Spur gear for Bosch Universal Classic mixer. Please read the Bowl Assembly Note below, before ordering this part.
We recommend buyingthe spur gear together with a new bowl shellrather than trying to separate your old spur gear from your old bowl to re-use either one.
Also... most old spur gears have slots that facilitate removal of the drive shaft. (In the photo, the slots are the "elongated" parts of the small hole in the middle of the spur gear). But if your old spur gear is different from the one shown here, having NO slots for the drive shaft cross pin to slide through for removal, then you have three options regarding the drive shaft assembly. Option #1 is that you can order a whole newdrive shaft assembly. Option #2 is that you can remove the small cross-pin at the very top of the shaft with the proper size of punch (not real easy to do unless you have a well-equipped shop) and replace it with a newcross pin. Option #3 is to demolish the old spur gear with a large hammer (and maybe chisel), taking eye-protection precautions and being careful not to damage the drive shaft in the process. By demolishing the spur gear in this way, you can then remove the drive shaft for re-use. No matter which approach you take, be sure tools are used on your machine only by persons who are qualified to use them safely.
Bowl Assembly Note: To disassemble the spur gear from the bowl shell requires removal of screws at the top/inside of the bowl column. Over the years Bosch has used more than one type of screw head in this spot. We have no way to know which type of screws your bowl might have, and to remove them you will need a screwdriver with extra long shaft and the proper sort of tip. Removal can be further complicated by corrosion of screw heads and threads from long-term exposure to moisture. For these reasons, we highly recommend buying#UNBA1if you want bowl shell and spur gear pre-assembled and ready for attachment of the shaft drive assembly.
Some very early Bosch mixers had bowls on which the pins holding the splash ring onto the bowl were located outside the rim of the bowl. On this newer replacement bowl the attachment points are inside the rim of the bowl. So if you're replacing one of those very old bowls with this newer bowl, you will also need to order a newer-stylesplash ringandbowl cover.
