Last time, we compared the difference between the lever type Manfrotto 143N and the knob type 244N. But at some point, your Manfrotto 143N Magic Arm (the lever type) might make a weird “crunch” sound and stop working – it won’t tighten OR loosen; you’re stuck somewhere in the middle.
The issue has to do with some ball bearings moving off of their track. So instead of the balls helping the handle rotate, it will now prevent it from rotating.
At first I was hesitant to take this piece of gear apart, but after some intense searching on the internets, I came across a diagram made by someone who had the same problem. Whoever it is that drew the diagram, thank you for sharing your findings!
The video above shows you how to fix this – or you could just use the diagram below if you’re the type that likes to read instructions.
You should have 2 hex wrenches that came with your magic arm, one small one and a large one.
The first screw you want to loosen is the in the handle lever. Use the smaller wrench and turn counter-clockwise. This proved to be extremely difficult and you’ll need a lot of leverage; I’d advise wearing gloves or using a towel around the wrench to protect your hand. You don’t need to remove the screw, just enough to see its head poking out.
CAUTION: Keep the handle lever facing the sky. Any other direction can result in the ball bearings falling out.
Now use the larger wrench and loosen the bottom screw. You have to push into the screw as you loosen it; that should reveal the 3 bearings that sit under the handle.
You don’t have to remove the handle lever, but if you don’t see 3 balls, the missing ones are probably stuck under the handle (in which case, you should remove it and check.)
Once each ball is placed back on its own track, you can put the handle back and screw the bottom first, followed by the top handle screw.
NOTE: Tighten the bottom screw just enough for when the magic arm is in its “release” state.
