DISASSEMBLY
Hub parts and names are referenced on next page.
Remove the axle
1. Remove one of the thread-
ed axle end caps (Fig. 2H) by
loosening with the pair of 17mm
cone wrenches.
2. With one end cap
removed, drive the axle from
the hub shell with a soft-faced
hammer.
3. Place a broad punch
through the hub, and tap the
punch with a hammer to drive
the second bearing (Fig. 3H),
with its seal, from the hub.
4. If needed, remove the
second bearing from the axle. To do this, clamp the
middle of the axle, loosen the end cap, and remove it.
Support the bearing and tap the axle out with a soft-
faced hammer.
Clean and inspect the parts
1. Wipe old grease or debris from the hub bearing
seats.
2. Normally, bearings are not re-used. If you are re-
installing an old bearing, wipe off any grease or debris
from both the inner and outer surfaces.
Do not use solvent on the bearing, as the solvent will
contaminate the grease. This may cause bearing failure.
Lubricate bearings and threads
1. Lubricate the threads on the axle with Wrench
Force™ synthetic grease, or a similar product.
2. Lightly grease the inner and outer surfaces of
each bearing.
ASSEMBLY
1. Press a new bearing onto
the axle with a bearing press.
Note: the black seal faces out (Fig. 4H).
2. Place the hub seal onto the
axle, and thread on the axle end
cap. Clamp the middle of the axle
and tighten the axle end cap with
the 17mm cone wrench.
3. Press the bearing, with the
axle attached, into the hub.
4. Press the second bearing into the hub.
Note: the black seal faces out (Fig. 4H).
5. Place the hub seal over the bearing, and press into
the hub shell.
6. Thread on the second axle end cap, and tighten with
the 17mm cone wrench.
Do not over-tighten the axle nut. The axle should turn freely with no lateral play in the hub shell.
