Yes, but what age is that looking at? If it’s the same as the previous parts manual picture then it proves nothing.
All models from 2008 (8A) on as shown in the photo. The earlier manual shown was the 1994 catalog.

Must admit I am struggling to see how thtis does anything.
I can see that it will only fit in one hole in the ball flange but if it is the same thread length and dia as a standard bolt and given that the axle flanges on a coiler are threaded (no nut) then it can still screw in to any axle flange position.
As the bolt head type is a double hex this is newer than any axle I have worked on so never seen one.
The area above the threads is shouldered (bigger diameter than the threads). You can see it in my picture. This is a snug fit to the machined holes in the swivel ball. The other bolts have a shoulder that is loose in the swivel ball hole allowing them to be easily screwed in once the dowel bolt is placed. The shouldered bolt precisely sets the angular alignment between the axle housing and the swivel. This ensures that the castor angle is correct and the same on both sides.

IMO I reckon they stopped bothering with them. I've only ever seen them with all the bolts the same. Would be interesting to see a more recent parts manual to see if they're still mentioned I did some googling yesterday and most seemed to supersede to the normal bolts. The only way you'd get a proper location was if there was a dowel between the parts, or a proper shoulder bolt which locates in both items in a machined hole. Would be interesting to stick a DTI on the swivel with all normal bolts in and see how much movement there actually is. With the decent proper bolts in there I reckon there will be minimal movement as the shank is a greater size than one threaded all the way.
Here is the Microcat page.
UYG500040 is the dowel bolt. It IS a proper shoulder bolt into a machined hole.
UYG500050 are the other bolts.

If it's the one on the right, is it long enough to engage with both the axle and the swivel?
And I'd like to put a calipers on both, see the difference in diameter. It looks marginally wider.
Interesting topic.
Yes, the one on the right, with the much larger diameter shoulder. Yes, it is long enough. They are the exact same length.
-
Yes, any bolt hole is fine. I like to put it in first. That makes putting in the regular ones easier.
They are not all dowels.The other six are a very loose fit in the holes.

Carrying on regardless is a selfish attitude, and potentially dangerous to others. I’m not impressed by your posturing and “big man” stance. It’s petulant and shortsighted.
Your opinion is noted. I do not agree with you and we can move on with that understanding.

Can I remind all that this is a forum for discussing Land Rover and 4x4-related matters and not for idle chat.
That statement does not match up with what is being allowed on these forums.

If you’re saying that fitting major components, working on a running engine, welding and so on aren’t dangerous, then you are lying to yourself.
Yes, I'm saying they are not as long as you know what you are doing. I've worked in heavy industry for many decades. Safety is taken seriously. This is not 1950. If you do not know what you are doing, go sit on the couch and bitch at everyone on the internet.

It’s not, if it’s at your home address, but unless you’re only doing minor tasks, you’re engaging in a task that risks injury and the need of overstretched health services.
Where else would people be working on their own vehicle? If you think working on your car is dangerous, you best leave it to someone else!

There is a 'dowel' bolt according to the parts manual, but I can't say I've ever actually seen one in all the axles I've taken apart.
They all have one. Guaranteed. You need to look carefully at them to tell.

Eh? On a coiler the castor angle is set by the PCD with unequally spaced bolts at the bottom.
As I said...most people clearly do not realize one bolt is different than the others....
The castor is set by the inclination of the swivel housing.
One of the seven bolts that hold that swivel ball to the axle is a dowel bolt. It is a machined fit to the hole in the swivel ball. This sets the angular alignment of the swivel balls precisely to the axle housing. If you miss it, the alignment of can be off be a couple of degrees. All Land Rover axles have used a dowel bolt for this alignment since day one.
If you mix them up and both dowel bolts go into one side, the other side can be a few degrees different and cause very weird road manners.
See item 10.
-
One thing that people tend to miss is that there is one special bolt per side that is a dowel bolt. It makes sure that the castor is set exactly. If replacing bolts or mixing up parts from both sides, it can be missed.

Doesn't it depend on how the electric motor is wound? And a motor developed for automotive use would have a reducing gear built in, similar to the earlier Tesla motor units.
Yes, but automotive motors are designed for more or less the same speed range. Designing for highest possible speeds reduces the amperage demands and the sizing of the motor and its wiring. In a car, you design for the smallest motor size.
If it has gearing built in, it is not a motor. It is a gearmotor (motor and gearbox unit). None that I've seen for a retrofit into a car are combination units.

Yep, a one tonne transfer box!
That does not help. You need 10:1 total gearing on road and 30:1 off road. This means you need a single speed 3:1 gearbox somewhere in addition to the transfer case and differential gearing.

Simpler. No gearbox, only a transfer box.
EVs have a gearbox. It is just single speed. You need around 3:1 more than the diffs for road use. 2 or 3 times more for off road use.

No, for the reasons mentioned above.
You are incorrect. You need to follow proper usage guidelines,, disinfecting the mask and yourself when you exit the hot area. It will protect you when used correctly. I've used this sort of PPE for many decades while working.

But they do. They do not offer much protection from GETTING the virus yourself, but they certainly do help other people from you giving it to others.
Actually a proper N95 or better respirator will protect the wearer from the virus. A normal hospital mask will not. They are designed to protect others.

The 110 manual didn't cover the wedges, I'll look up the series ROM to see what you mean.
It is in my Defender workshop manual.

For the tee seals, you need to bolt or clamp down a wedge block to guide them in without cutting. The manual shows them. They are easy to make yourself.

Gears are stronger. Halfshafts and differentials are not.

I'd rather get it now, have done with.
You say that now. When you get permanent lung damage, you might think it was not such a good idea.
The reality is that the ENTIRE POINT to isolation is to reduce the rate of spread and limit the load on the health care system. Overloading of the health care system is the main problem that will lead to excess mortality. If you are not one one that is helping to limit the spread, you are responsible for those deaths.

Swivel Pin housing

Yes. You are not going to notice unless you know they are there. It will make life easier knowing about it. Once the dowel bolt it in, then than other six go in with no fuss.
