241/205 doubler intermediate shaft

I talked to RCV Performance on tuesday, May10th this week. Sean, their production R&D guy said that my shaft is done except for a small issue.
when it went in for it's final heat treat, it "grew" more than he had anticipated, and will not fit in the shift collar any longer.
So, they need to broach it back down to nominal size again and do another heat treat. He told me to call him on Friday(tomorrow)

If it were only that easy

apparently I was mislead...?

That bearing does not exist as far as I know, we've looked plenty. Regardless, if it existed, it would certainly be rated for much less than a factory 205 input, the rollers would be extra small in an extra stressful application.


It does seem easy to use the smaller 10/23/27 spline inputs without changing input bearings/gears and potentially machining housings. We made doublers in the 90's that used the 10/23/27 spline inputs in the 205 and they simply didn't hold up, so we don't use them.

Search around about input conversions about ten years back, we pretty well hashed out the "conversion" bearing. In a nutshell, the load rating was less, the bearing thickness is less and the diameter makes for some goofy stuff when indexing the adapters. Machining the housing is just not that hard.

We also have an adapter system for the 465 that cuts the length down to about 4" and is 32 spline. Works on a 203 with a face drill and a 241 can bolt right on. no better than the 208 system really, just shorter.

Just got news!
Completed Shaft and all samples and shift collar are all on their way back to me. when I get back around the 1st of June we'll get this doubler business finished!
