Rear Hub Bearing Installation
Install a new 61903 bearing over the axle, into the non-drive side
bearing bore of the rear hub with the
orange
seal facing outward.
Slide a 6903 bearing adapter and a 17 mm (ID) over axle bearing
spacer (>9 mm length) onto the threaded rod of the bearing press tool.
Insert the threaded rod of the bearing press through the non-drive
side of the hub shell.
Slide the second 6903 bearing adapter and 17 mm (ID) over axle
bearing spacer (>50 mm length) onto the threaded rod, over the drive
side axle.
Thread the bearing press handle onto the threaded rod. Turn the
threaded handle clockwise to press the bearing into the non-drive side
bearing bore until it is hand tight.
Check for side to side axle movement in the hub. If there is movement,
repeat step 5 to press the bearings into the hub shell further.
Remove the bearing press tool.
N OT I C E
Do not overtighten the bearing.
The over axle bearing spacers must be long enough so there is no
compression on the axle as the second bearing is being pressed into
the hub shell. Bearing adapters must not contact the axle.
Use the SRAM® Butter grease syringe to apply 0.5 gram of grease
onto the ratchet ring. Use your finger or a brush to spread the grease
around the ratchet ring.
Install the shim removed during disassembly, over the axle on the
drive side of the hub shell.
