Thanks! That sounds like about the difference in preload from when I did my car steering gear. I remember the sector shaft preload being about 13 inch/oz for used bearings, but I sure with I had the actual spec for this larger gearbox. When I got the rig, one of the first things I did was tighten the steering box, the input shaft had up and down play til I tightened it enough to remove that. I think it was sloppy enough to never sit in one spot long enough to brinnel a bearing :-D

The other thing I'd like to find is the sector shaft seal, the shaft is 7/8" in diameter and the old one is leaking. Pitman shaft is dry, so I'll go ahead and leave r be. But I'd like to seal up that input, then complete my Craigslist overhaul with a coat of safety black Rust-O-Leum enamel.

It'd be nice to find a part number, but I guess I can also just measure ID, OD, and thickness and match it up that way.
