Charles - I'll ask my question a different way. Since I have never seen a new set of rings, are they still the same as what is shown in the drawing, or is it possible that the style of the rings has changed from what is drawn to what I have in my car?
Henry - Yes, the pins are 22mm. You asked about the crank bearing size. I assume this is the four large bearings and not the rod bearings on the crank??
In either case, the surface on the crank of the large bearings measure about 59.43 mm, and the part number of the current bearings is 1803301 (some have "KZ" as part of the number. Possibly Mfg.)
Or do I first have to have the crank turned down to a specific size?
The 6 bearings for the rods measure about 47.42mm and the bearing part number is 1804410 "KZ".
Aa I read through the manual and these entries, I need to ensure the correct sequence of steps. If the bearings are of a specific thickness, then I assume the crank must be turned down to very specific diameter.
As an example. . . Currently my main bearing journals measure 59.43. I see in the parts manual there are bearings for 60mm - 59.0mm in 0.25mm increments. Should I then have mine turned down from 59.43 to 59.25, and then get bearings with the inner diameter of 59.25mm?
Here is one more important point to be aware of. In 1963, this car was shipped back to Stutgart to have a lot of work done by the factory.
The Shop Manual makes mention of a preferred process of swapping out major components such as engine, transmission, etc. I think this was done.
I believe that the block and head are of a newer engine and maybe some of the part numbers are not the same??
I see that none of my current bearings for the crank or rod are in the original parts manual. I also see that the piston is of the 220a style.
So, if I need to start looking for bearings for the crank, should I be looking for the ones with I.D. of 59.25mm? My 220 parts manual shows that part number as 180 033 09 01.
