Aluminium Hub to suit Triumph Vitesse Size Bearing
Aluminium Alloy Hub for Triumph Vitesse Type Upright. Billet aluminium alloy. These hubs in the correct size are used on Marcos, and many low volume cars that use the Triumph Vitesse upright. Can be supplied with 3 alternate wheel stud hole pitching. 3.75" pitch for Triumph Herald. There are two versions of the stub axle used. Small size Herald; large sizes Vitesse; if in any doubt please ring us and we will help you identify your version.
There are two bearing sizes and 3 options on PCD (Wheel stud spacing measured across the diameter) and a further option of a hub that has undrilled wheel stud holes. (The hub is only suitable for 4 stud wheels with a max PCD of 108mm). Should wheel studs be fitted there is then a choice of UNF or Metric and two lengths. Thus there are a 32 permutations possible.
Please note: On 3.75" PCD hubs, the head of your wheel studs will need a flat machining due to the stud holes being close to the centre material of the hub. This is because we have had the design of our hubs made stronger, meaning there is more material in this area.
Torque Setting: Due to these hubs using a taper bearing, there is no specific torque setting. We recommend tightening the hub nut up tight, so there is zero play in the hub/wheel but not so tight that the bearing binds on the upright spindle. If in doubt, please ask us, we are happy to help.
BEARING SIZE
There are two options Herald/Spitfire and Vitesse/GT6
The inner bearing is the same on both hubs only the outer bearing differs:
Herald/Spitfire Stub axle diameter for outer bearing:0.625 inches (16mm)
Hub housing Outer Diameter: 1.615 inches (41mm)
Vitesse/GT6 Stub axle diameter for outer bearing: 0.750 inches (19mm)
Hub housing Outer Diameter: 1.75 inches (29mm)
Make sure that you measure the bearing housing not the grease cap diameter.
WHEEL STUD PCD
The PCD (Pitch Circle Diameter) of the wheel studs is found by measuring from the centre of one stud to the centre of the one diametrically opposite
The measurement is across the centre of the hub.
Triumph: 3 3/4 inches (95mm)
BL Mini Sprite: 4 inches (102mm)
Ford: 4 1/4 inches (108mm)
Some cars had different PCD front to back, please double check your PCD before ordering.
