Ford Wheel Hub Identification - Please Help!

[Laurence7]

This is a bit of a long shot, but I'm hoping someone out there might be able to help me.

I've got a bike-engined race car that uses the front wheel hub (or 'drive flange') from a Ford model, on all four corners of the car. I'm trying to track down which model the hubs come from, as I want to refurbish a spare set of hub carriers and fit them with new hubs.

The hubs have a four-lobe profiled shape (ie, not circular), 22 splines and the usual 4-stud pattern on a 4.25" PCD, but here's the important point; the stud holes are plain (for serrated studs) not threaded.

I believe the hubs may be from an early Fiesta, or FWD Escort, but the ones I've looked at so far have had threaded stud holes.

Does anyone have any ideas which Ford model these hubs were fitted to?

(...and for extra points, the Ford part number !)

Thanks

Definitely not Fiesta - i've been through plenty of those versions and never come across unthreaded 4 lobe arrangements.

Any chance of a photo? I'm sure that will help narrow things down!

Can't seem to upload photos at the moment - not sure why not - will try again later.

In the meantime, here are some dimensional details of the mystery Ford hubs

Bearing journal diameter: 35mm / 1.378"
Bearing journal length: 32mm / 1.260"
Seal journal diameter: 45mm / 1.772"
Seal journal length: 6.7mm / 0.264"
Bearing to flange face offset (approx): 21mm / 0.827"
Stud hole diameter: 12.7mm / 0.500" (plain, not threaded)
Stud pitch circle diameter (PCD): 108mm / 4.252"
Stud flange thickness: (thick part) 9.525mm / 0.375"
Stud flange thickness: (thin part) 7.1mm / 0.280"
Spline major diameter: (approx) 25.5mm / 1.004"
Spline minor diameter; (approx) 23.7mm / 0.933"
Number of splines: 22

Any one care to take a stab at what model they come from ?

[Laurence7]

Success! (just needed a slightly smaller file size to upload)

So here are the pictures of the mystery hub - see also my earlier posting for all the dimensions.

Anyone have any ideas which model Ford this hub comes from?

looks like mk 3 escort/mk 1/2 fiesta

[Mickyturbo]

I think its from a Mk3/4 Escort.And Im guessing they used to have threads,but someone drilled them out to insert studs,as its easier to mount the wheel on studs,then lining up a wheel and putting in bolts.

[Mickyturbo]

Ok,its not a mark 3/4 escort hub,have one in my hand and it has 23 splines!!

[MHM]

Anyone else count 23 splines in that pic ?

Yes

[jasonxr2racer]

they will be Later Mk1 Fiesta and XR2 23 spline hubs and were also carried over to MK2 Fiestas

defo been drilled out as Ford only did studded ones on Mk3 upwards

[Laurence7]

Guys - Just returned to this topic - I thought it had died.

Thanks for the responses and yes, 23 splines, not 22 - how could I get it so wrong !
