Maintenance and fitting
These units are fitted with Taper roller bearings that can be maintained.
As with any bearings it is good practice to check bearings at least every 6 months or 3,000 miles.
These can be checked in minutes with no special tools, just shake the wheel and check for play, then lift the wheel off the ground and spin it to make sure it runs smooth
If there is a problem the bearings can be taken out, cleaned and inspected.
Re greasing is also possible with these bearings.
When initially tightening the castle nut Torque to 70Nm rotate the hub through 1 full rotation then back the nut off. The castle nut then must be a maximum of finger tight just removing any free play.
Caution over tightening the castle nut will drastically shorten the life of the bearing.
We recommend the bearings are checked after the first 500miles from fitting as they can bed in.
