Looks a little tight getting my micrometer inside the FW to measure, we`ll see how it goes.
Iam not saying it is 34mm, just a guess right now, thinking how difficult it was to get that bearing in, when the other engine it almost fell in, in comparison.
Well it is just a silly little millimeter.

I just went through this on a 1985 300D.
I gently used a dremel with 180 grit barrel sander, to clean the crankshaft bore.
The transmission pilot shaft:
#1. Buy a pack of 180 grit sandpaper Body File Sheets = dimensions are 2 3/4in. x 17 1/2in.
#2. Lock it in first gear.
#3. Have an assistant (slow and steady) rotate the output flange.
#4. Work the sand paper (light even stroke/pressure) on the bearing pilot surface like a shoe shine, three revolutions.
#5. Stop, dry wipe the pilot shaft and test fit the bearing.
#6. Note: The bearing should be light contact, not a tight - hard fit.
#7. Repeat steps #3 through #6 as needed.
#8. Lubricate inside the bearing, and the pilot shaft with a light (skin) coat of Wheel bearing Grease.
Triple check the pressure plate, many after market units claim to fit the MB flywheel, when they are actually a few hundredths of an inch to wide = they fail to fully seat = set cockeyed, but can fool a visual inspection.
Always measure the seated height at three or more locations, BEFORE you try installing the transmission.
