Input shaft corrosion

[360DartGT66]

Hey gurus,
I’m putting an OD A833 together with new bearings and all that (kit from Brewer’s). The only snag is that the input shaft is a little corroded.
I’m worried it’ll wear the pilot bushing when in neutral and with the clutch engaged.
What do you guys think I need to do about it? Would it be ok to just turn it down to a smooth finish or do I need to spray it and turn to size?
It measures ok at 3/4”, just a hair over in a few spots (with my Chinese calipers).
I hope the pic is clear enough to determine the grade of corrosion. I can post more pics if requested.

I would polish it with emery cloth and run it.

It really doesn't look that bad. Clean it up good, polish it up and check the size. Stock pilot measures 0.747". A little light pitting is not going to hurt anything. The pilot only spins in the bushing when the clutch is dis-engaged.

Hey Dan, do you recommend any specific kind of grease in the bushing? Thanks for helping us out here on the site.

This is what I use on stock pilot bushing.

Thanks Dan

If it really bothers you that much, use the bearing instead of a bushing. The input shaft will just rest in the inner race and not be spinning like in a bushing.

Oh, it's the actual Brewer!

I think I'll take your advice as gospel, polish it off and use moly lube.

Many thanks!

Oh, and the kit is flawless, of course.

Now that I think about it for the fourth time, of course it only spins when the clutch is disengaged. My bad. Makes it even less of an issue, of course.
