Well it has been a while since I posted about the king pin replacement.
It hasn't gone very well - it hasn't gone well at all.
I've reached the conclusion that the only way to do this job successfully is to have the special tool SVO1171
With out SVO 1171 the chances of success are slim - very slim.
In the spirit of education and owning up I'll show the disaster =>
I bought a 1990s vintage adjustable hand reamer on the bay of ee that will adjust between 18mm and about 20mm (I think). It is an OK bit of kit but isn't of the same quality as a normal fixed size hand reamer.
It did work but as you can see it isn't long enough to go through both of the bushes on the spindle assembly...
...I wasn't hopeful but thought it was worth a try - the adjustable reamer had been bought - so I reamed out the hole to fit the 19mm king pin.
As you can see in the next picture the alignment with the other bush was a world away from where it should be =>
Hashtag **** up!
Oh well ten euro's wasted - newly reamed bush was pressed out and replaced with another new one.

So what to do - what to do?

I came up with two options
1) Go to a machine shop and ask for help
2) Find the special tool
Option 1:-
Machine reamers are shorter than the hand reamers and they don't have (that much of) a tapered leading edge to help guide the ream through the two holes.
After consulting three machine shops I found someone who was willing to mount the spindle in a dividing head (so it could be flipped accurately through 180 degrees) and then ream the bushes to size from either outer side.
I thought this would probably involve a labour cost of about 60 euros and probably the need to have two more bushes fitted (!) so I decided option two was best
Option 2:-
SVO1171 is as common as rocking horse ****.
I contacted every local Volvo dealership to see if they still had the tool - no dice
I contacted every national classic Volvo specialist to see if they have the tool - no dice
I contacted the VkV club I'm a member of here in Holland and found someone who said they have the tool
?!Success!?
I went to visit the club member today. Really nice chap - very helpful - but it turned out the tools he's got aren't SVO1171 - shame. He's convinced he did the job thirty years ago with the special tool but can no longer find it...
...luckily someone was smiling down on me: He said he felt so bad that I'd come to see him for "no reason" that he was willing to swap my dismantled parts for a whole second hand one that was in good condition.
Like I said - a nice chap.
Whilst I'd rather have had a brand new - made by me assembly - I swallowed my pride and grabbed the offer with both hands!
So the moral of the story is - don't start to replace king pins on a PV with out having SVO1171 - SVO 1171 is in my opinion the best solution for this job - but if you're pushed, a dividing head and several machine reamers ranging from 18 to 19mm might just get the holes suitably aligned for the king pin to fit correctly (but I have a feeling you're going to need a bit of luck for that to work)
If you look at the book - SVO1171 is long enough to go through both holes and that whilst one hole is being reamed it is being guided by the other hole - this is the only way I can see these holes will end up being perfectly aligned (which if you think about it is blinking crucial)
