Question about Dremel Variable - Speed Multipro Rotary Tool 395

1 Answer

Motor works but no drive to shaft.

Hi,
My dremel 396 runs fine(motor) but the shaft(ie the part the chuck hangs off) is not spinning so it's not useable.I can hang on to the shaft with the motor running flat out, there is no drive to the shaft.The shaft lock still works.Any thoughts would be much appreciated.Thank you.

My 15 year old Dremel 395 had the same problem so I took it apart. There is a plastic spline between the motor and the output shaft to the chuck . My plastic spline was split and had many of its teeth sheared off. The shaft lock acts on the output shaft side of this spline, so it was ok. Otherwise everything looked great; bearings ran free & had little play free, brushes ok. To be fair, my Dremel had seen hard use & doesn't owe me anything. No luck so far finding replacement spline parts, which if available should be easy to install. To take apart your tool, just google "Dremel Disassembly". GOOD LUCK!

How do cars with clutches work?


Clutches are useful in devices that have two rotating shafts. In these devices, one of the shafts is typically driven by a motor or pulley, and the other shaft drives another device. In a drill, for instance, one shaft is driven by a motor and the other drives a drill chuck. The clutch connects the two shafts so that they can either be locked together and spin at the same speed, or be decoupled and spin at different speeds.Clutches are useful in devices that have two rotating shafts.

Generator is running perfectly but wont put out any power?


Hello, you will need to Flash the Field. With the generator running, plug a drill motor into one of the 110 volt recepticles. Now for the DANGEROUS part. Pull the trigger on the drill.........now with the other hand..........Quickly spin the chuck. DONT hang on to the chuck. The drill should start to run. ..Your done. If it doesnt work, spin the chuck the other way. This polerizes the stator and will work.

BE CARFULL.

Happy Generating!

Let me know how it goes, Thanks

Motor runs, collet doesn't turn


get a hot glue gun and go to your local hardware store and buy a piece of tubing to fit the collet shaft fill with hot glue and press it on the shaft.

Dremel repair: The motor spins but the tool does not turn.


I use heat shrink and found one that was larger and cut it down to less than an inch. I heated it with a lighter enough to fit the same size over it. and then heated that one enough to slip inside. I did one more so I ended up with 3 of the same heat shrink tubing (pink) and covered over both of the shafts and heated the whole thing so they all sealed and made a connecting shaft. In a pinch it worked well and never had a problem. there is a picture attached.
