REAR HUBS - DRIVESHELLS
Chris King incorporates its RingDrive system inside the hub body and uses a driveshell to retain and support the cassette. The Universal Hub Tool is designed to perform complete disassembly and reassembly of ten legacy and current production Chris King driveshells. Simplified diagrams for removing and installing the bearings in these hubs are provided in Figures G through J. Use the table below and the type of bearing at the cassette end of your drivehshell to identify the correct Figure for your driveshell.

ABOUT THE CHRIS KING UNIVERSAL HUB TOOL
T-handle: The T-handle is an assembly of seven factory-assembled parts: a threaded T-handle body, strike, bushing, bushing o-ring, handlebar and two handlebar retaining rings. The T-handle delivers the force required to remove bearings when hammering on the strike and the press to install bearings using the handlebar, which can be extended to one side for additional leverage. If you want to fix the position of the handlebar, locate the handlebar where you would like it retained and place an o-ring or layer of electrician’s tape on either side of the T-handle head.
Extension Shaft: The extension shaft screws into the end of the T-handle compressing the cone and split-rings providing a surface for engaging and removing bearings. A 4mm hex wrench can be inserted into the end of the extension shaft to provide increased leverage.
Cone and three Split-rings: The cone slides into each of the three split-rings expanding them to a size that engages the outer race of a bearing during removal or engages the face of a retainer when removing the drive system and bearing from a rear hub. The three split-rings are laser-marked 1, 2 and 3 and the following instructions may use the numbers 1, 2 and 3 when referring to the individual split-rings. The split-rings are also assembled with color-coded o-rings for easy identification: 1 black, 2 white, 3 red.
Four Guide Bushings: The four bushings are used to guide the T-handle shaft inside bearings and bearing bores during bearing removal and to press on bearings and bearing bores during bearing installation. The guide bushings are laser-marked A, B, C and D and the following instructions my use the letters A, B, C and D when referring to the individual guide bushings.
Knurled Ring E: Knurled ring E is used to retain bearings during removal and generates the force for pressing in bearings during installation. The knurled ring has a course exterior surface for gripping and side hole where a 4mm hex wrench can be inserted and gripped for additional leverage.
Spline Driver: The spline driver is used to remove the seal ring on legacy driveshells with needle bearings (except for BMX driveshells). The driveshell is held in the cog spline wrench-HG and the spline driver is rotated counter-clockwise to remove the seal ring.
Adjusting Cone Tool: The adjusting cone tool is used to assemble and disassemble two-piece axles.
Cog Spline Wrenches: The HG cog spline wrench is used to hold HG, XD and XDR driveshells when removing or installing driveshell end-caps. The MS cog spline wrench is used to hold Microspline driveshells when removing or installing driveshell end caps. The cog spline Uwrenches incorporate flats for clamping in a vise or for holding with an adjustable wrench, slip-joint pliers or channel lock pliers.
ParkTool FR 1.3: The FR 1.3 is used to remove and install end-caps in XD, XDR and Microspline driveshells while retaining the driveshell in a cog spline wrench or tightening an end cap with the driveshell installed in the hub and restrained by the drive system.
Refer to FIGURES A through J for the appropriate split-rings for servicing your hubs and driveshells
The hub tool includes one cone and three split-rings. The three split-rings have a number designation laser-marked on them and a colored o-ring to identify them. In use, the cone and split-ring are placed onto the extension shaft, the extension shaft is threaded into the end of the T-handle and the extension shaft is tightened until the flat on the cone contacts the back of the split-ring, fully expanding it. Prior to expanding the split-ring, it is placed behind a bearing or the retainer when removing a rear hub drive system and bearing.
Prior to use, expand the split-ring between the T-handle and the extension shaft and ensure the two parts of the split-ring open evenly. If the split-ring opens unevenly, (1) ensure the split-ring and o-ring are clean, (2) adjust the o-ring until the split-ring can open evenly and/or (3) lubricate the o-ring by rubbing a drop of bearing lube or chain lube on the o-ring and reinstall.
UNIVERSAL HUB TOOL GUIDE BUSHINGS
Refer to FIGURES A through J for the appropriate bushings for servicing your hubs and driveshells
The hub tool includes four guide bushings labeled A, B, C and D. Guide bushings are used to support bearings during installation and removal and center the T-handle inside bearings and bearing bores. Figures A through J use a letter to indicate which guide bushing to use on the inboard and outboard side of the hub and an arrow to indiremcate orientation. The text letters in Figures A through J are oriented upright; in actual use some of the letters on the bushings will be upside-down as shown below.
