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!

Hello George,
Thank you for your e-mail. The tool you have is our
old 395. Our new tool is the 300 series.
The tool that you require parts for was discontinued many years
ago. Limited parts are available from Dremel.
Inside the tool is a flex coupling and spline driver.
The flex coupling is # 2615294309 and the price is $ 1.25.
This is the hollow plastic sleeve about 1" long with grooves on
the inside, that goes between the motor shaft and the output shaft.
The spline driver is # 2615294308 for $
1.00.
Spline driver sits on the direct end of the motor shaft. The flex
coupling sits over the spline driver. Spline driver is about 1/4", hard plastic
with grooves on the outside.
Total shipping for orders under $ 5.00 is $ 2.50. Orders over $
5.00 is $ 4.00. There could be a tax charge
depending
on which state you live
in.
