Hey Everyone, new to here. Jag is a 74 E-type V12. It was my late father in laws Jag, and it has been in our garage for the past few years. As you can see from pic below, tire is flat, and I am trying to remove the wheel to take it to get the tire fixed. I cannot for the life of me figure out how to remove the cap( which I'm assuming has the lugs behind it ). I think it just unscrews? Is this correct? Are the lugs behind the cap? If it does unscrew, I can't get it to budge. Any tips? Any help would be greatly appreciated! Thanks!

 

you have a three eared knock off there, not a cap of any sort, no lug nuts underneath. Hopefully if you search in the 'boot', you will find an adaptor that you hold against the knock off, then smacking it carefully with a lead hammer will allow the knock off to loosen. Check the printing on the knock off before smacking to figure out which way to turn it.

Yes, it avoids having lugs on the spinner, so maybe a safety thing. Here in the UK, most of these knock-on wheels have spinners with lugs so you can whallop the spinner to loosen or tighten it. YOu can see the direction arrows and text on the spinner. For the lug type you use a copper-headed hammer so you don't damage anything, but for these the special tool can be made with longer lugs so needing less force, indeed, I think there were some wooden ones made of thick plywood at one time.

Have a look on this web page, you'll see the two types.

Thanks, so your saying there should be an adapter that goes over the cap I can hit to then loosen it? It does have an arrow going counterclockwise so I'm assuming that it the direction it loosens. So once I get that off, the wheel will just slide off? Okay, forgive me for not knowing, but what is the " boot "? If he still had the adapter, is this where it would be? Sorry, but I'm a truck guy so this Jag thing is all New to me, lol. Thanks

 

boot = trunk for us in the colonies... Where the spare and all the tools including the adaptor should be hiding. The adaptor should have three ears to smack on and is made of a brass alloy. If the arrow is counter-clockwise and says "undo", or "loosen", the smacking should be straightforward. The threads are reversed on opposite sides of the car. Removing the wheel should then be easy by pulling straight out to separate the splined hub from the splined wheel.


If smacking does nothing you might have a frozen wheel and may need other means to remove the knock off.


a shop manual should be the next thing on your wish list.

Hello bay country16,
Typically, the Series 3 E Type was supplied with wingless Knock On/Off Spinner (the type shown in the picture attached to your Post). For this type of spinner, a Knock On/Off spanner as shown below should be included in the tools that are supplied with the car.



There are cut outs on the back surface of the spanner that allows it to pass over the small lugs on the Knock Off Spinner. Once positioned on the spinner, rotate it (slightly) in the direction to undo until firm resistance is felt (an arrow and script on the face of the Knock Off Spinner will give you the direction). Whilst holding the spanner in the position of resistance, strike the most conveniently positioned lug of the spanner a sharp, heavy blow with a soft hammer to impart rotation of the nut (spinner) in the required direction.

If the nut (spinner) will not budge, carefully heat the nut (spinner) with an electric hot air gun, or gas torch until just too hot to touch. At this heat there will no chance of discoloring the chrome plating, but sufficient to expand the nut (made of a brass alloy). Once hot, move quickly to position the Knock Off Spanner and strike with soft hammer as explained earlier. When using heat to expand the nut, you must move quickly to attempt to undo it so as to avoid the heat soaking into the wheel hub and the dimensions of the nut and wheel hub equalizing.

Regards,

Brent

 

So... some of us are curious, did you get the wheels off?
