The end plates 16, 18 have an outer ring 34 with apertures 36 for hollow pins 38 to support the core 10 and a cavity 39 with flowable material 40 for balancing the hub. The pins 38 are held in place by plugs 58 which are inserted into the interior of the pin 38 and the pin expanded outwardly by compressing the plug 58 within the interior of said pin 38 to wedge the exterior of the pin 38 within an aperture 34 of the end plate 16,18 Each end plate 16, 18 may be ribbed having radially extending apertures 60 to reduce weight and to aid ventilation of the hub. |
