    Lost the blade assembly in a failed attempt to “bump start” the stuck shaft, now having trouble accessing the screw to replace said blade. Any advice would be welcome, thanks for your time.

    Carefully, is the best way.

     

    I have a very severe lack of understanding of what you are trying to do.

    So our immersion blender will turn it’s motor but not its Blade.  Having had this issue before with a Waring model I tried to manually turn the blade to see if I could start it moving again. Had no luck turning it but I did manage to frag the blade. Need to replace said Blade, but without being able to turn the shaft that simple project is very difficult.

    What? You contradicted yourself.

    You said the motor will turn but the shaft won’t? Is the shaft seperate? Is it like a right handed gear motor or something?

    Yes, motor runs but shaft doesn’t. They are connected, as this is a very large immersion blender from Dynamic.  There is a lot of whirring noises made but nothing is happening on the blade end.

    Okay, so lets just clear something up.

     

    When you say its “running” you mean its humming, not that its moving, like actually running but its turned on and responding to power and trying to move but its actually not moving?

    Correct

    Fantastic, is something jammed, holding the gear in place? Otherwise, if you are able to, you might just be able to put a wrench on the shaft and turn it opposite to the way its trying to turn, that might make it so its not jammed anymore but you will have to fix the jam somehow, could be the gears got mashes and it won’t turn or a screw fell into the back of the armature and jammed it, many possibilities here.

     

    Are you a service tech or the guy using the machine?

    I am just the user as a Sous Chef at the restaurant. I was not present when the machine failed, as far as I know there was no catastrophic event, it just failed to engage when we tried to start it last week. The machine is used only once or twice a week.  The shaft has no bolt end to easily attach to, my thought is to try a handheld drill to grasp the end and spin it in reverse a bit.

    OkayOkay, but how is the motor jammed then? If the motor is jammed without anything having gone wrong with it then its probably not a jam, could be the windings are shot and its not able to spin. You can try the drill but that machine has a lot more torque then your drill does, when the chefs I work with get their stuff jammed, I grap 2 or 6 foot pipe wrenches and grap the end of the attachment and just tweak it backwards until the jam clears.

    Then i slap them over the fingers to prove my point

     

    Are you able to take the machine apart? Do you have any tools? Mechanical skills, electrical knowledge?

     

    I would open the machine and see whats going on before doing anything, unless you KNOW something got jammed int he blender and couild have jammed the shaft of something is currently stuck, then it might be internal and you might just make it worse by trying to unjam it without looking at it first.

    I usually use something with a lot of tourqe to clear a jam like this, but this unit gives me nothing attach a tool to except the blade. And while it needed replacing anyway, I probably  shouldn’t risk breaking the new one.

     

    I have decent mechanical and electrical experience, but taking this apart and finding worn bushings and gears or significant wear on the motor brushes would only leave me to have to hand the machine to our repair guy in pieces. Might be best if I send it out now, before putting more time and/or damage into it.

     

    I will see if I can find something to attach to the end of the shaft and use my longest wrench with an extension bar and try some moves to get it to shift. Then I’ll hand it to experts like yourself. 

     

    Thank you very much for your patience in sharing your expertise.

    I assume your talking about a Waring Stick blender.Which model have you got and trying to start it plugged in can cost you body parts. Also need to know shaft length.

       Most problems on these are brushes, switch, and on rare occasions a bearing.

    Waring can be difficult if not use to it. In order to remove the stick from the mtor head your will need safety torques. Torque bits with the hole in the middle. And if im not mistaken Waring also sells a special tool to help remove blade. Hope that helps some.

    Actually the Waring is what I am familiar with, the stick blender I am currently having issues with is a Dynamic SMX600E with a 21″ shaft. And perhaps I just lack an attachment to affix to the end of the shaft and turn it because it’s French.  And I am not trying to turn it while it is on, just free it first.

    Bump start was a bad choice of words, but bump free doesn’t have quite the same ring to it.

    At least it isn’t the big one on wheels. It is a direct drive unit with a hoop handle. and the disassembly is a bit difficult. Recommend you sent it out, as reassembly and parts inspection is even worst. Even replacing the drive coupling in the head is a pain..

    No worries, thanks for replying.

     

    If you don’t have parts and won get them to replace them yourself, I would sent it out, I agree with you on that.

     

    Best of luck.

    These guys pretty much covered it.  Here’s my two cents…

     

    What’s happened to your immersion blender is food stuff, moisture, acids and such have gotten past the shaft seal above the blade and into the wand housing.  So with all that in there, it’s trapped and wreak havoc on the shaft bearings.  So…they’re seized.

     

    We get those blenders brought into our shop maybe once a month.  All brands…and they’re all put together differently.  They’re a real pain to disassemble and repair.  Additionally, sometimes it’s best to just replace the entire wand section altogether.  The moisture and acids destroys not only the bearings, but eventually the aluminum wand housing as well.

    Sorry to hear your unit is having issues. Have you taken time to access the parts town breakdown/parts manual? it is very helpful and gives you a breakdown of the unit. the sprocket could be jammed up or broken.

    Just as a coda to this month long issue; the Dynamic stick blender is back from the shop in pieces as the boss decided against the $700 charge for a new motor. Thanks to everyone who helped me out especially Olivero and Fix Bear, have a great New Year.
