So when you say replace with a higher grade where do you get these specialist bolt from? Or do you mean just use a bolt of the correct length/diameter not worrying about the serrated bit?
FACADE- When you say I have the bearings in wrong way, which way are they in on yours? Looking at the axle with all the bits removed with the upper and lower bearings at 6 & 12 o'clock the lower one sits in the outer race and is lifted out into the axle cavity and the upper one goes into the upper outer race and if not held there would just fall out, on mine. Surely you are not suggesting they are fitted the other way round?
MARKYP2000-What sort of torque figure do you think is required for these bolts? Very tight would seem to be about right for me, just like the brake calliper retaining bolts. They are about the same thread size. What do you think?
Upon getting round to cleaning all the bits for refitment I found the upper bearing had broken up, one of the rollers fell in two whilst cleaning it! The "shim" fitted looked like a bodge as the inner circumference was not a perfect circle. More like it had been filed to fit! Me wonders if fitting that caused the bearing to give up the ghost!
Ah well, onward and upward!
As for 100mlgrease, I just worked on the fact a tin is 500ml and didvided it up by eye. I read 150ml for the outside of the Barfield but I just did it by eye too. I am always wary about overpacking a knuckle but I bet some pack plenty of grease in the housing to fight of water.
It is common on other makes for peeps to cut their own shims for the king pin pre-load out of things like coke cans.
It is possible to get serrated spring washers to use with the substitute bolts but I am wondering if it is necessary.

The 8 king pin bolts are said to be 18 ft/lbs. The four that hold the disc dust cover are 36 ft/lbs but I had to wing it as none of my torque wrenches would squeeze in there. That is averagely tight.

The design is an American patent. I find they are good on the worn stuff but not as good as "normal kit" for the un-troublesome nuts and bolts.

That conversion is for water. As standard grease is considered to be 12% lighter than water 100ml will equate to 88grams!!(found on Google!)
