jcampbell, the Volvo Penta PDSs will not be threaded..... that was the point in my telling about the Eaton, Glastron, Donzi, Holman Moody..... some of them were threaded, but none of the OEM Volvo Penta to my knowledge....., unless some of the very early ones were.
As for the bearing/PDS..... the bearing stops against a shoulder on the PDS! It is retained via the small snap ring that you can see from AFT.
So it has NO choice but to come out with the PDS........ unless like the one gentleman (aka 1stboat), who's PDS bearing had disintegrated.
He is still working on removing the outer race from within the bore of his Flywheel Cover!
His inner race came out with the shaft!
What was left of the balls and ball cage...... who knows where they went!
Not sure if he recovered all of them!
We need to get in the habbit of storing our drives fully down and straight forward. This prolongs the life of the drive shaft bellows, and reduces the likelyhood of premature failure, of which eventually leads to the issues that make this PDS so difficult to remove! That, and just plain routine replacement of these bellows and greasing of the PDS bearing(s).
The guys with the V-8's often suffer much worse damage when these go while up on plane, and making a turn.
These guys end up with a flywheel cover with no bellows snout!
The PDS takes out the universal shaft.
The universal shaft wobbles at high speed, and the entire assembly takes out the aft end of the flywheel cover.
Worst case, it also takes out the front of the transmission.
I know this, because I have repaired these for people!
Engine comes out, drive off, drive repair, new/used F/C, new PDS/bearings/seals, engine back in......
Be still for a moment, and you can hear the sound of this;
Ca Ching! $$$$$$$$$
Yeah, that sound!
All because of routine maintenace that became deferred!
