The S type tire changing Jack

The S type jack style was used in the MK-X, S type, 420 and possibly the 420G which is a renamed MK-X.

the same style jack was used in the Daimler 420 Sovereign, though slightly more refined than the S type's jack.
(see the last picture of the Daimler jack used in my car).

I have one of each, they both operate the same way, a large solid square "pin" fits into each jacking point after you remove the rubber inserts or "plugs".

then you crank clockwise to raise the car. Not the stablest of jacks until the weight of the car presses down on it. I do not like it's "foot", not enough "meat on the floor", however, it does the job of raising the car and I haven't had any problem with them.

The pictures below show both jacks (S tpe and Daimler 420 Sovereign). When I bought my S type, there was no Thor Hammer in the boot and someone had used the top of the jack to loosen the wire wheel spinner, damaging the "U" shaped cover on top which is welded to the 1/4" inch heavy steel frame.

I used a hacksaw and removed the original cover and had another one made at a local machine shop. I afixed it using straps and screws because I did not want to reweld it again.

If you are restoring your Jack, reproduction Shelley Jack labels are available (see For Sale in the Forum) and the exact paint colour is in Newsletter Vol. 10, No. 4.

yes, thanks, my S type jack still has the original label, as shown above. But the Daimler 420 Sovereign jack does not and it has no sign of ever having one.

I now have the Jack's Boot Bracket "Bumpers" or "buffers" in the same grey color as the Shelley Jack's grey color. They were originally black but grey looks better! :D

Another part you have highlighted that I do not have Jose. Jack Boot Bracket "Bumpers" or "buffers". I will now have to search for some.
Damm you Jose.lol.

Out of interest. Hydraulic Jack supplied with SA built CKD cars out of it's cover.

Cass,
if you can't find them, let me know.

those bumpers / buffers prevent the jack from rattling in its bracket mount even if tightened by the strap.

As I built my car to UK spec I fitted a Shelley jack. My old jack is somewhere at my restorer's in Johannesburg. I will try & photograph the next time I'm up there. I remember reading in the automotive press all those years back that the management of Jaguar Cars SA considered the Shelley Jack "to be wholly inadequate to lift a heavy car in SA conditions." LOL.


Rob,
Barratts was able to supply me with those Jack buffers (blind grommets). I found a local substitute for the big round bung stopper it rests on & cut the rounded top shroud from rubber sheet.
