XJS V12 1986 Starter Questions
I am in the process of removing my starter, I got the down pipe, and bottom starter bolt removed. I can't seem to find the 12 point 9/16th bolt on top. I'm afraid it might have been sheared off from previous owner. Question... 1. If it was sheared off how do I gain access to remove the starter, 2. I bought a refurbished starter motor but it seems to be the heavy duty one, its much larger in size than the original, also the bottom bolt that I removed from the starter on the car will not fit through the hole on this starter. Any suggestions? Thanks. This is my first post and probaly many more to follow.

The top bolt is hard to see under the best of circumstances....even worse if buried under caked-on grease and dirt. Clean the area best as you can and have another look.
Are you sure it has the original starter? The starter may have already been changed, thus the smaller size. It is popular to install an aftermarket gear reduction starter which is smaller. Or, Jaguar itself went to a smaller starter on the V12 in later years and that might be what you have.

I have just swapped my original starter with smaller gear reduction starter. The top bolt should original be the same type as the bottom bolt. My spare engine had a gear reduction starter and the top bolt on that one was a 12 point bolt. This starter was also Attached with nuts. I'll Guess the bolt was changed because it was a bit Shorter than the original. (the original bolt touched the starter housing) The New starter from Powerlite had threads and the original bolt also fitted. It made it a little bit easier to get to, when I removed the heat Shield over the exhaust pipe. When you have got it out also check that you have the same size starter pinion. There are some with 29 mm and some with 25 mm starter pinion.

Just something different on my stock 88 the bolt was a head size of 7/16 twelve point that was in the curve of the bell housing . there is also a bracket that will hold the wire going to the starter that is connected to that bolt that has a rubber grommet in it to protect wire mine was baked hard so I replaced it. not a very easy job.but is anything on this car easy.

Think it is impossible to to get to the bolt from top of the engine. You can drop the engine by removing the rear engine Mount (transmission Mount) . That will make it easier to locate the bolt and remove it. I managed to remove it without this operation. Used a long exstension and a "knee joint" on my pipe.

Finally got it out :)
Ok so I didn't see the pesky 7/16th 12 pt. bolt at first glance because of all the crud, but I finally found it and got the starter out. So the starter I got from ebay is much larger and beefier, has anyone put one of these babies in? If yes I have 1 question. How do I attach the top 2 starter wires to this starter? Where there was a screw on the old starter, the new starter doesn't have one, but instead a spade coming off a weld?

Hey Doug have you ever seen a xjs jag starter motor this big used before? I got the motor off ebay and it says its compatible with my 1986 xjs. Also when I put the new motor in, do I need to worry about anything? Just insert and line up the screw holes and insert bolts? Right? Thanks.

If there's lingering doubt as to whether or not your new starter is indeed a Jag V12 starter then you'll have to measure (or at least carefully eyeball) the position of the little pinion gear relative to the old starter. Envision the starter bolted in place and the position relative to the flywheel. Does it like the pinion gear would engage the flywheel?

I pulled one from a Canadian VDP V12 sedan and it looked just like your big one. Also works on a 4.2 XK engine, I put it into a friends 1970 E Type and it worked just fine, same part number as the 4.2 starter.

Last wire question
Ok I have the starter in and just need to bolt up the down pipes. Last question, the 2 big wires connect on the big bolt, right, on top of each other? I can't seem to remember if they did when I took out the old starter. See pic. And the smaller 10 guage wire now has a spade on it and is connected to the spade on the starter.
