Thanks for the additional input.

I'm clear on the input shaft length exposure and in fact am using this bearing so I can use an 833 which already had the shaft cut down. For a while there you could pick them up cheaper if the shaft was cut.

Had purchased a bearing already, but then my brother needed one so I gave him mine. He hadn't saved the box for the part number and my filing system failed me. Come to think of it he never paid me for the bearing......
