I can take a guess based on the "Eureka" typeface on the front and on the bag, which dates this to early/mid 1980's. It's the same time period in which the first Express and Mighty Mite canisters made their debuts with this new branding style. Earlier Eurekas had the classic "E" logo graphic you see in my avatar, and later ones italicized the new lettering so that it is slanted. Therefore, I'd say 1984 or 1985.
These 1400's were always great vacs: good carpet cleaners that were very lightweight and simple! I'm not much of an expert in motor rebuilds and repairs, though. :-) |

These vacs have rumbly motors. Post a video if you can. No blockages i guess... Probably just get a new motor if that is the problem. There is a newer style motor that probably will swap in, but hopefully someone who has done it will chime in. Sometimes Hepa bags can hinder air flow from what is nomally expected, especially if the bag is old or picked up damp or fine material. This post was last edited 01/05/2017 at 16:19 |

A sleeve bearing will probably not affect motor speed like that. The carbon brushes are far more likely the problem. I am not too familiar with this motor but given it's typical use in commercial vacuum's of the era i would imagine the brushes are an easy item to remove and replace because they wear out by design. This is why vacuum after-motor-filters soon darken with carbon. Unless it a brushless motor which are rare (new Rainbows are one) and your's isn't. Sleeve bearings rarely wear out and are easily rejuvintaed with a little sewing machine oil...not "3 in 1" oil! They are NOT interchangeable as 3 in 1 will evaporate...and btw never use wd-40 as a lubricant, it is a water displacer, i.e. "WD" formula #40. Sleeve bearings will absorb and hold the oil like a sponge. I suggest opening it up and check out those brushes (2), oil the bearing, then go from there.

My suggestion was to simply look at the brushes and lubricate the bearing. My recomendation is easy to do, cost free, and addresses the two obvious variables that have yet to be eliminated. But since you apparently have specific expertise Jae, what motors will this particular vacuum take without modification? If another type can be fitted, which is the better performer? Aaron, the red on this is nice, i hope you get it up to par or better without much trouble, whatever is ailing it. If you want the vac aspirated as originally built, 4 amps, tinker away. If bumping up the suction sounds appealing, i believe a higher power Eureka could be an option. Btw, what brush roll does it have? This post was last edited 01/07/2017 at 00:27 |

I had the same problem with my 1489. You can get a new complete motor for around $39.00. Mine was the top sleeve bearing as well. It's a shame I can't find the top housing only. CLICK HERE TO GO TO kloveland's LINK |
