My mistake. Upon revisiting the scene of the crime the bearing outer races are in as per the manual. 65 is a bad age for memory and recall, believe me!. Anyway, I have replaced the outer races and the oil seal. So, weather permitting, tomorrow will be re-assembly day. Just a quickie. The guide to replacement on this site is great. Just one question. On grease replacement it is mentioned that you pack the knuckle with no more than 100ml of grease. As grease is not a liquid that would be difficult to measure! Would I be right in assuming that 100ml is the same as a 100grams. Being of the age that my time at school was the Imperial era, although I can work with both systems I still like to ensure that I have the relationships correct.
Cheers for now, mickt

Any advise on replacing the 4 14mm bolts I d imagine quite expensive from Suzuki and replacing the driveshaft circlip, another Suzuki part?

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.

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?

Which?
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.

Helijohn-Ref your remark about a six sided ring spanner. The point of contact with that would only be the six corners of each flat. Hence when it is worn the corners of the flats are always worn away. The twelve point rings and sockets increased this point of contact to 12 points but are still not as effective as the metrinch design. Please see attached photos' of a socket and combination spanner from my kit. The socket is marked "3/4 & 19mm" and the spanner "15mm & 19/32". Sorry for the quality of the pics!
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.
Cheers, mickt

Using google I found a calculator that confirmed what I thought, that 100ml is 100gramms. Its nice to have something confirmed when you do not always work in metric!
That conversion is for water. As standard grease is considered to be 12% lighter than water 100ml will equate to 88grams!!(found on Google!)
