Pardon more on this endless subject. Is the Haynes manual wrong when it states the A10/A7SS have a "white metal " crankshaft bush?
Mine certainly came with the Vandervell composite steel bush with a bronze-ish sleeve that might once have been flash white metalled?
If this were so and rematalling services are available, would it not be easier to have the engineers re-apply white metal to a good but just past service limit Vandervell composite bush than have turned a nwe lead bronze one or say buying a Kibblewhite one? I say this because white metal will be dead easy to line ream?
Thoughts?
I think the Haynes manual is right.
The bush you have may or may not be original?
I know at least one person who has had a timing side main bush re-metalled successfully.
The reaming is easy for all metals, once you have the correct reamer set up, not that I've personally done it!
You need to check the existing bush is a good interference fit in the case before deciding to re-use it, many aren't, due to the case going oval or getting worn by a the bush fretting/moving, this means a special bush needs to be made, on mine a special steel bush was made with a pinned bronze insert, so it's easy to refuurbish next time (not that I expect that in my lifetime!).
Hope that helps!
