Restoring a 1951 Kenwood “Chef” Electric Food Mixer – Part 2

  1. I like your work very much I am rebuilding A 700D and what a mess looks like it may have garage grade grease in it ? the pc board you made for earlier models is a fantastic idea !!are the motors ever grease or oil free due to poor top rubber cap seal leaking from above?
    Thanks for the words and pics was having trouble even getting the top cover off before finding your info many thanks mark

  2. Thanks for the comment.
    I think on these early models that once that old grease breaks down, the oil will inevitably find its way into the motor compartment. I haven’t yet written the final part of this project blog, but when I put the machine back together I used CRC NSF H1 Synthetic Food Grade Grease, which is a transparent silica based grease. This is supposed to have good stability, so I’m hoping it will last a while.

  3. In your photo in which you show the field coil positioned back into the bottom end-bell, I notice that the bearing has no fibre washer surrounding it (as does the top end) for lubrication. Mine is also missing an oil soaked felt washer here and I am wondering if there was ever one there. The service manual suggests both bearings should have one…

    1. They are actually there in the ends – held in place by the metal tabs which you can see around the opening. They are not easy to remove, so I just cleaned them in place with solvent and put a few drops of oil back on them.

      I still haven’t actually seen the original service manual – would you be able to email me a copy by any chance?

  4. Sorry, I don’t know of any. I think a lot of people just replace the original parts in place and don’t bother making a PCB (there are component kits on eBay). I made my own PCB for fun, and because it keeps things neat and tidy.

  5. Hi Harvey, many thanks for the reply.
    Looking for your blog on glossy paper do you still have the image you Created for the board.
    Did you have any look obtains a service manual.

    Many thanks

    1. I mentioned how I print the circuit boards in the “Spindicator MkII” post. In short, I print the design onto Canon glossy photo paper (which I found to work best), and iron them on to the copper board with plenty of heat and pressure. You really have to lay out your own board to reflect how you want to wire the mixer, and to match the lead spacing of particular components you have. I made my boards 4.8 x 4.5 cm, with a cut-out at the front to allow the mains power cord. I’m sorry, but that’s about the best help I can offer. There is a lot of stuff on the net about making your own boards that you can look up. Enjoy your project.
