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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
