Engine alignment tool
 

Does anyone have prints on an engine alignment tool? I'd like to make one myself if i can. Thanks, Eric.

I'm near Anchor Bay if you want to borrow one to duplicate.

Thanks for the offer lee if i head up that way this winter maybe i can stop by and take some dimensions.

No problem, I'm also in Dearborn everyday.

I just use an old upper shaft, if you have a drive detached just use that as your pattern.

here ya go! :D

that dont look so good online......email me and i'll email you the file i have on it....it prints out good :)

All I've seen have been the drive spline shaft (without the u-joint) to which has been welded an extension rod so you don't get greasy when you slide it in and out. Pretty simple.

I redrew it in cad from the picture wally sent me so if anyone needs it I can email it to them.

ofshore,
Please email me a copy.
Thanks,
Phil

go to your local merc dealer and for about 100 bucks get the real deal. part no. 91-805475A1

Would you be able to cut one out of aluminum? Proably would need it to be hard annodized.

$100???? I got mine for like $60 thru MESCO.

We just made several of those on a CNC lathe out of stainless. Didn't take much time at all.

You might want to check out the ITS alignment tool (840965A1). It can be used for all Bravo's and Alpha's. It uses a slide that inserts into the gimbal bearing that the shaft slides thru. If you leave out the slide and put the shaft in the coupler, the shaft should be centered in the gimbal bearing. If not, you can tell which direction the engine has to go to get it to line up. When you think that it's right, push the slide back into the bearing as a final check. It sure is easier than greasing the end to guess which way the alignment is off.

Anybody?

Cord, I would think you want to hard anodize it just to make sure you never bend or dent it, I'm probably going to have mine hardened and ground.


Maxx, it doesn't say on the print so I was just curious what tolerance did you hold? I've never used one so I wasn't sure how much clearance was built in. Thanks.

That ITS unit sounds real interesting, using an spline yoke will not do as good a job as a smooth fitted shaft. You cannot read the grease pattern as good.

ofshore, the turning center held it within .0005. However the ones you buy over the counter are within .010. We made them in two pieces; a stainless steel end with an aluminum handle which allows it to break down and fit in an average size tool box. :)

Maxx give me a call when you get a chance. (978) 985-0639. I lost your new number :(

We made a stainless end with an aluminum handle. This way it can be broken do so it will fit easily in a standard toolbox.

Its so cheap at mercstuff.com that its not worth making yourself. They come de magnitized....and he lives in Shelby Township and you can pick it up at his house and avoid shipping etc.....

Well, that depends on if you happen to have a CNC lathe and some extra stainless steel bar-stock hanging around. :p

I'll bet that Maxx's SS/Alum alignment tool comes demaged too!

Nice idea with the 2 piece tool.

Yeah, it's kinda hard to beat my price, the owner of the company i work for is pretty good about letting people use extra stock to make up parts for their own use as long as it doesn't interfere with work.

Can I have a copy too.

Bet you didn't know that you'd get this much interest :)
I'd love a copy...

will this tool work aligning a Velvet 72c V DRIVE to an arneson ? I have a 36 to 40 in. drive shaft with universals on each end. Also FALCON who and what is ITS. you refer to for an alignment tool #840965A1 ??? thanks andrewmasonsr

andrewmasonsr,

I think this thread is about the alignment tool used for standard, transom mounted Bravo/engine installs, not internal engine drivelines and transmissions. I should have clarified that the "ITS" is a Mercruiser "Integrated Transom" version of the Bravo, which still needs an alignment tool similar to the Bravo. The number I referred to is a Mercruiser part number.

The ITS has additional setback built into a Bravo transom assembly so the tool I referred to is longer, but uses a slide for the part that goes into the gimbal bearing, so it can be used on the standard Bravo, as well as the ITS. The slide also makes it easier to visually adjust the alignment because you can remove it, allowing clearance between the shaft and the gimbal bearing with end of the tool inserted into the engine coupler. By looking at the gap between the shaft and the bearing, you can tell which direction the front of the engine has to move to be in alignment.

By the way, you can also check if the Bravo/engine is close to alignment without the tool. Use a digital level and check the transom angle, note the measurement or "zero" the protractor. Now put the tool on the crank damper, note the measurement. The engine should be 13 degrees different, regardless of transom/bottom angle.

To properly setup an internal driveline you need to get the driveline mounting flanges parallel. You can do this by using a digital level on each to get the same angle, then make sure the engine is square to the transom by measuring the engine on both sides to the transom or just keep the engine parallel, fore/aft, with the mounting stringer (assuming that the stringer is square with the transom).

Hope this helps,
Happy Holidays to all!

Hey, I would like a copy of the deminsions, I just replaced the motor and would make one on my lathe if i had the deminsions. Thanks in advance.
