Building my engine I did a test fit and all was good. So I moved on to the actual build and all went well. Then when I installed the other case half, I rotated the crank and all was good. Tightened the small M8 nuts next to the flywheel and rotated the crank. All was well. Tightened the small nuts next to the split bearing and rotated the crank. NOPE! Crank wouldn’t budge. Loosened those nuts and the crank turned freely. Not sure what the cause is. ❓ I think the split main bearing or the No. 3 bearing is not seated. Okay all you VW engine builders…what’s your take on my situation? Assistance sil vous plait!
Thanks in advance.Allen Caron

I think it’s time to split the case and check the bearings…Check to make sure that all bearing retaining pins are firmly seated also.Early FF TDr on 69 VW pan
Slowly coming back from the ashes...Remembered one thing when I was splitting the case (I did it twice). Each time the middle cam bearing was not in the case but laying on the cam. I’ve taken the cam out and all the cam bearings and will check the serial numbers of each half to be certain I didn’t mismatch the bearing halves. Also will check and remark all the bearings. I’ll report tomorrow after reassembly.

"If one thing matters, everything matters" - from the book The ShackDisassembled the case and found the problem was the No. 4 main bearing (closest to pulley) was not fully seated on the pin. Bearing ended up getting gouged along the pin hole. New bearing tomorrow and a new pulley woodruff key as the old one fits very loose.

"If one thing matters, everything matters" - from the book The ShackFigured it was something similar…
BTW, if you’re having problems holding the split cam bearings in the top half of the case, I’ve found that a bit of old-school STP or Motor Honey works better than assembly lube. Wipe a small amount on the backside of the bearing to hold it onto the journals, then put assembly lube on cam… It’s sticky like honey, and holds the bearing shell in place pretty well…You might already know this, or have another “trick” that works for you, but I thought I’d throw it out there…Early FF TDr on 69 VW pan
Slowly coming back from the ashes...Thanks for the idea. I’ll try it out.
