[6pack] Stuck Main Bearing

[Sally or Dick Taylor]

John---The "half way out" is not a good sign, as it sounds like something in the bearing cap is stuck in the oil feed hole in the block. (This happened to me once, when I tried to use a partial nail with a head to "move" the top bearing around. It managed to find it's way up the oil hole). It might help to lower the crank by loosening up the other bearing caps, but I ended up removing the engine to retrieve the nail/head. A lesson learned.

If you don't think there's a "foreign body" up there, you could try using an old bearing half and the 2 pounder, to persuade the stuck bearing out. Do your best to not scratch the crank.

I'm doing #3 main bearing and started with #4 and the Thrust washers. No
problem with them. But I just can't get the top of #3 past half way around.
It's now stuck. I stopped before I did some damage.
Tried tapping (with an alum. bar). Turning with the crankshaft rotating and
using the oil way and pin as a push. Loosening up #4 and #2 for some slack but
with no luck.  Using Permatex red goop for assembly lube.
Now it's stuck (#3 top half).
What is best to do?
Loosen #1?
Con rods went well. And now in the final stretch.
Please help. Maybe a 2 LB. mallet is in order.
Many thanks
John
Greasy and frustrated.
