attack and damage seals and other nonmetallic materials. Minimize exposure to
these substances and thoroughly dry hub after cleaning.
Using a toothbrush, scrub bearing surfaces, RingDrive splines and teeth, and
helical splines on driveshell with toothbrush to remove hardened grease and
contaminants.
Flush bearing and RingDrive assembly again with a light solvent-based spray
lubricant.
Use compressed air to blow all spray lubricant, old grease and contaminants out
of the bearings and hubshell. If compressed air is not available, use a clean, lint-
free towel to thoroughly wipe out interior of hub assembly and bearing surfaces.
Bearings, RingDrive and hub interior must be completely dry and free of solvents
before adding new lubrication.
Wipe dirt and other contaminants from the seals and snap rings. Avoid cleaning
the seals with heavy-duty solvent, which could cause deterioration.
Rear hub basic lubrication
Please refer to the Service of Bearing section beginning on page 9 to properly
service rear hub bearings.
Apply 1 to 2 mL of 10w synthetic oil on the helical splines of the driven ring inside
of the hubeshell assembly
Apply a drop of light chain lube (Tri-Flow™, etc) onto O-ring on driveshell. Apply a
thin layer of grease onto clean threads in driveshell.
Apply a drop of light chain lube (Tri-Flow™, etc) onto both O-rings on axle and O-ring
on QR adaptor. Apply a thin layer of grease onto clean threads on adjusting clamp
and adjusting clamp 2.5 mm hex screw.
Rear hub basic reassembly
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 firmly seated.
If outboard driveshell bearing is separated from axle, slide it onto axle with the black
seal and silver snapring facing the driveside and the white bearing retainer facing
the non-driveside.
Insert main axle, threaded (non-driveside) end first into driveshell. Continue until axle
is through the hub and driveside end is firmly seated in driveshell.
Thread adjusting clamp onto the protruding threads on the non-driveside of axle.
Insert R45 QR insert into non-driveside axle end.
Snug adjusting clamp up to bearing.
Rear hub adjustment
The R45 rear hub features an adjusting clamp and bearing spacer spring that maintain
proper bearing preload and seating.
Secure “L”-shaped 5 mm hex key in vice with shorter end of “L” facing up
With non-driveside facing up, insert hub onto 5 mm hex key so that hub can sit
freely on vice. If vice is not available, place the hub or wheel onto a flat, firm surface
with the non-driveside facing up.
Push downward on the hubshell. This compresses the bearing spacer spring in
the drive shell and ensures proper bearing seating.
