Hi everyone:
I am a bit confused as to how to determine which main bearing set to order.
My crankshaft is a "red dot" unit (from an 85 1.9 liter engine).
The mains measure
1) 58.775 mm
2) 54.972 mm
3) not checked yet
4) 40.005 mm
My rod journals all measure right about 54.991mm.
Any help will be appreciated.
Who stocks bearings, btw?
Thanks
Rio

the 1.9 mains are not made at this point by Kolbenschmidt and have not been made for over 2 years 
the bug bearings will work for all but the # 1 thrust bearing for that I have been using a custom made bearing to build the 1.9 engines. The 1.9 cases for the most part need to be align bored. I saw your post on the oil pressure problem so be sure to measure the crank bore in the case and the big ends of the rods this is where your low oil pressure problem is coming from. I stock only align bore bearings for the 1.9 because thats all I use
