Watched the video several times. Once I received the parts, I watched it again to see specific sections. Repair was easy when I knew what to expect. It would help if the video could be in sections, so you would not have to watch the entire beginning in order to see later instructions. Also found the parts manual on line and ordering of parts was very easy and processed correctly by your company. Really appreciated your help.

Steps: disassemble, clean, reassemble with new gear and new grease.

I used paint thinner to clean up and wash the old grease, kerosene would also be acceptable. In my case I used a solvent tank with a pump, since I have one, but it would have worked with solvent in a pan and a solvent brush. Then I let the cleaned parts dry overnight, though compressed air may have worked just as well.

Followed instructions

I removed the 5 screws holding the cover. They were square but you can use a Phillips driver. Then I removed the cover on the transmission. All the gears have a place fairly easy to see where they all fit together. The only thing is there is a clip on the main shaft it will need to removed. If you don't have a clip spreader you'll need 2 screw drivers (flat ones). One to spread open the clip and one to slide up the clip take your time. There are two gears on top of each other. Remove the top gear set aside the bottom gear has a pin through the main shaft just pop it out set aside. Here is where the hammer comes in to play. Tap the shaft lightly while holding the mixer connector underneath. The gear is on the shaft snug. Now you'll have to remove the all the grease and replace with new grease. Install the new gear in reverse order. Then add the new grease. Take you time and clean the gasket on the transmission cover before you install it. Test before you install the cover. If all sounds good install the rest of the parts.

Remove screw on back take metal band from around top of mixer in to black gear box remove 4 screws holding cover on carefully remove gears by hand no tools needed clean all grease and metal shavings out of gears and housing install new gear add new gear bearing grease available at any auto parts store and reassemble very easy takes less than 15 min

It is very easy to get the mixer housing apart by removing the screws. the gears and drive are easy to get at and see after the grease is removed. The drive assembly is held on the shaft with a snap ring that that must have a good set of snap ring pliers to remove. After removing the stripped gear it is just a mater of replacing it with the new one. It is easy to see what has to be done. I would like to thank this site for for the super fast service. Jim
