Shaft does not rotate motor workink - Bamix De Luxe Hand Mixer

It sounds like there may be a few potential issues that could be causing the resistance you are experiencing:

1. 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.
2. 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.
3. 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.
4. 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.

check motor gear for slippage on shaft

There can be two reasons for a Kenwood Chef to run but not turn the beaters. The most likely one is that the Drive belt has broken.

Or

You have strained the beaters and you have sheared the shear pin in the drive shaft. It is there to save you damaging the motor and gearbox.

Take a look where the agitator pin engages with the dough hook.
Either the agitator pin (sticks out from the agitator shaft) is worn out or the groove in the dough hook where the pin should sit has elongated and worn. Either pin replacement is in order or new hook is required...possibly both.

Check everything you have done for a mistake, the pin through the planetary, the pin through the fuse gear and the pin in the main shaft that drives the bevel gear. That's the gear that pinion gear on the fuse gear shaft mates with. After that you are left with a fuse gear fault. I am assuming that the motor is turning at normal speeds and not somehow binding up, no reason why it should as motor stays in one piece during gear changing procedure.

Contact Hobart for a schematic and manual if you lack one. While on line, ask a technician why it gets hot as this is a sign of a bigger problem.

Here is the exploded parts list fr a K45, perhaps it will help you replace the stripped gear inside the gear housing. It is probably the gear which is driven by the motor shaft.:

take off the chrome ring around the rotator. remove the screws that were hiding under it. pull off the rotator and replace the "O" ring on the shaft.

Shaft should be free for rotation that is ok.
Blade will come off with determined force of pull make sure grasp blade with towel to prevent injury to the fingers.

No, do not swap hot and N.

First, verify rotation. As the attachment shaft rotates, it should push the engagement pin into the keeper slot. Looking down on top of the mixer, the planetary should rotate clockwise.

If the unit runs backwards, does it start slow? Can you get it to run either way by giving it a push start before turning on the power? If so, your start switch is not working properly. (Which is my guess) Check your capacitor.

There is mechanical and electronic start switches. (Metal arms and a contact or a little gold rectangular metal can.)
