligned in the BB shell. It may be necessary

to reinstall the bearings to assure the bearing cups are properly aligned.

the spindle engagement teeth.

plastic covers of the bearing cups.

⑥

on the non-drive side of the spindle. Make sure

the engagement teeth are fully exposed on the non-drive side of the bottom

bracket.

5. Install the left crank arm and tighten to manufacturer specifications. If necessary,

install separately available shims to take up any play. If there is still play, DO NOT

tighten even more, inspect BB shell for proper tolerances and re-install BB and

crankset.

IMPORTANT:

* Before installing the bearings, use a reaming tool to ensure the

bottom bracket (BB) shell is clean and free of metal chips, dirt

and excess paint.

* Inspect the BB shell for ID, ovalization or anything that could

cause bearing mis-alignment.

* Always use a calibrated torque wrench to tighten crank bolts.

* The wave spring washer should not be completely compressed

for proper use.
