Kmix hm790 How do I split the case to replace the

A lot would depend on whether this was a hand mixer or a stand mixer, but I guess most likely to be a hand mixer.

All questions on Fixya should have
make model (what it is)

In a hand mixer, you have strained the mechanism and slipped a few teeth on the gears inside. You need to split the case and re-time them.

the head gears are not engaging properly
could be the selector knob or stripped gears
get a quote from an appliance repair shop but if the mixer has a few years on ti then it will probably turn out cheaper to get a new one

Your worm gear is no longer seated and that is more than likely because the housing cover is probably the old style plastic and it has cracked which allows the worm gear to jump up during operation and turn out of sync. The worm gear turns the drive gear that works the planetary gears which in turn drives the beater. If the worm gear is not turning true then of course it is pushing the planetary out of true as it turns, which causes the beater to slam the sides of the bowl. The question is this...does the beater hit the bowl in the same place on the bowl every time? Or does the beater hit the bowl in different places every time? If it hits the same place then it is probably just a planetary gear of which there are four gears involved and it could be any one of them. It it hits a different place every time it is most likely the worm gear and cover. In either case parts will cost between 30 and 50 dollars. and it takes about an hour to fix.

It will be a broken or missing pin through a gear or the planetary or something wrong with the fuse gear. It should be easy enough to find but you will need to split the gearbox cases to check.

At the point of attachment where the hook is attached to the beater shaft, spray hot soapy water from a window spray bottle on the connection. Very hot water is necessary and eventually the water will seep into the locking space and allow you to twist it off. Repeat several times if it fails the first time around.

Hi, it sounds like a broken gear.

Here's how to fix the stuck implement problem:

The implements each have adjustable heights. to adjust the height you need to loosen the bolt at the top with a 14mm spanner. If the bolt was loose when it was being used then it can get too short and not leave enough clearance between the bolt and the machine in order to push up and turn to release the implement. If this happens take the open ended spanner, grasp the implement and rotate the spanner clockwise (when looking up at the machine from below. Once the nut is loose rotate the implement until there is enough clearance to remove it normally.
