Hobart 4346 Meat Grinder Mixer Chopper Extruder Questions & Answers
How to pull auger drive shaft for Hobart 4346 mixer-grinder?
The oil seal is the resistance you feel. take a soft mallet or hammer with a soft drift and gently but firmly tap the stub shaft and it will drive out the oil seal in the hopper direction.The lower skirt of the tapered bearing is what contacts the seal so go slow.Worked for me.
Hobart A200 mixer won't start no power, any suggestions of next steps?
My experience with electrics has mostly been coffee grinders, hand held food blenders and vacuum cleaners but these are the checks I do. Sadly you'll have to open her up again to do these.
Personally I wouldn't use compressed air. Some compressor pressures can be a bit too powerful. I would suggest a vacuum. Stick the foot end of a pair of tights (pantyhose) over the nozzle that way you get suction but you don't lose nuts and screws up into the vacuum.
Opening her up again might reveal a loose wire you missed rebuilding it. That was my issue with a vacuum cleaner I rebuilt.
-Turn the motor by hand using the shaft the blade bolts to. Your feeling for it smoothly and quietly turning. If it's gritty, noisy or your getting tight spots there's dirt or something inside or a bearing is worn out.
-Test for voltage at every point where a wire ends and connects to something else like switches, circuit boards and the motor itself.
-Disconnect the wires to the motor and test for Continuity. Set your Multi meter to Ohms (the little horse shoe symbol) and touch the test probes, one each motor terminal. You should get a very low number somewhere near zero. Most multimeters will beep when you have continuity. If you get an 'L' or 'OL' there's a short or a broken wire.
-I would then do the same test across all the switches on the machine, wires off and test the switch. Just because they move doesn't mean they're working.
These steps usually work for me so give them a try, the multimeter won't hurt the machine.

It sounds like there may be a few potential issues that could be causing the resistance you are experiencing:
- Incorrect installation of the slow speed gear or key - If the slow speed gear or key were installed incorrectly, this could cause increased resistance in certain gears. Double-check the installation of these components to ensure they are properly oriented and positioned.
- Stuck gears - If the gears and key are stuck on the drive shaft, this could cause increased resistance. Try removing the gears and key again, and make sure they are clean and free of any debris before re-installing them.
- Improper alignment of the gears - If the gears are not properly aligned, this could cause increased resistance. Check to make sure the gears are properly seated and aligned with each other.
- Damage to the worm wheel - The freshly chewed up center of the worm wheel could be causing increased resistance. Consider replacing the worm wheel if it appears to be damaged.
Overall, it may be helpful to consult the Hobart service manual for your specific model to ensure all components are installed correctly and to troubleshoot any additional issues that may be causing the resistance.
