Shaft, Strut Alignment Video

There is a new video on the CorrectCraftFan channel on YouTube - Inboard Shaft Alignment - 101 featuring the expert instruction of Peter Brainard as presented at the 2010 CorrectCraftFan.com Midwest Reunion.



Look for more instructional videos coming soon.

Thank you,
Keith

Keith,
That's for getting the vid up on site. I know it will help many.

Mark,
A loose coupling on the shaft isn't good. It will fret (wear out material) to the point where it will pound out the set screws as well as the key/keyway. If you think about it some, every revolution the shaft will want to go from one side to the other in the bore of the coupling. Make sure you have a safety collar on the shaft just in case it comes out. How did you end up with the loose fit? Did you get a new shaft and was it smaller than the old?

The proper way to do a new shaft R&R is to get a new coupling half if the fit is off. The coupling will come in on the small side of the bore and then it's bored for the press/shrink fit to the exact diameter of the new shaft.

The ARE double tapers are nice!!

Mark,
The safety collar is a shaft "set collar" that goes on the shaft just forward of the packing gland. (someone will have a picture). It's there just in case the shaft comes out of the coupling. It prevents the prop from hitting the rudder.

When you had the coupling face trued up, did they by chance measure the bore and shaft? Keep a close eye on it and make sure your alignment is good. That will really help.

Great video Pete..

Not a bad idea. I could do that fairly easy. Probably would be a bit more helpful broken out since we can't do chapters in YouTube.

Give me a few days.

You guys can't last 14 minutes??

Dan,
Thanks! Does anyone really look like the "picture" you develop in their mind?? The same is true via the phone. I remember (way back in my single days) talking to a girl for years over the phone and always thinking about wanting to meet her. Well, that day did come and.........

look at the way he handles wood...

oop's

I've got to have Keith lock up this thread!!!

You can do my V drive next, and we'll set it up as a PPV movie for the guys at PN. Just think of all the money you'll make, you can step up to a boat made in 70's possibly even the 80's.

On a bit more serious note, I found with a bit of thinking and C clamps you can move the engine side to side. I haven't tried it on the Excel, but it worked great on my Commander. Once you get everything in place it's just a matter of 1/4 turns and it straightens right up without a bunch of over shoot. Didn't find any tricks to the up and down, I liked the counting turns and doing front and back. Not thinking about it like that is probably why it took a while.

You missed the point, I was just trying to get the free alignment check because of the difficulty. By the way, I looked at the PCM motor mounts a little harder last night and I don't think the C clamp trick would work.
