While maintaining firm downward pressure on the hubshell, tighten the adjusting
clamp onto axle until it stops against bearing. Do not overtighten.
Once adjusting clamp is in position, tighten adjusting clamp hex bolt to 10 inch-
pounds (1.1 Nm) using a 2.5mm hex key.
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.
Complete Service - Usage of the
R45 Hub Service Tool
Periodically (every one to two years), or if foreign
debris is detectable in the grease and/or the grease
looks hard or dry, a complete servicing (removal and
cleaning) of the RingDrive, driveshell and bearings
should be performed. The R45 Hub Service Tool
allows for all small parts to be pressed out of the
hub to be cleaned, inspected, replaced if necessary,
and pressed back into the hubshell/driveshell.
It is important to note that the R45 Hub Service
Tool can only be used on R45 hubs, and
cannot service other Chris King hubs without
significantly risking damage to both the tool
and hubs. Similarly, the standard Chris King
Hub Service Tool (non-R45 compatible version)
cannot service R45 hubs without significantly
risking damage to both the tool and hubs.
This tool set is designed only for working on Chris
King R45 hubs. It is not intended to be used with any
other parts or on any other hubs. Use other than
that for which it is intended may cause damage to
the tool, other products, and/or bodily harm.
Introduction to the R45 Hub Service
Tool
The tool is made up of the following parts
T-handle. This is the main part of the pressing
device. It is a long shaft with threads on one
end, and a bulbous end with a handlebar
through it. It has a steel strike piece in the top
of the bulbous end that may be struck with a
hammer or mallet. Permanently mounted to
the T-handle is the thrust collar, which should
be able to spin freely.
Driveshell bushing. This is a tube shaped
part with one end bigger than the other. It is
used when removing and installing the inboard
driveshell bearing into the drive shell.
