This is a 6 Qt. made by Kitchen Aid Stand Up mixer 575. watts with 6 qt. bowl. A powerful machine. But not geared to crush Almonds. After about 2 quarts of Almond crushing to make Almond butter I heard the machine thumbing inside and turned it off immediately. Mind you, I am a 60 year old man with Maintenance Mechanic, and Machinist skills. If you listen to my instructions which aren't that hard you can do this. REMOVE THE POWER CHORD BEFORE CONTINUING. First you have to find the screws that hold the top half of the machine together. They are under the silver Kitchen Aid Stainless Steel 5/8th Band that runs around the middle of the machine. On the back of the machine is a small machine screw that when taken out removes the band. Remove the band carefully as not to bend it because it has to go back on looking pretty. Comes off easy. You will then see 4 longer 3/4 inch screws around the middle of the machine head. When you remove these screws the top half of the machine head will lift up. The top half of the machine head lifts off very easy. Throw all your screws into the top so you don't mis place them. You will see a Motor some gears on the side and a shaft that comes from the motor going into a Cast Aluminum Casing with another 4 screws 3/4 exactly the same size as the ones you took from around the top mixer casing. This is easy cause you don't have allot of different size screws only the one small one that screws on the back of the band. After these four screws are removed, again lift up the top half of the casing but this time it will be full with gear grease. Put the casing aside and using paper towels wife a little of the gear grease off the top gear. In order to turn the gear you must use the side drive gear or look around the gear you will notice in some of the gear slots will be shinny and worn. This is the Bevel Gear. There is a C locking shaft cliff that keeps the gear locked in. You must have a multiple C clip remover pliers that has different size C clips for the holes in the clip must be spread apart in order to remove the clip all the way up the shaft. NOTE:; DO NOT USE A PLYERS TO TRY AND PRY THIS CLIP OFF IT IS STRANG AND YOU MAY MAR THE STAINLESS STEEL GEAR SHAFT. You must use the gear C clip remover, I found one moderately prized for 25 dollars at the Home Depot or any large chain hard ware stores will have it. After the C clip is removed, slide the gear evenly up. If it's stuck that's only because of grease unless you mar the shaft by not listening to me. I also replace the Top Hum Bevel gear which is in the top half of the hub. Parts select has a Diagram that shows you the parts and where they are. When putting on the Bevel Gear over the shaft be sure to lower it evenly and guide it onto the worm gear. There is a small pin that sticks out in the middle of the gear make sure this lines up when setting the gear into the worm gear. The Top Bevel Gear, falls right out and you can use your figures to pull this one out and put the new one in. If you replace the Bevel gear my experience as a mechanics is to always replaces the adjacent gear as well, both will be worn. attach the C cliff the same what as taking it off except opposite. Pull the tow clip holes apart and slide it down to the shaft groove for the clip. Put everything back the way you took it off. One NOTE;.. DO NOT DO TOUGHT THE SIDE DRIVE GEAR IT IS SET IN WITH BRASE LOCKING SHIMS AND HAVE TO BE SET A CERTAIN WAY TO CLOSE. When closing make sure the Top Hub is in line with these brace shims. After screwing the hub back down do not over tighten, just snug it tight. Be sure to buy axle gear grade and replace any grease removed, this chamber must be loaded with grease. There is never too much only too little as you will wear the gears down without the proper amount. DO NOT TOUCH ANY THING THAT DOES NEED TO BE TOUCHED LIKE THE MOTOR OR DRIVE SHAFTS OR SIDE MAIN GEAR…
