What is a hub and rotor?

Rotor Hubs. The rotor hub is the component that usually holds the blades and connects them to the main shaft of the wind machine. It is a key component not only because it holds the blades in their proper position for maximum aerodynamic efficiency, it also rotates to drive the generator.

What is the retention screw on a hub?

Certain OEM and Aftermarket hubs and rotors have a retention screw that holds the rotor to the hub assembly wheel flange. The purpose of the retention screw is to aid in the vehicle assembly process at the factory. Depending on your application your vehicle may or may not have the retention screw used…

Why are there screws in the rotor of a car?

Some people seem to believe the rotor screws are just an assembly requirement (during initial manufacturing) and solve no purpose in-use. The rotor is centred by the wheel’s central bore and held in place by the lugs nuts when the wheel is put on. Others debate its the screws that centre the rotor…

Can a hub assembly be assembled without a screw hole?

Some hub assemblies may have the retention screw on the old part being removed from the vehicle but the replacement hub and/or rotor may not have the screw hole. If the new replacement part does not have the retention hole, the parts can be assembled without the old retention screw being used. Figures 2 and 3 below are the same part number.

Are there any holes in the new rotors?

The new OEM rotors don’t seem to have holes machined for the purpose. I can’t afford them to sit 1-2 mm above the surface, since that would foul with my alloys sitting flush with the hub face. I read up on this topic online, but the debate is unresolved.

What is a preset drive hub and rotor assembly?

PreSet ® Drive Hub & Rotor Assemblies ABOUTTHISMANUAL About This Manual˜This service manual applies to brake rotors designed and manufactured by ConMet for air disc brake applications. ConMet also manufactures hub assemblies equipped with brake rotors designed and manufactured by other brake companies.

Where is the wheel hub assembly on a car?

To see the wheel hub assembly, you’ll need to remove the wheel and then remove the brake caliper and brake rotor. On most late-model vehicles manufactured since 1998, there is a wheel hub assembly in each wheel.

Certain OEM and Aftermarket hubs and rotors have a retention screw that holds the rotor to the hub assembly wheel flange. See Figure 1. The purpose of the retention screw is to aid in the vehicle assembly process at the factory.

How do you hold the break rotor while doing this?

The bolts are on very tight and often take a lot of torque to remove. How do you hold the break rotor while doing this? A vise may or may not work and when you go to torque the new rotor back on the hub, holding it in the vise car damage it.
