Motor Identification - How to determine Type and Part Number
Last Updated: 01/28/2019
Motor Identification:

WARNING ---
MANY Different MOTORS have LR14686 stamped on them.
And this number does NOT identify the GEAR used ( or RPM ).

If you have a FLECK valve ( 1/30 rpm motor ) it possibly would have a
part number on it,

120 volt would have B 13400 ( before year 2000 ) or 18743.

24 volt would have B 13494 ( before year 2000 ) or 19659.

And again -- the numbers 14686 are NOT your motors PART NUMBER.

**********
Example and more details about motor identification.


Left side top

120 v 60 HZ 3W = = common to many different motors... but you do need
to KNOW the Voltage and Hertz ( Hz ) of your motor.

E25571 = common to many many different motors... do NOT use to "ID" your motor.

Middle
DRV-2 RH = common to many many different motors... do NOT use to "ID"
your motor.

Right side
M2123 = common to many many different motors... do NOT use to "ID" your motor.

1/30 RPM

B13400 = old Part Number ( newer, since year 2000, should have 18743
for this replacement and voltage ).

170C96 = Date Code

Bottom right side.
LR14686 = common to many many different motors... do NOT use to "ID" your motor.



Numbers circled in BLUE are important, but just one is the Part Number
( although this is NOT always on the MOTOR.. many motors do NOT have a
cross referencing Part Number stamped on them ).
Numbers circled in RED are NOT useful to identify the motor.
They are common to many Different types of motors.

What is IMPORTANT is,
1 ) GEAR size - number of teeth - length
2 ) Voltage - 12 volt, 24 volt, 120 volt , 230 volt
3 ) Hz, which North American uses 60 Hz, and in Europe and many other
parts of the world, they use 50 Hz
4 ) Last but not least is the RPM ( some motors look the same but may
be a different RPM.. common are 1 RPM, 1/15 RPM, and 1/30 RPM )
5 ) Rotation - CW ( clock wise ) or CCW ( counter clock wise ) as
viewed when looking directly at the Gear side. Some motors are marked,
but many are not.

AS this SEARCH shows, there are many different timer motors, and most of similar "Pear" shape, but different GEARS / Voltage / RPM.

Another Question:
What is the average life of this timer motor?
My first one lasted over 10 years, but I've gone through 2 motors in less than 5 years, and I might need another one.
Why would that be, and is this "normal"?

Response:

Several things can cause the valve to "bind" or "get stuck" or wear out the motor ( since it's also the Drive Motor ).
see:
https://www.softenerparts.com/Fleck_5600_Rebuild_Stuck_Valve_s/51.htm

Missing PIN,
see:

and things you need to look DEEPER into, if not one of the more common reasons,
see:

** Summary:

The Timer Motor's "life" is effective by:

1 ) Stiff Pistons and Seals ( replacing them before motor is "damaged" )

2 ) Damaged Gears ( and Housing where Main Gear spins ). MORE INFO

3 ) Voltage surges ( we sell a lot of them here in Florida due to Lightning issues ).

4 ) Excessive heat ( if valve is installed outdoors ), effecting the plastic of the housing / gears.
