Page 128, how many bearings get assembly lube?
 

1. Does bearing shell #1 (closest to the flywheel end)?

2. Does underneath no. 8 bearing also get assembly lube?

Thanks1

All bearings get assembly lube. They will be momentarily totally dry of oil when you start the motor.
The #8 bearing gets lubed by applying it to the nose of the crank before you slide the bearing on. "Underneath no. 8" bearing" is not a bearing surface - the crank spins inside the #8 bearing. (I heard your hand smacking your forehead now so I won't belabor the point.) Some people put a small/thin amount of non-hardening sealant around the #8 bearing - not the orange case sealant.

if it is a bearing, it gets lube

Wanted to be very certain, thanks. If you do put non hardening sealant around the 8 bearing, is there a risk of some coming off in the crankcase?

Is there an o-ring used after the flange bearing before the flywheel? I see there is a circumfrence groove in the crankshaft just before the flywheel seal. (see below)

That is a channel for oil flow - not for an o-ring.

See Figure 3-22 for a fully dressed case.

See text on Page 128 - lube the crankshaft nose, or inside of the number eight bearing prior to assembly.

Don't forget to lube the intermediate shaft bearings either...

OK.

Thanks

That's a good question/concern. I have a perhaps irrational dislike for silicone/RTV for that very reason.
If you put too much, yes, "boogers" may squeeze out, break off and plug the small places in the oil system. You don't want to put it on thick around #8. Think paint or sunscreen lotion thickness, not cake frosting thickness. Does that make sense?

The sealing surfaces on 911 motors are so close that they would almost hold oil without sealant. If your motor hasn't been apart since it left the factory, examine how little sealant there is between the cam carriers and the heads.

There's an o-ring in there. If you want some reassurance, simply put a little Curil-T on there...
