Thread: Repairing Missing Wheel Stud on IIA

You'd have to drill out to match the size used for the splined section to pull into but there are other issues.
The stud length varies depending on whether the nuts are double sided (chamfer both sides) or not so you might find the thread exposed ends up too short depending on what wheelnuts are fitted.
There is also a recess that the splined type fit into, without this the stud exposed will be shorter still.....

Just recently found a 9/16" BSF tap to clean out nuts and the hub. As you've found though, it just depends how much damage is done as the stud unthreads.

Unfortunately the old threads got torn out. The replacement stud can be pushed through the hole without actually turning so there's nothing left for a tap to work with.

I'll have to have a look at the lengths. I don't remember noticing a significant length difference, but I haven't put the splined stud against anything.

How big would the hole be around the splined section? I wouldn't have thought that it would be much more than the body of the stud. There needs to be some interference between the hub and the splines for these to hold doesn't there?

Cheers,

They have been fixed with a dob of weld on the inside many a time..... 🤔

A bit more than the measurement at the base of the splines. I had a hub with the press in studs removed but only a few weeks ago pressed in new studs so I don't have anything to measure unfortunately.

As cjc_td5 mentioned welding is a possibility if you remove the hub. The only issue is that you are joining steel & cast iron.


Colin

The other possibility would be to ream or drill the hole to take a wheel nut turned down and with a flange left for the inside and with a slot to spread the standard stud. The hole and the diameter of the turned down nut should be an interference fit, and the nut pressed in, or it could be pulled in by the stud and nut. Easier if left in the freezer for a couple of hours.

Ive got four spare s2a hubs here three of which have good studs and one that has been repaired sometime in the past but is still good. All 4 hubs have near new surplus ex military bearings fitted as well. Pm if u need any.

Cheers Rod

Didn't read half of what was said, but my series 2A had a missing / broken stud and a loose one so I just welded the loose one on and glues a nut with some masking tape packed inside of it with some body tar orotund the outside to get it past rego :'D

Find out the Root Diameter of a replacement stud.
drill to that size.
insert the stud
place a suitable washer over the stud
put a flat nut on
wind it in with that, dont use a wheel nut. use a wheel nut on backwards if you have to..

Dont pull it in with the taper side. (dont ask) (ok bad things busted nut and cracked a hub)
