Should go easily. Is your collar fully loosened?

kahlid74:

The collar is fully loosened.  I got the 3/4" bore 6" diameter pulley on it just fine but the pillow lock bearings are just kind of being a pain in the butt.  I'm also not really pushing it all that far down it because I don't want to put it fully on until I have a test base assembled.  So yeah, still not really going on.

DNA Dan:

It only takes 1/64th or less of an inch to make this an issue. I would take some superfine steel wool and work the rod lenghtwise. Wipe it down with mineral spirits and give it another go. If that doesn't work, use some super fine 4000 grit sandpaper and wetsand the rod lengthwise. Again, wipe with mineral spirits and try again.

Another possibility is the rod is slightly bowed at the point where it gets stuck. Not much you can do but shrink and smooth out the sides.

You could also try freezing the rod and taking a blowtorch to the bearing.

Whatever you do, make sure there isn't any shavings or dust from the rod when you try to press it in. Although small, they will build up and make matters worse with such a tight fit.

That sucks then.  I had to ask, I can't tell you how many times for me it's been something simple like that.  +1 to a light sanding and lube. 

DNA Dan:

Where did you get the shaft from? :dunno Where did you get the pillow block from?

Might be a good idea to take some calipers to the ID and OD to see which one is off, then send the company an email.
