Always prep by laying out the parts and tools you need on the workbench for a clean install. For this job, we will need the crankset, some grease, an 8mm hex wrench and a torque wrench capable of reaching 40-45Nm along with an 8mm hex bit for the torque wrench.

Add a light coating of grease to the following locations: Each of the 2 silver bearing interface locations on the spindle, the threads inside the spindle, each of the inner bearing races on the bottom bracket.

Fully loosen the APS adjuster so that the inner preload ring if fully backed into the outer ring. Ensure the APS is fully seated into it's position on the arm.

Slide the non-drive arm/spindle assembly into your BB already installed in the frame. (Shown here with BSA BB on a crank stand).

New line.Using the long end of an 8mm hex, tighten the crankbolt clockwise while gently pushing on the arm. This will begin to draw the interface together.

Using a torque wrench and 8mm hex bit, tighten the crankbolt on the driveside arm to 40-45Nm.

Turn the APS adjuster in the direction of the tighten arrow shown on the APS until all side-to-side free-play has been taken up.

Press on both sides of the crank attempting to move it side-to-side. There should be no play when the APS is correctly tightened.
