Greetings, all you thinkers...
I have an apparently immobile center-remains of an intermediate drive shaft bearing which has resisted all my efforts so far to get it to slide up the shaft. I'll skip the gory details of how we got to this point other than to say it must come off if I am to remove the shaft for shortening and checking for straight, redoing the cutlass bearing, and so on. The need for shortening was shooting myself in the foot when I replaced the shaft as we bought it (pitted, scored, and I wanted more length) by making it too long and thus having too much beyond the cutlass bearing, allowing enough movement out there to cause whip in the middle of the 9'+ shaft, and thus the installation of an intermediate bearing. That it didn't have, or, I expect, need one (or the extremely anal surveyor would have commented on it during our sea trial), suggests that shortening it to the minimum possible (along with the newly rebuilt - and thus balanced - Maxprop) will make that feature unneeded. In any event, the picture gallery is the Maxprop - Shaft - Bearing folio in the 2011 refit section of my gallery linked below, if you care to see what's happened so far. I got the setscrews out after long periods of soaking and trying and banging, but all my efforts at getting it to slide up the shaft, so far, have been for naught. That is, except for what I assume must be SOME movement, as, before I thought far enough ahead about the potential for dings, I whacked it with a long, BIG screwdriver (the only suitable - as much as it WASN'T really suitable - driver I had to hand) without protecting the shaft. Looking closely, I see a half-dozen or so closely-spaced nicks which I presume were the screwdriver's fault (well, mine, of course!), and perhaps a quarter-inch of blank space (presumed gained when I quit putting the screwdriver on the shaft!). This leads me to believe that I have, in fact moved it slightly, but no further. Why NOT no further doesn't compute, as there's nothing up the shaft which would have the mass or chops to impede its sliding - and, certainly, it won't move back down the shaft (or, at least, I don't have the access to whack it from the other direction, and its currently immobile condition suggests I'd not be able to move it by hand). I've tried heating it, but I don't have anything which can inject massive amounts of heat quickly, so that's probably the reason it didn't help. I've anti-seized it to death, with no apparent difference, despite my seeing that it appears to run through relatively easily (seep down from up to down angle, setscrew holes filled, then emptying over time). My 10-years internet buddy, recently ex- of this yard, who's faced most of the challenges I have, tells me to cut it off with a cutoff in my angle grinder as he did with his. As I don't want to accidentally involve my shaft, I've not done that, but am approaching the point where I measure the height of the bearing and mark my cutoff wheel to a depth slightly less than that (becoming even more less as the material is worn off in cutting), and have at it. Certainly, cutting off the housing and the race worked adequately. But I'd rather just slide it up. Any other ideas? Thanks, y'all...
