MODEL 182 HUB

Your hubs are sealed and can be cleaned with a soft brush, using soap and water, or using a cleaner such as a mild detergent. Removing dirt buildup from the spoke holes will increase the life of the spoke, as well as the life of the hub. Occasionally remove the cassette body from the hub and clean out the drive mechanism. It is not necessary to remove the cassette cogs for this operation. To disassemble the rear hub, insert a 5mm Allen key in each end of the axle, and turn opposite each other (standard right-hand threads). Unthread and remove the left-hand end cap. Slide the freehub body and axle out of the main hub shell. Be sure NOT to lose the small washer that fits between the freehub body and hub shell! You can now clean off the pawls, pawl spring, and ratchet ring. Simply wipe them off or use a mild cleaner such as diluted mild detergent.

The next step is to lubricate the pawls, pawls spring, and ratchet ring. To do so, use a synthetic motor oil such as Mobil 1 10W-30. Apply 1-2 drops per pawl—enough to lightly coat them and ensure a smooth action. You should also put a light coating on the ratchet ring inside the hubshell. Grease can be used in the ratchet and pawl area, but it must have an NLGI rating of 00, 0, or 1. Do not use oils with tackifying additives, such as Phil Tenacious Oil®, as these can gum up the mechanism and cause the pawls to stick.

To reassemble the hub, insert the axle/cassette body assembly into the hub shell, making sure that the small washer is between the freehub body and hub body. Push the three pawls down with your fingers and rotate the cassette body counter clockwise as it is inserted. Next, thread on the end cap, being sure not to cross thread it. Insert a 5mm Allen key into the drive side (right), and a torque wrench with a 5mm bit into the non-drive side (left). Hub assembly torque is 10Nm (88 in-lbs) for the rear hub and 5.6Nm (50 in-lbs) for the front hub.
