IMCO Extreme to BMAX conversion question
 

So we've got the BMAX's in - they use a larger U-joint than the IMCO's.

What we thought was a simple process of changing the input shaft (for the extension boxes) isn't gonna happen.

The U-Joint on the BMAX's are larger.

So - Does anyone know of a U-Joint that will work? Should I get a machinist to modify the shafts?

Or just bite the bullet and call IMCO and order new shafts that will fit the BMAX's?

Thanks!!

order the new shafts thats what i did,do you want to sale the imcos

I ordered the Shafts from IMCO also...I had extention boxes too, so those new shafts were pricey$$$

Re: IMCO Extreme to BMAX conversion question
 

I have heard of machining a set of lager caps to fit over the smaller ones. I didnt like the idea then and still dont. But that is up to you, just an idea.
I would recommend buying new input shafts.

Do the imco shafts fit bravo drives or imco only?

Re: IMCO Extreme to BMAX conversion question
 

Originally the Imco shafts were setup for the small units that are found standard Bravos. When the XR/XZ's came out they made one to fit that. Now Merc has metric input shafts and Imco is looking at that issue, but I dont think they have a product for it yet. It has been a while since I discussed that issue with them.
I am not familiar with the Bmax input shaft ujoints. I would assume they are the XR size? But you know what assuming does. A call to Imco would verify.. Talk to Rick.

In the automotive world they make U joints large on one end and small on the other. Most good driveshaft shop carry them. Mite be a quick fix if you bring in both sizes for them to measure.
