MODEL 282 HUB

ZIPP model 282 hubs were in production from late 1999 through 2001.

282 hubs manufactured until 3/00:

  1. Loosen and remove either the drive side axle end nut or non-drive side axle end cap by fitting a 17mm open end wrench to each and turning in opposite directions (standard right-hand threads on both). Unthread the end fitting that loosens first.
  2. Remove the cassette body from the hub by pulling it from the drive side of the hub (the axle may come out of the hub along with the cassette body).
  3. Pull the axle from the non-drive side of the hub body if necessary. Note the steel spacing sleeve between the cassette body and the drive side hub body bearing: this must be replaced at reassembly to prevent hub bearing and cassette pawl damage.
  4. Clean the freewheel ratchet ring and pawl assembly with a solvent that is safe for aluminum and neoprene rubber (WD-40 or similar product works well) and wipe or blow dry.
  5. Relubricate with lightweight grease that is non-corrosive to aluminum (preferably PTFE containing synthetic based grease) and reassemble the axle and cassette body to the hub.
  6. Lubricate the axle threads with grease, then install and finger tighten the drive side axle end nut and non-drive side axle end spacer.
  7. Adjust axle end spacing on both sides by threading the nut and spacer back and forth along the axle until there is an equal amount of axle stub on both ends of the hub when the end nut and end spacer are tightened against their bearings.
  8. Tighten end nut and end spacer to 10Nm / 88lb. In.

282 hubs manufactured after 3/00:

  1. Insert a 6mm allen wrench into the non-drive axle end, then loosen and remove the drive side axle end nut with a 17mm open-end or box-end wrench while holding the axle with stationary with the allen wrench.
  2. Remove the cassette body from hub by pulling it from the drive side of the axle.
  3. Remove the axle from the hub body by pulling it from the non-drive side.
  4. Clean the freewheel ratchet ring and pawl assembly with a solvent that is safe for aluminum and neoprene rubber (WD-40 or similar product works well) and wipe or blow dry.
  5. Relubricate with lightweight grease that is non-corrosive to aluminum (preferably PTFE containing synthetic grease) and reassemble the axle and cassette body to the hub.
  6. On 282 hubs marked "USA" special care must be taken not to pinch the rubber seal ring in the hub shell when installing the freehub body. If needed, the seal may be removed from the hub shell. To reinstall, place the seal in position on the back flange of the freehub body and install both body and seal in the hub shell at the same time taking care not to pinch the seal. This procedure applies only to hubs marked "USA".
  7. Lubricate the drive side axle threads with grease, then install and tighten the drive side axle end nut snugly. Warning: Fine pitch aluminum threads.Do not over tighten!
  8. Tighten nut on both sides to 10Nm / 88lb. In.

282 Rear Hub Bearing Replacement

Hubs made until 3/00:

Remove hub axle by loosening drive and non-drive side axle end nuts with 17mm wrenches, only one axle nut will loosen. Slide the axle out of the hub and remove the cassette body/pawl holder.

Hubs made after 3/00:

Insert a 6mm allen key in one end of the axle to hold it while loosening the non-drive side axle end nut with a 17mm wrench. Slide the axle (with cassette body/pawl holder) from the drive side of the hub body. The cassette body/pawl holder can be removed from the axle by holding the axle with the 6mm allen key, then removing the drive side axle end nut with a 17mm wrench and pulling the cassette assembly from the axle.

All hubs:

