prop shaft

[redhead78]

Hello, people.... Today I got my new prop shaft to the yard slid on the pack nut and proceeded to push the shaft thru fom inside, it was reall tight, I backed it out, did the regular dazed and confused act for a while. I asked around a little at the marina got a lot of ya ya ya. Did something else for awhile, then figured what the fu*k am I doing,,I put a little grease on the thing and shoved it in, does this sound dirty, anyhow, it was tight but then its suposed to be right? I guess it will wear in..any ideas. Red

What type of shaft log/gland are you using? If it's a packed gland was the packing still in place?

Sounds odd, how about some pics?

Its new also, the packing is in the nut, I just slid it on the shaft, its an inch away from the shaft log. I should tell you I am repowering and I have to have the shaft in b-4 the engine, so I just slid the pack nut on as I can't later.It just seemed tight, I am probably overthinking the whole thing, it will more than likly wear in. I am going to drop in the engine next week and after alignment and exact placement, and securing the engine I will screw the packing nut on.

Probably the packing in the stuffing box was the problem since you didn't remove it. Does it move freely now?

Jim did you see the pics, the stuffing nut is loose on the shaft, 10" away from the gland. It really isn't even a factor. When I'm ready I am going to tighten just hand tight. The shaft turns with no grind or anything its just tight. There is another 36" of shaft after it goes into the stern tube, it then passes under the small rear cabin. Red

If you can turn the shaft easily with one hand, either at the prop end or the flange end, you should be fine. If you can't do this, then you may have a problem.

The shaft shouldn't really be binding at all and turn relatively easily without the packing gland on it. Even with the gland nut tight, you should be able to turn the shaft with one hand, albeit a little more force.

I can turn it with one hand, though its not real easy...no packing nut yet, everything is new and straight...Red

Saw the pics. Packing could still be causing friction even with the packing nut backed off, especially if you knicked off a small piece inserting the shaft and its jammed somewhere. Shouldn't be too hard to rotate. If you can't turn it with one hand without much effort, something isn't right. Was it tight going in at the gland or at the bearing?
