Fitting instructions

• Put the bike on a stand so the rear wheel is off the ground.
• Undo the rear axle nut and pull out the spindle.
• Lift the chain off the sprockets and take out the rear wheel.
• Take off the old axle blocks.
• Remove the bolts from the old axle blocks.
• KTM only: take the spindle out of the old axle block. This may need some heat and a vice, so take care not to damage the spindle.
• KTM only: fit the spindle into the new axle block, using red threadlock.
• Clean the swing arm area so it is free from dirt and debris.
• Place the new RFX axle blocks on the swing arm, checking that they are aligned and the bolts are in place.
• Clean the spindle and axle nut.
• Grease the spindle and wheel spacers with waterproof grease.
• Lift the wheel into place and put the chain back on.
• Push the spindle fully through and refit the axle nut, but do not tighten it fully yet.
• Use the axle blocks to square up the wheel, then adjust the chain to the correct tension (see your owner's manual for the figure).
• Tighten the axle nut to the torque given in your owner's manual.
