Hey guys, I have an old Eureka upright model #1923 type A that works great but the plastic fan started to come apart. I looked on the Eureka parts list and it listed a part #12988-1 for the replacement. It seems there is a high profile and a low profile version on this same part number. My question is, how can I tell which one I have? The one I have is 5” diameter, 1/4” arbor, 7/8” high blade and a 1” over all height. I just want to make sure I get the correct one. Thanks, Jeff.

The lower profile fan was used on the Eureka 1400 series uprights, collectors call these blender motors. The motor is lower amp and sort of resembles a blender motor I guess.

The six amp and sometimes 5.5 amp motors (and above) use the higher profile fan and have the pancake motor.

The larger profile fan will not fit in the 1400 series uprights and due to the lower profile.

You probably need the higher profile fan if your machine is 6 amps or above and has the pancake motor.

Thanks for the info. I have a 5.5 amp motor. Sorry, I guess I should have included that in my post. I thought I might have the high profile one. Still wonder what the difference is in the dimensions, but I will make sure I get a high profile example. Thanks, Jeff.

The blades on the "tall" fan are close to an inch; the shorter are about 5/8" high.

My trick for knowing which to use is to check whether the motor's commutator and brushes are close to the bottom (necessitating a thicker lower plate which sticks into the main base leaving less room for the fan itself).

The "pancake" motor with brushes near the top, just under the cooling fan, gets the tall fan. The "blender" and "ESP" motors where the brushes are down low need a short fan.

Hope this helps.

Thanks! This helps. I definitely have a high profile fan. I have one on order and hope to have it soon. Thanks again, Jeff.

UPDATE:

Well I got my new high profile fan and the blades measure 15/16” high whereas my old fan blades measure 7/8” high. Everything else was the same. So I had to mill 1/16” off of each blade so it would fit the housing. I did this and my machine works like new again. My guess is that I have an old machine that was made during the changeover from the low profile fan to the newer high profile fan. My advice to anyone would be to carefully measure your old fan and make sure you get a replacement that is the same height. Thanks, Jeff.
