Yep it's like me. When I rebuild the mixers I don't use ordinary products. Example, the lubricant in the gear box. KitchenAid uses a horrible quality product (don't ask me why I guess because it's REALLY cheap) but when I rebuild I use a very high end synthetic EP (Extreme Pressure/High Temperature) GL2 grease that is food safe. Cheap it's not It costs ME $13.00 per application. But, when I am done I give my customers a full year warranty. I don't want grease breakdowns to give me headaches. Because close to 100% of all the mechanical failures I see on them is due to the factory grease. Another thing I do is on the larger "Professional" ones like the 6qt and larger 5qt models my buddy who's a retired machinist/tool and die maker helped me device a way to reinforce the planetary assembly on those machines. (Since about 10% of those failures are the planetary falling apart). So once he's done it's one more thing I never have to worry about. Yeah it costs me a lot extra to drive the pieces over to his house about 40 miles each way (and buy him lunch LOL) but it allows me to sell my product with far more confidence it will last for years to come
