Hobart N50 Service Manual
Ebay sometimes has used hobart manuals. maybe check Amazon.com?
There is no other source for hobart manuals other than the internet.
I just picked up a used Hobart N-50 Mixer. Serial
Before doing anything else, make sure the hole in the whisk is perfectly clean by taking a cotton swab dipped in isopropyl alcohol and removing any remaining residue. It does not take very much residue to make fitting difficult.
If that does not work, the hole can carefully be enlarged using a round file or sandpaper wrapped around a pencil. Do this a little bit at a time and test fitting. You will want to do the minimum necessary to get the whisk to fit.

Is the planetary still off before the taper pin is in place?
It's a shot in the dark but if everything lines up, I can think of two possibilities:
1. The taper pin in backwards, and
2. The shaft hole in the planetary is out of round.

The gear has not really changed. It is a fail-safe gear designed to break before the motor is damaged by the transmission being jammed.
As to whether it will last, I can't say. I know of no other sources for the gear other than keeping a watch of Ebay.

The frequency is the same in all gears.
disconnect the power and invert the mixer and remove the planetary after driving out the taper pin, then you can access the transmission. It may be a rotor shaft bearing in the motor or no grease on the worm gears.
Nice touch with the video.

Are you still having an issue with your HOBART N50. Let me know and I can walk you through it.
New (old) N50 ML-4749
You should be able to purchase the manual. I know that Hobart abandoned that policy a few years back -- unless they re-instated it. Call Mother Hobart and ask. 937-332-3000
There is a few tricks to these units, it would be tough to convey here. But here goes...
Remove back cover. Loosen 6 or 7 screws around outside of motor windings. Thump the nose of the mixer downward to break the seal. Watch for spacer washers where shafts go into motor case. Remove spring. Remove idler. Remove shifting guide. Remove gear assy. Leave beveled gears in place if possible. Clean. Use Darina II grease. (20 oz) Clean and permatex "seal". Tighten mounting bolts. Adjust set screw at back of planetary. (Double set screw. The first one is to lock the adjustment.) Test in 1st and then 3rd while turning the set screw. You just make it quiet for a proper adjustment.
Good luck -- Mike
How to completely dismantle a Hobart N50 or KitchenAid Model G
If you only want to service the unit and not open the case, you can add grease through the gear shifter plate opening once you remove it. if you have a grease gun with a flex nozzle that's a bonus.
If not it is a messy job. Keep lots of paper towels at hand and use a narrow spatula to get the grease inside. Get as much in as you possibly can.
To remove planetary, with pin removed, spray a bit of wd-40 or other penetrating oil into where the pin came out of let it penetrate for a few minutes. Plan-A Take two screwdrivers and gently try to pry the planetary away from the body of the mixer. Plan-B Add a bit more lubricant to the shaft pin area and install a beater, then try prying with one screwdriver while putting downward pressure on the beater, alternate prying on both sides of planetary. Excessive force at the planetary top can/will crack it as it is a molded piece of metal. If you found this solution helpfull, please rate it. Good luck.
