Continuing from last week’s Workshop Wednesday post regarding BB30 and PF30, this week we’ll take a look at how to remove and replace the bearings in your Campagnolo Power Torque crankset.
Soft faced hammer
14mm allen key
Flat blade screwdriver
Crown race setter (not shown)
Cardboard pads (not shown)
1) The first step is to remove the left hand crank. Using the 14mm allen key, remove the crank bolt and washer by turning it anti-clockwise.
6) With both bearings removed, install the smaller of the two rubber seals onto the crank axle. Next apply grease/anti-seize to the axle and using a crown setter knock the replacement bearing down the axle. Follow this with the circlip. Apply grease/anti-seize to the inside of both BB cups and loosely press the non-drive side bearing into place by hand before fully seating the bearing by tapping gently with the soft face of the hammer.
7) Slide the crankset back through the bike and install the compression spring then the thicker rubber seal onto the crank axle. Grease the axle splines. Align the left hand crank with the splines on the crank axle and secure using the crank bolt and washer with a 14mm allen key. Tighten to 42Nm if using a torque wrench. Lastly, hook the retaining clip around the drive side BB cup.
