hex bolt. Use 2.5mm hex key as a lever to unscrew adjusting clamp.]

4. Remove axle from the main hub assembly by pushing it through from the non-driveside. [Tech note:

The outboard driveshell bearing of the Shimano-compatible R45 may or may not remain on the axle as

it is pushed out of the hubshell assembly. It will be remain on the axle in the Campagnolo-compatible

version.]

5. Remove driveshell by holding hubshell or wheel in one hand and with other hand pull driveshell straight

out of hubshell assembly.

Clean and relubricate all bearings and RingDrive by following the procedure on pages 11 to 13. When relubricating

the R45 RingDrive and helical splines on the driveshell, remember to use a quality 10w synthetic oil (such as Mobil

1® 10w-30 or equivalent).

Further disassembly requires the Chris King R45 Hub Service Tool, which is available from any

authorized Chris King dealer, or directly from Chris King Precision Components.

Reassembly of R45 rear hub

1. Lightly lubricate all O-rings and lightly grease threads on axle.

2. Insert driveshell into the hub shell; turn in a clockwise motion while letting it pull itself in. A distinctive click

sound will indicate that the driveshell is fi rmly seated.

3. If outboard driveshell bearing is separated from axle:

a. For Shimano-compatible R45: slide bearing onto axle from the non-driveside with the black seal and

metal snapring facing the driveside and the white bearing retainer facing the non-driveside.

b. For Campagnolo-compatible R45: slide bearing onto axle from the driveside with the black seal and

metal snapring facing the driveside and the white bearing retainer facing the non-driveside. Slide Bearing

Retainer Sleeve onto driveside of axle until it snaps into place.

4. Insert main axle, threaded (non-driveside) end fi rst into driveshell. Continue until axle is through the

hub and driveside end is fi rmly seated in driveshell.

5. Thread adjusting clamp onto the protruding threads on the non-driveside of axle.

6. Insert R45 QR insert into non-driveside axle end.

7. Snug adjusting clamp up to bearing.

8. Proceed to "Adjustment of R45 rear hub", below.

Adjustment of R45 rear hub

The R45 rear hub features an adjusting clamp and bearing spacer spring that maintain proper bearing preload

and seating.

1. Place the hub or wheel onto a fl at, fi rm surface with the non-driveside facing up.

2. Push downward on the hubshell. This compresses the bearing spacer spring in the driveshell and

ensures proper bearing seating.

3. While maintaining fi rm downward pressure on the hubshell, tighten the adjusting clamp onto axle until

it stops against bearing. Do not overtighten.

4. Once adjusting clamp is in position, tighten adjusting clamp hex bolt to 10 inch-pounds using a 2.5mm

hex wrench.

5. Double check adjustment by attaching wheel to bicycle frame. Check for bearing play or binding, and

readjust adjusting clamp if needed.

Note: Correct adjustment of the rear hub is necessary for proper engagement of the RingDrive. If the hub is run loose,

the RingDrive may not engage properly and could lead to permanent damage of the internal parts
