Aeris Hubcap Assembly Installation
• Place the hubcap gasket over the tubing before inserting it into push lock fitting on hubcap. If you are
installing a grease application hubcap, make sure to follow recommended manufacturing guidelines for
putting grease in bearings before you install the hubcap.
IMPORTANT: Make sure grease is applied before installing grease hubcap if hubcap is a grease application.
• Install the tubing into the push lock fitting on the Aeris hubcap. Push firmly on to ensure the tubing is fully
seated. Now push the hubcap and excess airline back into the axle spindle until the flange of the hubcap is
flush with the hub. As the tubing is being pushed back into the axle make sure it doesn’t kink or bend.
• Align hubcap gasket with bolt holes on hubcap and install bolts. Install all bolts and snug down until
hubcap is seated against the hub. When all bolts are snug use a torque wrench to finish tightening bolts to
correct specification. Tighten bolts using a star pattern as shown in figure 16. Torque bolts to 12-16 ft lbs.
