How to replace the spline and coupling - Dremel Variable - Speed Multipro Rotary Tool 395

Hi Larry, 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 about $ 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 about $ 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. Here is how to order: Call Dremel Customer Service at 1-800-437-3635 , Monday-Friday from 7 am to 6 pm central time. VISA, MasterCard or Discover to place a Visa, MasterCard or Discover order. To order by mail: Dremel 4915 21st Street Racine, WI 53406 USA 1-800-437-3635 ext. 3636

All functions operate normally except the machine will not agitate.

The agitator is driven by a couple of different methods. The first is the agitator is splined and slips onto the matching splines of the agitator shaft from the transmission. The second is the use of a bell coupling which is splined to the agitator shaft as well and the agitator snaps onto the coupling. If the agitator does not agitate, first remove the agitator and watch the agitator shaft to see if it is working properly. This wil require a small load setting of water and the machine set to run. If the agitator shaft is working properly, it is either the splines on the agitator or the bell coupling that is defective. If the agitator shaft does not work properly, the problem is in the transmission.

To redo the shaft would require a machining tool and that means removing the input shaft, with the bother I would replace with standard parts since you would have to tear it down anyway..... Just a small amount of eccentricity would cause vibration.....

Here's the email from I got from Dremel (in my case the flex coupling broke):

Hope this helps.

This engine has a cam driven water pump. If the gear is sheared/broken it can cause this issue.

Faulty Direct Drive Coupling (Whirlpool / Kenmore / Roper / Estate)

The Direct Drive (motor) Coupling may be broken.
Many Whirlpool/Kenmore brands washing machines utilize a small, relatively inexpensive direct drive motor coupling. It's plastic and rubber and is mounted to the shaft of the motor on one side, and to the transmission on the other.

It can wear out over time or fail under overloading conditions. This protects your transmission from excessive loading.

All functions operate normally except the machine will not agitate.

Last the huming may be the motor is sized! Done, finished!

Hello,

Either of these three problems may be occurring.

Defective Lid Switch
Check lid switch for proper operation. Check the switch for continuity. If it is found to be open, replace the switch assembly.
