Hobart AE200 - Speed not increasing when gears changed
Hi - I recently replaced plastic (fibreglass?) cog and when I put it back together it no longer changes gear. I can change the gears but the speed doesn't increase.
One 'small' thing to note is that I have a washer left that I couldn't find where it should go.
Needless to say I did it without a manual as the manuals appear to be like goldust!!!
Can anyone point me in the right direction please?

Dear anonymous When you say you can't get 2nd gear in I assume you took out to replace grease and now you are having issues with putting it all back together. With that in mind let me tell you what you may have done. Looking at the diagram of gears and shafts side by side (found on Internet under a200 manual) you need to find the older model a200 manual. Inside the shifting yoke is a divers key and that has to fit inside the yoke then carefully put back on the shaft while depressing that inner shaft spring I think you have left this out or out of place this keeping it from going back together and your getting 2nd gear on
It's not oil in the A200, it's #2 weight grease. Although when it gets old enough it can break down far enough to basically become oil (either that or someone put oil in it previously). There are a number of answers written on fixya.com explaining how to disassemble the transmission and change the grease. Fill with 36 ounces #2 grease. FYI : disassembling the transmission and changing the grease is a very messy task and one can VERY easily reassemble the transmission incorrectly, so consider bringing the mixer to Hobart to have the job done.
The problem you are describing if I follow right I take the grease hole plugs out take the two spanner nuts off the man shaft and the driven shaft stick gear puller jaws into grease hole and put the gear puller onthe center saft and gently raise the top case.
sometimes you read of other problems and solutions and it puts you at the edge of your seat. in this case of changing the worm gear on the A200F was cake. when you drop the lower end (3/4 acorn and jam nut), pull out yoke (speed select handle) the center transmision shaft and gears pull right out.worm gear easy to change at this point. if you can change a motor bearing, then you can do this job. Note: change seals and bearings as needed,check all gears,keys and spacers for wear and if you go the mile take gears off drive gears, these are the 2 smaller trans shafts put in lath if you have accsess to one if not roll shafts on flat surface to see that shafts have no bends in them. Also remember when you put the bottom back do not over tighten the jam nut,hold and lock acorn nut, should spin free and have about .016 to .030 movement up or down. Lay out all part on cardboard the way they came out. should go back together easy.
I just took a look at the www.hobartcorp.com web site and found a lot of parts lists. I did't find the AE200, but there were several listings for A200. You can ask Hobart if the A200 and the AE200 are the same on the inside.
This is common there is a key on the shifter shaft and when you removed it the key came out and is floating in the grease in the tranny ready to destory the gears. That are no longer available at Hobart. if you want the shifter /switch plate off, remove the pin in shifter and the handle thats all. Hobart has a special puller I have two of them but you can use a H type puller to get to the pull threaded holes Mixer should be upside down on head to repair trans.
