Help with Bravo XR upper part #2
 

Hello
I need technical assistance with replacing this spare part in a Bravo XR upper housing, part number 2 in the image. Unfortunately, I don’t know the name of the part, but I’m planning to replace it as a preventative measure before it becomes a problem.

I’ll also be replacing bearing number 7.
What is part number 6 and do I need this one too?

There is a newly manufactured aftermarket part available from Bravoshop, but it requires also purchasing and installing their custom-made shaft and bearing.
However, they do offer better-condition used part number 2 for sale, which is what I’m planning to go with.

Has anyone done this before and can offer some guidance?
The part is supposed to be threaded into the housing with thread locker, and I’ve heard it can be a real pain to remove — there’s a risk of damaging the threads.

Any advice would be greatly appreciated.

Thanks

I believe # 2 is the steel tower ? and I think it screws in

Yes you seem to be absolutely right.

But I wonder if it’s just a plain/sleeve bearing on the outside of the tower #6 in the picture, and one needle bearing on the inside #7 in the picture on inside and outside of the steel tower.
If so, you only should have to change the plain/sleeve bearing?

I don’t have the XR right now in front of me so I can’t look at it. It will come with a boat I’m going to by so I need to fix it

6 is the inner race for the driven gear, they make a tool for getting that off,
7 is the clutch shaft bearing, that drives out and in relatively easy

I’ve been into a lot of them and never had the need to replace the tower.

I’ve replaced the internal needle bearings in the driven gears just due to
the fact that that you basically have to destroy them to get ahold of them to remove them once you have a failure( so you can clean out of the contamination……this is if the upper gears weren’t the culprit and requiring replacement.

Then then inner races for these on the outer tower naturally get replaced.

The clutch shaft bearings, (inside the tower)they live a harder life, they’re smaller, their bearing
speed is faster, and when they’re used as l/h rotation, they experience more load.

Luckily, there easy to change

I grenaded a upper end of last season so bad it tore the tower out of the housing............

thanks. I’m going the check every part, maybe it’s just the inner and outer bearings to change. Sounds strange that it should be the tower that is bad.

Yes I saw a video on YouTube where max machine showed a grenaded upper and, good videos.. but didn’t look fun

I’vehad a tower shear off in a std bravo case (which are not the steel tower) but every time on a X case that I’ve dealt with( when a gear tooth breaks off and tries to swim between the drive and the driven gears, this happens
