20 Most Recent Hobart D300 Stand Mixer Questions & Answers


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:

A body shop (automotive) can get rid of the dings, but re-tinning is the trick.

You may consider purchasing a bowl. For example, I could get you a new 80qt bowl for under $500, and a 20qt for under $150.

What is your location? If I can help, let me know.

It doesn't really matter which wire goes to L1 L2 or L3. All that can happen is it will run in the wrong direction. If it does just interchange any 2 of the L1 to L3 connections and this will reverse the motor.

Hi,I'm a hobart tech and repair these mixer's often.If you see oil in the drip cup then the center shaft seal in the transmission is worn.If there is oil near the transformer then the motor shaft seal is also bad.Hobart doesnt release their service manuals to the public but if you go to their site www.hobartcorp.com you can register for free and get a parts manual thats helpful.If you need help with the repair let me know,i can step you through it.

Best guess is that the gear for 3rd speed is seized together with it's brass bushing and the center, large transmission shaft. I don't recall which gear is for 3rd, but the transmission has two gears (2nd and 3rd speed) which have brass bushings in them. The brass bushing should spin freely on the center shaft (when in final position - sometimes they pull off the shaft tough, but spin freely when in final position, my opinion is that this is OK), and the gear should spin freely of the brass bushing.
My guess is that the 3rd speed gear, being seized to the center shaft, cannot freely idle on the center shaft, which would result in being stuck in 3rd gear.

Here's what you need to do first. Check and make sure the bottom nut on the agitator shaft or planetary shaft is tight (This is the part that the attachments afix to). NEXT, take off the lid exposing the top area. THEN tighten up the largest nut (TIGHTENING is in reverse! SO - TO tighten turn nut to the LEFT). When the nut is tight, then turn on the mixer in 1st gear. IF you still do not have 1st gear, then turn off unit and THEN loosen (By turning to the right) this nut by a 1/4 turn or so, then turn on mixer again -- check for 1st gear. If after loosening this nut to where there is no resistance at all and you still do not have 1st gear, then you may have a sheared KEY on one of the gears that controls 1st gear! Did you hear anything pop or break before this happened? Let me know.
