Next up I am considering taking off all the things that roll underneath and checking the bushings/ bearings since i am there. Is that hard to do? The 62,63,64,65 (spring pin and set screws etc.. look possibly hard to put back together?).

Removing the feed roller bushings is easy?
Challenge is that you have to remove the sprockets/chain that connect everything to gear box.
Bolt #65 holds the plate on the head casting that supports the bushing/roller. #62/63 is used to set the height of rollers relative to the table and is something you will probably be adjusting after reassembly. Adjustment is in the manual.
Spring #60 is best removed from top. Remove Allen screw #138 from top to reach the sprin. Also clean out the oiling channel. It accumulates dust, and can get impacted to point that oil won’t flow down to bushing. You want to at least remove the top Allen screw to release the pressure on the feed roller bushings before removal. The spring will come out top or bottom.
If you put (2) 2×4 on the table, and lower the head till it just touches, the rollers are supported and removing the feed roller hardware is ‘piece of cake’.

Not fan of this bushing design? Thanks to heavy spring pressure on feed rollers, It is the one part that I needed to replace on all 5 planers I have rebuilt over the years. IME – Grizzly has been cheapest place to get new bushings (P1021153) and they always been in stock? The Grizzly bushing fit my; Delta, Powermatic, Jet, and a General planers.

Rebuilt a Powermatic PM15, and it was worn so bad the metal out feed roller was rubbing on the gear box casting. The bushing opening was elongated by ~1/4”. Here is a pic:

The out feed roller had excessive wear in the bearing area and it needed replacing also. PM uses an all metal out feed roller (like Grizzly G1021), unlike the Delta which is rubber covered. When I tore it down and saw the bushing/shaft wear, was amazed that the tool was actually in service when I bought it. Just proves these 15” planers are hard to kill.

The manual recommends a weekly task of adding a couple drops of oil to top of machine, to keep those bushings and feed rollers lubed. IMHO- if tool is only used occasionally, suggest you should put 2-3 drops of oil on those bushings every work session. :-)

If decide to fix the damaged out feed roller rubber, there are two paths: Can still buy OEM replacement part 1349339, or if the shaft is not worn at bearings – can get the existing one re-covered. If can find a local place that repairs commercial printer rollers, they can replace rubber. If not, have seen posts that Western Roller will do the work.

Last but not least for anyone reading this post thinking they can replace an all metal out feed roller with Delta rubber coated version:
It might or might not fit!
Based on my rebuilds, it appears there are 3 different 15” planer mfg, with very slight differences between them (mostly in head/gear box casting). One difference is the length of the feed roller shafts. The Delta OEM unit is ~10mm to short for some clone units. Grizzly recently made the clone planer parts hunt even more interesting; they now sell rubber out feed roller upgrades for the Taiwan made G1021 (Delta 22-680 3HP clone). In past the only one available was for the Chinese made G0453.
Be very interested if anyone buys the new Grizzly T30533 part for a Delta, and it fits. The part is ~$45 less than Delta OEM. :-0)

Best Luck.
