hello to all, I currently have a bravo B1 casing that I would like to install XR gears with yoke assembly XR, I installed pinion seal carrier and retainer nut bravo 1, the problem is that the spanner nut is too small for the yoke assembly it remains trapped inside during assembly.
Has anyone done this upgrade before and can help me out?

Imco used to make a b-1 diameter seal retainer.
ive seen guys cut out a section of their retainer wrench.

yes know what i had a retainer key cut, my other question is can i use the bravo 1pinion seal carrier and retainer nut to do the conversion?

If I get a min I’ll measure some seals and the carriers. See if there is a combination that fits the b1 retainer and xr input shaft

I am pretty sure the Imco retainer is the only solution.

if I look at imco retainer nut or their pinion seal carrier know a copy of bravo satandart no?
