Drive Alignment Tool for XRs
 
What is the P/N for the alignment tool for XRs?
Is it different than the standard Bravo tool?
Where is the best, translated cheapest place to get one?
Has anyone had them made for sale?

Thanks
Shawn

hmmmm......i would think its the same as the bravo tool. Only because you can install the x series drives inplace of a standard bravo.......just being a bearing change from what i understand.......maybe just have to machine the bravo tool for the new bearing size now that i think about it???

I looked up 91-805475A 1 for the standard transom and 91-840965A 1 for the integrated transom models.

The X style gimble bearing has a larger ID for the larger input shaft on the X drives. I forget how much bigger, but i thought it was like .050 or somehting???

anyway the standard bravo alignment tool will fit through the gimble bearing, but there will be a little play in it (.050 or so) due to the larger ID of the bearing.

I didn't hear of a new one that came out. maybe Merc doesn't think that .025 slop (.050 divided by 2) would be cruicial in aligning a motor ?

The bearing ID for XZ/XR bravos is the same as std. B1 drives. The width of the XR/XZ bearing is slightly different, but the same alignment tool works for both.

ah so its wider?? more support??? may be a nice upgrade for a standard bravo one if the bearing needs to be replaced :D

If you are purchasing an alignment tool, get the one for the ITS. It can be used for all Bravo's and it is easier to use.

I think all of the newer Bravo transoms now use the new shorter bearing. Someone correct me if I am wrong, but I believe you can tell if it's the shorter bearing because it has a red paint dot on it. I will look closer at one tomorrow and get back to the thread if I am wrong.

it does have a red dot.

and it is a shorter bearing....not larger ID like i thought earlier. they say it is shorter to give clearence for the larger u-joints on the X series.

What Falcon said. Serial # 0M and up all come with the new bearing.

The inside diameter of the bearing is larger on the XR than the B1. Thus this bearing will allow the larger diameter XR to clear as well as the smaller diameter B1.

If the tool has the same diameter as the B1, then there will be clearance around the bearing and not a snug fit. If there is clearance, how do you know if you have proper alignment?

Does the tool for the ITS only fit the XR? Will it fir the "old" style coupler? I do not have the ones with a "snout" on it.

Thanks
Shawn

The bearings have the SAME id, the differance is the newer bearing (red dot) is not as wide on 1 side

Re: Drive Alignment Tool for XRs
 
The ITS alignment tool will fit either style coupler and any version Bravo transom assembly. It has a "slide" that fits over the main shaft and into the gimbal bearing. This allows you to pull the slide back and see a gap between the main bar and the bearing. This gap will show which direction the engine has to go for alignment. No "guessing" with grease. The slide also allows it to be used with the ITS setback or standard Bravo's.

I will also repeat what MBAM and others have said, the bearing ID is the same on any Bravo transom, just the length is different on the red dot side.
