hi

there is a ring clamp on top of the main worm follower gear on the drive shaft. you might not see it due to the grease.

you need to get one of those weird little pliers with points on them to spread the ring clamp to remove it. Then the gear is just friction fit on the shaft...it's pretty tight. I carefully used a screwdriver to slowly separate the main follower gear from the lower gear and it goes up the shaft....

after a bit you can wiggle the follower gear by hand and it will come up. Then you can see there is a pin holding the drive gear underneath it in place. The pin in my mixer was actually bent (must have been some tough dough).

then you reverse the process to put the gear back on -- except that the top follower gear has to go on the pin in the right orientation or the ring clamp won't fit.

buy your parts from mendingshed.com

hope it helps.

Harry, if you're confident that you can take it apart and repair it yourself, then do the following. Go to www.hobartservice.com website. Register, and when you've been admitted to the site find the discontinued products section on the left hand side of the page, click on it, then select the Food Machines Group, then select Mixers. Make sure that your ML# is covered by the document.Select the file numbered A-200 Parts List F-6728. pdf. Look for the ML#. Once you've selected the document, go to page #9, there you'll find the exploded drawings for the A 200 transmission parts. If you look at the whole document (15 pages), you should be able to see what needs to be taken apart to get at the worm gear.

If you're not sure you can do this...Then don't do it. But if you do, check all bearings, springs and gears for excessive wear and replace as necessary. Hobart techs do this stuff every day. For someone who has not done this kind of rebuilding before, it can be a long and expensive learning curve. Good luck. If you find that this solution has been helpfull to you, please rate it. ricardok45

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.

Harry Ooooooooooo

SOURCE: No power after replacing worm gear in Kitchenaid KSM90 Mixer

Remove the rear cap from the unit. Power comes in from the black wire with the white being common. Hold a voltmeter lead on the white and check for power on the black. Power goes across the bottom of the speed control unit via a buss bar. Check for power on the right side, I think it is a red wire (may be a white one). Power is taken into the motor via that wire, goes thru the windings and the brushes and then out the other brush wire and back to the board. Check for power on the return wire. If it is dead then either the windings in the motor are burned out or one of the brushes is dirty and needs to be cleaned and reseated prpperly [note there is one and only one way the brush goes in!!!! Install it incorrectly and the brush will not touch the commutator.

Try that and see if it runs after cleaning the brushes.