  1. Insert a flat-faced punch through the drive side hub body bearing and use the tip of the punch to gently push to one side the spacer tube separating the two hub body bearings.
  2. Use the punch and a small hammer to remove the non-drive hub body bearing by gently tapping against the back of the bearing ID ring on alternating sides until the bearing is worked out of the hub.
  3. Remove the aluminum spacer tube from the hub body.
  4. Remove the drive side hub body bearing as in #2.
  5. Insert a flat-faced punch through the cassette body ratchet pawl holder and use the tip to push to one side the spacer separating the two cassette body bearings.
  6. Remove the outer bearing from the cassette body by using the punch and small hammer to tap against the back of the outer bearing ID ring on alternating sides until the bearing is worked out of the cassette body.
  7. With a pair of snap ring pliers, remove the bearing retaining ring from the interior of the cassette body.
  8. Using the hammer and punch, gently tap the inner bearing from the cassette body as in #6.
  9. Replace all bearings in reverse order by pressing on the bearings' outer diameters using the appropriate sized bearing press tool.
  10. Re-install axle, cassette body and axle nuts.
  11. In mid-2001 the "USA" made version of the hub was introduced due to delivery and production issues with our Swiss supplier. On 282 hubs marked "USA" special care must be taken not to pinch the rubber seal ring in the hub shell when installing the freehub body. If needed, the seal may be removed from the hub shell. Place the seal in position on the back flange of the freehub body and install both body and seal in the hub shell at the same time taking care not to pinch the seal. This procedure applies only to hubs marked "USA". Note that "USA" and "Swiss" freehub bodies are NOT interchangeable.
  12. Tighten axle nuts to: 10Nm / 88lb. In.

282 Pawl Spring Replacement

The engagement pawls of the ZIPP 282 rear hub employ a single spring to power the clutch mechanism. The spring is a round steel wire hoop 1inch or 2.5cm in diameter. It is open on one end. The spring sits in a deep groove that circles the freehub body. The spring holds the pawls in place and provides the force to engage the pawls into the ratchet ring of the clutch mechanism. If the spring is bent or broken complete pawl engagement will not occur. Symptoms may include skipping or locking of the ratcheting mechanism.

To remove the pawl spring:

  1. You will need a very small screwdriver or pick-like device to help ease the spring from the retaining groove. An unbent paper clip, a spoke or similar stiff wire also works very well.
  2. Remove the freehub body according to the normal procedure. (Instructions are available.)
  3. Locate on the spring retaining groove a small indented or notched area that is perpendicular to the main groove. This is the spot that indicates the open ends of the spring on either side of the indented area.
  4. Locate the pawl nearest the indented area.
  5. Looking down at the end of the freehub body, pull the pawl with your fingertip to a fully open position. As you do so, the spring will rise in the groove.
  6. With the pawl fully open, insert your tool into the pawl pocket under the spring. Gently pry the open end of the spring over the lip of the retaining groove towards the nearest end of the freehub body.
  7. Resting the open end of the spring on the freehub body, use you fingertips or tool work the spring out of the retaining groove and off the end of the freehub body. You will need to press each pawl fully closed/down as the spring passes over the pawl. The pawls are now loose in their pockets and can easily fall out.

Pawl spring installation:

  1. With the freehub body pawl area facing up, place the pawls in their respective pockets.
  2. Locate the notched or indented area that is perpendicular to the spring retaining groove.
  3. With the open ends of the spring lined up with the notch, place the spring in the retaining groove exactly on the opposite side of the spring opening and notch.
  4. Gently spread the spring around and down over the end of freehub body until the spring snaps into the retaining groove.
  5. Re-lubricate the pawl with lightweight grease that is non-corrosive to aluminum (preferably PTFE containing synthetic based grease) and reassemble the axle and cassette body to the hub.
  6. Reassemble the hub.

282 USA and Swiss Hubs

Delivery and volume issues with our Swiss supplier in 2001 resulted in the mid-year introduction of the USA produced version of the 282 hub. The two hubs resemble each other superficially, but the free hub bodies are NOT interchangeable.

When switching freehub bodies from Campy to Shimano or vice versa, or anytime a new freehub body is installed, you must know which 282 version you have and install the correct version for your hub.

The USA hubs are easily identifiable by a laser etched "USA" in the center of the hub shell between the flanges. On all 282 hubs as they are supplied from ZIPP, a ZIPP logo sticker is applied and circles the narrow center of the hub shell. The sticker does not completely encircle the hub and in the gap is where you will find the "USA" laser etched designation. Swiss hubs have no laser etching or other designation.

282 freehub bodies are not interchangeable with any other model of ZIPP hub.
