Hobart Food Mixers - Page 7 - Recent Questions, Troubleshooting & Support

The brass nut threads are worn.You have to remove the bowl yolk from the slides to get to the nut.I'm a hobart tech and repair these units often,any questions let me know----Tony.

You are in for an adventure. The first step is to find the N-50 Service Manual online and download it. Trouble shifting speeds is rarely a simple matter of lack of grease. If your mixer shifted before removing the switch plate, then there is a post that shift lever engages which in not being engaged properly. On the other hand, if that is not the problem, the transmission case must be removed. Shifting gears involves moving the tumbler yoke assembly. If you are extremely lucky the yoke's spring has become detached and re-attaching it will be all that is needed. Of course the spring will be in place and you will have to deal with all the grease and investigate the cause. This is a good time to replace the old grease as well.

Contact Hobart. They should have the answer.

If your N-50 is making a grinding noise there is a strong (almost certain) possibility that the cause is more than just needing more grease. The sources of the noise are from the transmission case (front portion of the motor housing) and/or the planetary (where the blade attaches). A search online should turn up the N-50 Service Manual. With luck, it may be that the two adjustments specified in the Service Manual will do the trick Three things come to mind regarding the noise: 1) If simply greasing the planetary does not do the trick, then 2) There are two adjustments to the transmission detailed in the Service Manual. And if that is not the cure 3) The transmission housing will need to be removed to find the source of the grinding. This is where the grease is truly encountered.

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.

That machine is not made to mix dough in 2nd gear!!!

a new shaft to replace the broken one get it from Hobart spares for the model

Weird sound usually means something in the gear box. I found a copy of the manual which includes many exploded drawings; perhaps something in here might help: http://www.bakedeco.com/ebay/pdf/HobartD300.pdf

Goto hobartcorp.com,create a username and then you will be able to find out what your looking for.I know that these mixers used oil when they where new but now changed to grease.Any ? let me know as im a hobart tech a repair these often.

I'm having the same problem cap and all look good but still the motor won't run and the the overload trips the breaker

Does the shaft the motor derives spin freely? Either the motor is being overloaded or the motor is failing.

that is because you are overloading it. the 400 watt is only a medium power. I have a 800 watt stand and i do load it and it takes it. do you have it on an extension cord? are you using the wrong attachment? regards sir jdht
