A pilot bearing that costs $28 bucks.

Doesn't the 5.9 Magnum cast crank have to be machined to accept the input shaft of the A-833 4-speed?

I know there is a roller pilot bearing sold to use for this conversion as I bought one from Brewers.

If not, I thought you had to trim the input shaft of the transmission approx 1/2 " to fit properly.

I’ve never done an 833 to a magnum, but I am right in the middle of doing a T56 magnum to a 5.9 magnum and it was very straight forward. From the searching Ive done it seems the 833 is a direct bolt on affair.
 
I could be wrong but I think the G3 is the only one that needs to have the input shaft cut down. I know for sure that one does, and I don't remember a Magnum needing that mod, but my memory isn't always the best.

I have a A-833 4-speed on my 408 Magnum Stroker. I didn't need to do any crank modifications, just used the roller pilot bearing you mentioned. But, I seem to recall when talking to Brewers that they mentioned to check the crank to make sure it was drilled deep enough for the input shaft of the 4- speed.

Cheers!!

I've for sure heard of issues where the OD isn't right for the oilite bearing to press in. And it does seem like sometimes if the crank isn't finished for the bearing that it also isn't drill deep enough. But it's more of a feeling than a definite memory. :)

this is very much true for LA engines in that some cranks are drilled for the 4spd input and some are not-- a mistake of not checking you'll only make once...

i don't know if they changed that and all the magnum engines are drilled, but i've yet to find one that wasn't.
