Hey, all. I initially installed a 833OD transmission into my /6 Demon and had to take it out after groaning and rumbling in all gears but 3rd(direct drive). Turned out to be a very worn input bearing that had worn the mainshaft also. I Had the input bearing replaced and researched a needle bearing that would work and fixed the. 15K miles later and the tranny is still going strong (Daily driver).

No issues with the transmission in the almost 2 years I've been daily driving the car.. 3 fluid changes (Lucas gear oil 75w80) and no metal either... Keep'n on, keep'n on... :) See y'all out there on the road this summer. Ronnie

Nice to see a good fix for this, as I have one mainshaft with a galled nose that could use this to put together one more box.

Just out of curiousity, is there some data on what loads the bearing can take? Daily driving probably provides mostly a constant load on bearing and some intermittent impact during shifts, but since I've built my engines for max torque to move the heavier body around I'd be concerned on how this setup might take the load from a spirited clutch dumping episode and the hard shifts after that...

This should be added to the 4 speed article or set up as a sticky.

:)

It would be nice if these photos could be put up again, possibly using Postimage.

Also, I don't think we're talking about the 'input bearing' here, that would be the big bearing around the input shaft. Rather, this is the bunch of rollers which make up the bearing inside the input shaft for the nose of the mainshaft.

I have a couple of A833s which I believe have this problem and I'd love to see the fix.

And can we also please have the bearing part number?

I wish there was more support for the 833 o/d.

Brewer's and Passon's both rebuild and sell parts for the OD.

Thanks Dennis. Now, if were an affordable kit to convert the o/d version to a four speed - I believe OEM parts to do this don't exist. I have 4 o/d versions, all pretty crusty with miles. At least I can rebuild them now.

Just as cheap to buy a 1100 buck refurbished 833 box, by the time you get the correct parts together (mainshaft gears - $600+, matching countershaft cluster $$, matching input shaft $$)...
and a rebuild kit with new synchros and gaskets.... that's why the T-5 was the upgrade, at least there you can swap some gearing for better ratios and they are still available...

There were shaft diameter & spline differences IIRC, they would have to be "conversion gears" to turn an OD into a conventional 4spd, so, yeah.......unless You want a project & the satisfaction of doing it, there are reputable builders that will save You time and really expense if You look at it.............

I know a kit would be expensive but I'm sure they'd show up at swap meets. A decent Chinesium gearset should be fine for a slant six. I know, not likely to happen. I find the o/d 833 fairly often in self service salvage yards.
